In Emacs, how can I search for and replace text?
Emacs has two types of search and replace functions: unconditional and queried.
Note: If you aren't sure how to enter the following commands in Emacs, see In Emacs, how are keystrokes denoted?
Unconditional search and replace
To perform an unconditional search and replace, press
M-x. Then enter:
replace-string RET your_search_string RET your_replace_string
your_search_string with the existing text
string you want to find and remove, and replace
your_replace_string with the new text you want to add
in its place.
Queried search and replace
To do a queried search and replace (with a prompt for replacing each
occurrence of a text string), press
M-%. You will then
be prompted for your search and replace strings. Emacs will find
and display each occurrence of the search string and ask you for
further instructions. You can respond with any of the following
Replace text and find the next occurrence
Leave text as is and find the next occurrence
Replace text, then stop looking for occurrences
Replace all occurrences without asking
Return the cursor to previously replaced text
If you type any other character, Emacs will stop looking for occurrences and execute the character as a command. To restart the queried search and replace, type:
C-x M- M-RET
