K.7.1 Unconditional Replacement

M-x replace-string RET string RET newstring RET
Replace every occurrence of string with newstring.
M-x replace-regexp RET regexp RET newstring RET
Replace every match for regexp with newstring.

To replace every instance of `foo' after point with `bar', 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 section AC.22 Narrowing). In Transient Mark mode, when the region is active, replacement is limited to the region (see section H.2 Transient Mark Mode).

When replace-string exits, it leaves point at the last occurrence replaced. It sets the mark to the prior position of point (where the 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.
