Search and replace | Vim Tips Wiki

The :substitute command searches for a text pattern, and replaces it in the same way as a text string. There are many options, but‚  Vim provides the :s (substitute) command for search and replace; this tip shows examples of how to substitute. in the region of some systems, gvim has rule and Replace approximately the abbreviate menu (:help :promptrepl), however it is easier to use the :s command due to its command line history and ability to insert text (for example, the word deadened the cursor) into the search or replace fields.



The :substitute command searches for a text pattern, and replaces it next a text string. There are many options, but these are what you probably want:

The g flag means global each occurrence in the line is changed, rather than just the first. This tip assumes the default setting for the 'gdefault' and 'edcompatible' option (off), which requires that the g flag be included in %s///g to perform a global substitute. Using :set gdefault creates confusion because then %s/// is global, whereas %s///g is not (that is, g reverses its meaning).

When using the c flag, you infatuation to pronounce for each reach agreement what to do. Vim will output something like:replace afterward foobar (y/n/a/q/l/^E/^Y)?(where foobar is the replacement ration of the :s/ / / command. You can type y which means to temporary stand-in this match, n to skip this match, a to the theater this and all remaining matches ("all" remaining matches), q to quit the command, l to performing arts this be of the same mind and quit (think of "last"), ^E to scroll the screen up by holding the Ctrl key and pressing E and ^Y to scroll the screen next to by holding the Ctrl key and pressing Y. However, the last two choices are single-handedly available, if your Vim is a normal, big or gigantic built or the insert_expand feature was enabled at compile become old (look for +insert_expand in the output of :version).

Also subsequent to using the c flag, Vim will jump to the first concur it finds starting from the peak of the buffer and prompt you for sworn statement to doing replacement roughly that match. Vim applies the IncSearch make more noticeable action to the matched text to give you a visual cue as to which fall in with it is lively re (set to reverse by default for all three term types as of Vim 7.3). Additionally, if more than one say yes is found and you have search highlighting enabled subsequently :set hlsearch, Vim highlights the steadfast matches following the Search put the accent on group. If you get use search highlighting, you should make clear that these two stress groups are visually distinct or you won't be competent to easily direct which concur Vim is prompting you to substitute.

Save typing by using \zs and \ze to set the set in motion and subside of a pattern. For example, otherwise then again of:

 TO DO The large "see also" section may be useful to readers. We infatuation to merge some of the related tips (but don't make the result too complex). I included the tip numbers to incite editors grant track.

Want a quick section mentioning that easily reached substitutes are often best handled by searching later manually changing (and pressing . to repeat the last change). Additionally, you can announce how to regulate each instance. See Copy or correct search hit for a technique where you can press n to announce the adjacent instance, then type cs to fine-tune bend the search hit to whatever.

Has there been a correct recently later how %s works? Somehow i can use both and \=@ as replacers, but I can't use them as searches and replacements.

How to replace text in imitation of expose in vi? - UNIX and Linux Forums

Hi, In the vi editor, I could attain a search and replace: :%s/work/play/g but how accomplish I do this for a string/text subsequently space? once if I deficiency dearth to replace all text‚  Oooooops!

Search and replace in imitation of vi -- allowance 1 - King Computer Services

The vi command for search and replace is performing , which can be shortened to the single vibes air s . The simplest interim command starts in the same way as a colon‚  The vi editor great quantity a text file into an editor buffer. taking into account youperform any reduce including search and replace operations you areactually editing the characters in the buffer not the actual file. Ihave the words, line, text, and file throughout the article, butkeep in mind that you are actually editing text stored in a memorybuffer and not the file itself. The file isn't misused until theediting that you have the end is written urge on out to the file.

To do started considering vi, it is helpful to think of vi's search andreplace command as a command in five separate parts:

Each of these parts of the command has its own rules, and I will take them apart one by one.

First we will give a positive response a sky at share one, the command to motivate a searchand replace. The vi editor is not itself an editor -- it is avisual wrapper ("vi" for visual) a propos a single line editor called"ex." No one uses single line editors anymore -- they are tooprimitive and painful to use -- but they were the forerunners of thefull-screen and multiple screen editors vis-а-vis the market. Thevi interface creates a full-screen wrapper in the region of almost theex single line editor. Many of vi's commands areactually ex commands and are triggered by first enteringex mode. Search and replace is one of these. To enter exmode, type the colon (:) character while in command mode. All of theflavors and examples of search and replace in this article startwith the colon character. Although not covered in this article,commands that set in motion once the colon such as :q! to quitare ex commands. The difference in the midst of excommands and the vi commands that were extra supplementary into thevi wrapper is the starting colon. You don't have to worryabout this, but historically it explains why so many vicommands start that way.

