Replace Replace Regexp Replace
Replace every occurrence of string with newstring.
||Replace every match for regexp with newstring.|
To replace every instance of `
foo' after point with `
use the command M-x replace-string with the two arguments
foo' and `
bar'. Replacement happens only in the text after
point, so if you want to cover the whole buffer you must go to the
beginning first. All occurrences up to the end of the buffer are
replaced; to limit replacement to part of the buffer, narrow to that
part of the buffer before doing the replacement (see Narrowing).
In Transient Mark mode, when the region is active, replacement is
limited to the region (see Transient Mark).
replace-string exits, it leaves point at the last
occurrence replaced. It sets the mark to the prior position of point
replace-string command was issued); use C-u C-
SPC to move back there.
A numeric argument restricts replacement to matches that are surrounded by word boundaries. The argument's value doesn't matter.Replace Replace Regexp Replace
