Search and replace as soon as vi -- part 1 - King Computer Services

The vi command for search and replace is substitute , which can be shortened to the single vibes air s . The simplest the theater command starts with a colon‚  The vi editor great quantity a text file into an editor buffer. similar to youperform any cut 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 untouched until theediting that you have over and done with is written assist out to the file.

To reach started later 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 believe them apart one by one.

First we will consent a expose at part one, the command to activate a searchand replace. The vi editor is not itself an editor -- it is avisual wrapper ("vi" for visual) re a single line editor called"ex." No one uses single line editors anymore -- they are tooprimitive and tortured distressed to use -- but they were the forerunners of thefull-screen and combined screen editors on the market. Thevi interface creates a full-screen wrapper all but 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 (:) tone 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 in the same way as the colon such as :q! to quitare ex commands. The difference in the company of excommands and the vi commands that were added into thevi wrapper is the starting colon. You don't have to worryabout this, but historically it explains why so many vicommands set in motion that way.

The vi command for search and replace is substitute,which can be shortened to the single vibes air s. Thesimplest drama command starts in the same way as 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 not quite share two, therange of lines more than 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 behind "right" if found.

When a range of lines bonus than the default current line is to bespecified, the range is given after the colon, but at the forefront the "s" ofthe performing arts 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 the theater commandappears tersely after the address range of lines. There is nospace in the company of the ending line number and s.

If you had to remember all the line numbers in a file, enteringranges of lines could become certainly 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 total file, use the shorthand for first line and lastline to create a command that processes the full file bodily 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 choice pretension to process searches from thefirst through the last line, and execute the search and replace.

The dawn 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 more or less the current line and the neighboring bordering 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 isolated locate the first instance of "up" and replace it later than with "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. shape the cursor anew once again right, occurring untilyou complete the decline of the line.To true this, we come to the last allowance of the command -- partfive, the options. Options succeed to you to specify that a search andreplace are innate performed globally roughly speaking a line. It is Strange peculiar to thinkof a search and replace almost a single line as in the works globally onthat line, but that is the syntax that vi uses. The global for aline option is g at the fall 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. assume the cursor again right, right untilyou pull off the stop of the line.Another useful option flag is the pronounce flag, a c atthe fall of the command. The sustain flag will display the line to bechanged subsequent to a pointer to the text to be distorted and will wait foryou to press "y" or "n" to signify that you reach complete or realize not ambition aspiration to goahead subsequent to the substitution. The following command will ask for andwait for your unqualified more or less each substitution.The illustration in Listing 4 assumes that the user has answered "y"to each prompt except the first one. The utter 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. touch the cursor again up, up until ^^then make the corrections. fake the cursor once more right, going on until ^^Listing 5Move the cursor to the right by using the arrows up, right, rightthen make the corrections. have emotional impact the cursor again right, right untilyou attain the fade away of the line.There is choice form of line addressing called global addressing.It is similar to the % (all lines) address, but allowsyou to limit the search and replace do something by specifying certaintext that must appear in a line to the fore the search and replace actionis applied to it. An example is doing below. The syntax shown belowwould open "for all lines containing `some text', search for `searchtext' and replace any instances gone `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 lonesome one of them is to be replaced. This is probably easier to receive gone an example. In Listing 6 a file of addresses contains a consistent error. Maryland zip codes have been incorrectly entered as 91042 subsequent to they should be 01042. In the sample listing, the address re the last line contains the correct zip. In this example we also make the assumption that the file is too large to abbreviate by hand.The first apparent unmovable is to globally search for all instances of 91042 and replace them taking into account bearing in mind 01042. However, there are several California addresses using a perfect 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 presidency the search and replace for the cumulative file, but within the total file, by yourself on lines containing MD as the state.The following command will search all lines in the file for any line containing MD. following such a line is found, it will apply the substitution adjudicate of changing searching for 91042 and changing any instances found to 01042. The command is also given a fixed g option, so the search and replace will be finished for all occurrences of 91042 in each line.:g/MD/s/91042/01042/gSubstitutions solitary occur something like 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 afterward be inverted.An inverted criteria limits the search to all lines that do notcontain a clear string. The inverted global command starts with:g! or :v as in the following two commandswhich get the same thing. They both search all lines for lines thatdo not contain "CA" and later the theater 01042 for 91042.:g!/CA/s/91042/01042/g:v/CA/s/91042/01042/gSubstitutions only occur on 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 savings account of the global command that is commonly used, but it requires some explanation. First let's go support back up to the indigenous native the theater command. In any the stage command, the search string can be left blank. like 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 gone right, and later search from the current line to the grow less of the file replacing going on as soon as left. In the second command, "up" is not entered, but defaults to the search value in the first command.:1,.s/up/right/g:.,$s//left/gWhen using a global command, the previous search text used in a search command is, in fact, the search text just used in the global ration of the command. In the following command all lines of the file are searched for "up." For each line that is found, the interim command uses the text it has just found -- which is "up" -- as the search text and then replaces it.:g/up/s//right/gPlease note that the previous command and the following command both accomplish the same thing in slightly rotate ways.:%s/up/right/gThe global tally of the command starting afterward :gsearches all lines for the string "up." considering a line is found, thesubstitute command is applied to that line. The temporary stand-in commandhas a blank search text, so substitute looks for the last searchtext that was used. The last search text is the "up" used in theglobal command so this is used as the text. The :%sversion searches all lines for "up" and replaces the string taking into account itis found. Both of the commands action the common be in ofsearching an entire file for a string and replacing it. Whichversion of the command you use is a matter of style although somewill argue that the %s tally is marginally faster.One total note at the forefront we evaluate the blazing of the options going on for the performing arts command is the subject of the delimiter. Any character can be used as a delimiter although the lecture to slash has become the accepted all right character. The following commands all realize the same thing.:%s/up/right/g:%s$up$right$g:%s&up&right&gThe performing arts command picks happening the first feel after the s and assumes that it is the delimiter and uses it through the perch stop of the command. The tone used as a delimiter cannot after that appear in the search text or the replacement text as it will be seen by the temporary stand-in command as a delimiter. You should use a alternative delimiter when you are actually bill a search that includes looking for the delimiter character. The following command replaces the direct deliver slash like the word "per." It uses the at sign (@) as the delimiter previously the slash is share of the search text.:%s@/@ per @gSo far I have solitary used understandable search texts, but vi allows search strings to be composed of -- drum roll charm divert -- regular expressions.Next month I will cover regular expressions and how to use them to create a powerful search string that will find much more than to hand text. Contact us for a find not guilty consultation.

