15.10.1 Unconditional Replacement
- M-x replace-string RET
stringRETnewstringRET - Replace every occurrence of
stringwithnewstring.
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, activate the
region around that part. When the region is active, replacement is
limited to the region (see Mark).
When replace-string exits, it leaves point at the last
occurrence replaced. It adds the prior position of point (where the
replace-string command was issued) to the mark ring, without
activating the mark; use C-u C-SPC to move back there.
See Mark Ring.
A prefix argument restricts replacement to matches that are surrounded by word boundaries.
See Replacement and Lax Matches, for details about case-sensitivity and character folding in replace commands.