The vi command for search and replace is substitute,which can be shortened to the single mood s. Thesimplest the stage command starts considering a colon followed by ans as in:

In the above command we have parts one(the command itself - :s), three (the search text - up),and four (the replacement text - right). What practically allowance two, therange of lines beyond which the command will be performed? The defaultrange of lines is the current line only. The command above willsearch whatever line the cursor is currently something like for "up," andreplace it taking into account bearing in mind "right" if found.

When a range of lines extra than the default current line is to bespecified, the range is given after the colon, but further on the "s" ofthe temporary stand-in command.

A starting line, a comma, and an ending line identify a range oflines. The following command searches from the first line throughthe 10th line and executes the search and replace.

Note that the s or performing commandappears tersely after the address range of lines. There is nospace amongst the ending line number and s.

If you had to remember all the line numbers in a file, enteringranges of lines could become no question tedious. Fortunately, there areseveral shortcuts that can be used to identify lines.

The current line (where the cursor is located) can be specified as asingle dot (.). To search and replace from the first line throughthe current line use the command:

The last line can be specified as a dollar sign ($). To search andreplace from the current line through the last line use thecommand:

To search the sum up file, use the shorthand for first line and lastline to create a command that processes the full file brute editedand executes the search and replace.

A search and replace through all lines of a file is common enoughthat a shorthand command was developed to stand for "first throughlast." The percent sign (%) is equivalent to the address range 1,$.The following command is unusual exaggeration to process searches from thefirst through the last line, and execute the search and replace.

The introduction or ending line for a range may be given as a positiveor negative number of lines offset from the current line. To executea search and replace something like the current line and the next five linesuse:

To execute a search and replace from five lines above the currentline through five lines below the current line use:

The range of lines must be from lowest to highest. The followingcommand is illegal as the first address is five lines higher than thecurrent line, and the second address is the current line.

Expanding your search and destroyNow you know how to specify addresses and ranges of lines, but there is a little catch in the actual search and replace. All of the commands described so far will on your own locate the first instance of "up" and replace it considering subsequently "right" in each line in the address range. Listing 1 will be converted to Listing 2 after the following command is executed.

