Text substitution in vim: 1. Replace the contents of the current line: :s/from/to/ (S is substitude) :s/from/to/ : replaces the first from in the current line with a to. If the current row contains more than one from, only the first one is replaced. :s/from/to/g : Replaces all the from in the current row with to.         :S/FROM/TO/GC : Replaces all the from in the current row with to, but each time the substitution is will ask the user to confirm this action. Note: Both from and to can be any string, where the from can also be a regular expression. 2. Replace the contents of a line: : 33s/from/to/g :.s/from/to/g : Replace operation on current line. :33s/from/to/g  : On line 33rd for the replacement operation.        &NBSP: $s/from/to/g : Replace on the last line. 3. Replace the contents of some lines: :10,20s/from/to/g : 10,20s/from/to/g : Replaces the contents of lines 10th through 20th. :1, $s/from/to/g : Replaces the contents of the first row to the last row (that is, the entire text). :1,.s/from/to/g : Replaces the contents of the first line to the current line. :., $s/from/to/g : Replaces the contents of the current row to the last row. : ' A, ' bs/from/to/g : replaces the line between A and B, with the row where A and B are located. where A and B are tokens that were previously made with the M command. 4. Replace the contents of all lines: :%s/from/to/g :%s/ From/to/g : Replaces the contents of all rows. 5. Replacement command in full form: :[range]s/from/to/[flags] 5.1 s/from/to/ replaces the string specified by the from with the string specified by to. The from can be a regular expression. 5.2 [range] has some of the following presentation methods: Do not write range : defaults to the line where the cursor is located. . : CursorsThe line where you are located. 1 : first line. $ : last line. 33 : line 33rd. ' a   &NBSP: marks a row (previously marked with MA). .+1   &NBSP: The line below which the current cursor is located. $-1   &NBSP: Countdown second line. (This shows that we can add a value to a line to obtain a relative line). 22,33 : Line 22nd to 33rd. 1,$   &NBSP: 1th line to the last row. 1,.        &NBSP: 1th line to the current line. .,$   &NBSP: Current row to the last row. ' A, ' B &NBSP: marks a row to the row where Mark B is located. % : All rows (equivalent to 1,$). &nbSp; ?chapter? : Search up from the current position, and the row where the first chapter is located. ( where chapter can be any string or regular expression. /chapter/ : Search down from the current position, The row where the first chapter was found. ( where chapter can be any string or regular expression. Note that all of the above representations for range can be done by +,- Action to set the relative offset shift amount. 5.3 [flags] The flags available here are: & nbsp; no : Replaces only the first occurrence within a specified range. g : Replaces all occurrences within the specified range. c : Ask the user for confirmation before replacing. e : ignores errors in the execution process. NOTE: All flags above can be used together, such as GC Represents a replacement for all occurrences of in a specified range, and the user is asked to confirm before each substitution.