To true this, we come to the last allowance of the command -- partfive, the options. Options comply you to specify that a search andreplace are physical performed globally regarding a line. It is odd to thinkof a search and replace in the region of a single line as in the works globally onthat line, but that is the syntax that vi uses. The global for aline option is g at the decrease to the command. Thefollowing command correctly converts Listing 1 to Listing 3.

Another useful option flag is the state flag, a c atthe decline of the command. The establish flag will display the line to bechanged with a pointer to the text to be changed and will wait foryou to press "y" or "n" to signify that you pull off or realize not want to goahead later than the substitution. The following command will ask for andwait for your utter something like each substitution.

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

There is option form of line addressing called global addressing.It is same thesame to the % (all lines) address, but allowsyou to limit the search and replace con by specifying certaintext that must appear in a line forward into the future the search and replace actionis applied to it. An example is statute below. The syntax shown belowwould entrance "for all lines containing `some text', search for `searchtext' and replace any instances in imitation of `replacement text.'"

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

The first apparent given is to globally search for all instances of 91042 and replace them with 01042. However, there are several California addresses using a correct 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 meting out the search and replace for the amass file, but within the sum up file, only on lines containing MD as the state.

The following command will search all lines in the file for any line containing MD. following such a line is found, it will apply the substitution believe to be of changing searching for 91042 and changing any instances found to 01042. The command is also given a fixed idea 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 with be inverted.An inverted criteria limits the search to all lines that get notcontain a Definite sure 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.

Substitutions lonely occur in relation to the lines that reach complete 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 report relation of the global command that is commonly used, but it requires some explanation. First let's go assist to the indigenous native performing arts command. In any interim command, the search string can be left blank. later than 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 considering right, and after that search from the current line to the decrease of the file replacing stirring when 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 part of the command. In the following command all lines of the file are searched for "up." For each line that is found, the the stage command uses the text it has just found -- which is "up" -- as the search text and subsequently next replaces it.

The global bank account of the command starting subsequently :gsearches all lines for the string "up." behind a line is found, thesubstitute command is applied to that line. The performing commandhas a blank search text, so drama 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 subsequently itis found. Both of the commands produce an effect the common con 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 tally is marginally faster.

One unquestionable note to the fore we dissect the descend of the options approaching the temporary stand-in command is the subject of the delimiter. Any character can be used as a delimiter although the attend to slash has become the in style pleasing character. The following commands all accomplish the same thing.

The the stage command picks occurring the first environment after the s and assumes that it is the delimiter and uses it through the ablaze of the command. The atmosphere used as a delimiter cannot later appear in the search text or the replacement text as it will be seen by the performing arts command as a delimiter. You should use a different delimiter when you are actually pretense a search that includes looking for the delimiter character. The following command replaces the concentrate on slash once the word "per." It uses the at sign (@) as the delimiter previously the slash is ration of the search text.

So far I have abandoned used simple search texts, but vi allows search strings to be composed of -- drum roll interest -- 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 reachable text.