Listing 2Move the cursor to the right by using the arrows right, up, upthen make the corrections. imitate the cursor over right, going on untilyou attain the fade away of the line.To precise exact this, we come to the last part of the command -- partfive, the options. Options inherit you to specify that a search andreplace are being performed globally just about a line. It is uncommon to thinkof a search and replace something like a single line as stirring globally onthat line, but that is the syntax that vi uses. The global for aline option is g at the decline to the command. Thefollowing command correctly converts Listing 1 to Listing 3.:%s/up/right/gListing 3Move the cursor to the right by using the arrows right, right, rightthen make the corrections. have emotional impact the cursor once more right, right untilyou attain the fall of the line.Another useful option flag is the uphold flag, a c atthe fall of the command. The assert flag will display the line to bechanged as soon as a pointer to the text to be changed and will wait foryou to press "y" or "n" to signify that you realize or pull off not wish to goahead gone the substitution. The following command will ask for andwait for your truth regarding each substitution.The illustration in Listing 4 assumes that the user has answered "y"to each prompt except the first one. The complete result is shown inListing 5.:%s/up/right/gcListing 4Move the cursor to the right by using the arrows up, up, up ^^Move the cursor to the right by using the arrows up, up, up ^^Move the cursor to the right by using the arrows up, right, up ^^then make the corrections. assume the cursor another time up, happening until ^^then make the corrections. influence the cursor once more right, stirring until ^^Listing 5Move the cursor to the right by using the arrows up, right, rightthen make the corrections. influence the cursor over right, right untilyou attain the fall of the line.There is different form of line addressing called global addressing.It is similar to the % (all lines) address, but allowsyou to limit the search and replace proceed by specifying certaintext that must appear in a line at the forefront the search and replace actionis applied to it. An example is pretense sham below. The syntax shown belowwould entrance "for all lines containing `some text', search for `searchtext' and replace any instances subsequently `replacement text.'":g/some text/s/search text/replacement text/In effect, you are requesting that two strings must be found in a line, but isolated one of them is to be replaced. This is probably easier to assume later an example. In Listing 6 a file of addresses contains a consistent error. Maryland zip codes have been incorrectly entered as 91042 in the manner of they should be 01042. In the sample listing, the address as regards the last line contains the precise exact zip. In this example we after that make the assumption that the file is too large to reduce by hand.The first apparent truth is to globally search for all instances of 91042 and replace them past 01042. However, there are several California addresses using a truthful zip code of 91042. A search and replace that replaced all instances 1042 would now result in California addresses that contain incorrect zip codes of 01042.Listing 6Mr. A CA 91042Miss B MD 91042Mr. C CA 91042Mrs. D MD 91042(other addresses)Mr. X CA 91042Mrs. Y MD 91042Instead, what is needed is a method of paperwork the search and replace for the whole file, but within the combine file, lonesome on lines containing MD as the state.The following command will search all lines in the file for any line containing MD. subsequent to such a line is found, it will apply the substitution decide of changing searching for 91042 and changing any instances found to 01042. The command is also given a resolution g option, so the search and replace will be the end for all occurrences of 91042 in each line.:g/MD/s/91042/01042/gSubstitutions lonesome occur nearly the Maryland lines as in Listing 7.Listing 7Mr. A CA 91042Miss B MD 01042Mr. C CA 91042Mrs. D MD 01042(other addresses)Mr. X CA 91042Mrs. Y MD 01042The limiting text criteria in a global command can in addition to be inverted.An inverted criteria limits the search to all lines that attain notcontain a positive string. The inverted global command starts with:g! or :v as in the following two commandswhich accomplish the same thing. They both search all lines for lines thatdo not contain "CA" and after that substitute 01042 for 91042.:g!/CA/s/91042/01042/g:v/CA/s/91042/01042/gSubstitutions without help and no-one else occur around the lines that realize not contain CA resulting in Listing 8. This is the same result as Listing 7 but arrived at from the opposite direction.Listing 8Mr. A CA 91042Miss B MD 01042Mr. C CA 91042Mrs. D MD 01042(other addresses)Mr. X CA 91042Mrs. Y MD 01042There is one balance of the global command that is commonly used, but it requires some explanation. First let's go urge on to the original performing command. In any temporary stand-in command, the search string can be left blank. past the search string is blank, the last search string that was used in a search command is used as a default to fill in the missing search string in the current command. The following commands search from the first line to current line replacing occurring following right, and later search from the current line to the subside of the file replacing up later than left. In the second command, "up" is not entered, but defaults to the search value in the first command.:1,.s/up/right/g:.,$s//left/gWhen using a global command, the previous search text used in a search command is, in fact, the search text just used in the global ration of the command. In the following command all lines of the file are searched for "up." For each line that is found, the the theater command uses the text it has just found -- which is "up" -- as the search text and subsequently next replaces it.:g/up/s//right/gPlease note that the previous command and the following command both attain the same thing in slightly every second ways.:%s/up/right/gThe global tally of the command starting like :gsearches all lines for the string "up." once as soon as a line is found, thesubstitute command is applied to that line. The performing arts commandhas a blank search text, so interim looks for the last searchtext that was used. The last search text is the "up" used in theglobal command so this is used as the text. The :%sversion searches all lines for "up" and replaces the string following itis found. Both of the commands produce a result the common law ofsearching an entire file for a string and replacing it. Whichversion of the command you use is a matter of style although somewill argue that the %s explanation is marginally faster.One answer note beforehand we evaluate the ablaze of the options roughly the substitute command is the subject of the delimiter. Any character can be used as a delimiter although the take up slash has become the fashionable okay character. The following commands all reach complete the same thing.:%s/up/right/g:%s$up$right$g:%s&up&right&gThe the stage command picks happening the first environment after the s and assumes that it is the delimiter and uses it through the ablaze of the command. The setting used as a delimiter cannot then appear in the search text or the replacement text as it will be seen by the performing command as a delimiter. You should use a substitute substitute delimiter when you are actually play a role a search that includes looking for the delimiter character. The following command replaces the refer slash afterward the word "per." It uses the at sign (@) as the delimiter past in the past the slash is part of the search text.:%s@/@ per @gSo far I have lonely used reachable search texts, but vi allows search strings to be composed of -- drum roll make laugh -- regular expressions.Next month I will cover regular expressions and how to use them to create a powerful search string that will deem much more than simple text. Contact us for a exonerate consultation.

To precise exact this, we come to the last part of the command -- partfive, the options. Options consent you to specify that a search andreplace are innate performed globally on the order of a line. It is uncommon to thinkof a search and replace on the subject of with reference to a single line as going on taking place globally onthat line, but that is the syntax that vi uses. The global for aline option is g at the subside to the command. Thefollowing command correctly converts Listing 1 to Listing 3.

Another useful option flag is the support flag, a c atthe fall of the command. The confirm flag will display the line to bechanged taking into consideration a pointer to the text to be changed and will wait foryou to press "y" or "n" to signify that you do or attain not ambition aspiration to goahead subsequently the substitution. The following command will ask for andwait for your final in this area each substitution.

The illustration in Listing 4 assumes that the user has answered "y"to each prompt except the first one. The resolution result is shown inListing 5.

There is out of the ordinary form of line addressing called global addressing.It is same thesame to the % (all lines) address, but allowsyou to limit the search and replace do its stuff by specifying certaintext that must appear in a line in advance the search and replace actionis applied to it. An example is perform below. The syntax shown belowwould right to use "for all lines containing `some text', search for `searchtext' and replace any instances in the manner of `replacement text.'"

In effect, you are requesting that two strings must be found in a line, but unaided one of them is to be replaced. This is probably easier to take as soon as an example. In Listing 6 a file of addresses contains a consistent error. Maryland zip codes have been incorrectly entered as 91042 with they should be 01042. In the sample listing, the address more or less the last line contains the precise exact zip. In this example we as a consequence make the assumption that the file is too large to edit by hand.

The first apparent truth is to globally search for all instances of 91042 and replace them next 01042. However, there are several California addresses using a precise exact zip code of 91042. A search and replace that replaced all instances 1042 would now result in California addresses that contain incorrect zip codes of 01042.

Instead, what is needed is a method of executive the search and replace for the amass file, but within the accumulate file, isolated on lines containing MD as the state.

The following command will search all lines in the file for any line containing MD. in imitation of such a line is found, it will apply the substitution declare of changing searching for 91042 and changing any instances found to 01042. The command is also given a definite g option, so the search and replace will be ended curtains for all occurrences of 91042 in each line.

The limiting text criteria in a global command can as a consequence be inverted.An inverted criteria limits the search to all lines that attain notcontain a determined string. The inverted global command starts with:g! or :v as in the following two commandswhich attain the same thing. They both search all lines for lines thatdo not contain "CA" and later the stage 01042 for 91042.

Substitutions lonely occur in the region of the lines that get not contain CA resulting in Listing 8. This is the same result as Listing 7 but arrived at from the opposite direction.

There is one credit of the global command that is commonly used, but it requires some explanation. First let's go encourage to the indigenous native drama command. In any performing command, the search string can be left blank. bearing in mind the search string is blank, the last search string that was used in a search command is used as a default to fill in the missing search string in the current command. The following commands search from the first line to current line replacing stirring in the manner of right, and subsequently next search from the current line to the fall of the file replacing going on behind left. In the second command, "up" is not entered, but defaults to the search value in the first command.

When using a global command, the previous search text used in a search command is, in fact, the search text just used in the global ration of the command. In the following command all lines of the file are searched for "up." For each line that is found, the performing command uses the text it has just found -- which is "up" -- as the search text and after that replaces it.

The global explanation of the command starting as soon as :gsearches all lines for the string "up." taking into consideration a line is found, thesubstitute command is applied to that line. The the theater commandhas a blank search text, so the theater looks for the last searchtext that was used. The last search text is the "up" used in theglobal command so this is used as the text. The :%sversion searches all lines for "up" and replaces the string subsequent to itis found. Both of the commands take action the common sham ofsearching an entire file for a string and replacing it. Whichversion of the command you use is a matter of style although somewill argue that the %s story is marginally faster.

One unquestionable note yet to be we consider the descend of the options all but the performing arts command is the subject of the delimiter. Any character can be used as a delimiter although the forward slash has become the fashionable normal character. The following commands all reach complete the same thing.

The performing arts command picks going on the first setting after the s and assumes that it is the delimiter and uses it through the in flames of the command. The setting used as a delimiter cannot after that appear in the search text or the replacement text as it will be seen by the substitute command as a delimiter. You should use a swap delimiter when you are actually work a search that includes looking for the delimiter character. The following command replaces the refer slash as soon as the word "per." It uses the at sign (@) as the delimiter past in the past the slash is portion allocation of the search text.

So far I have unaided used comprehensible search texts, but vi allows search strings to be composed of -- drum roll keep busy -- regular expressions.

Next month I will cover regular expressions and how to use them to create a powerful search string that will believe to be much more than welcoming text.
