Here are some other commands that find matches for a regular
expression. They all ignore case in matching, if the pattern contains
no upper-case letters and
case-fold-search is non-
occur and its variants, all operate on the text from
point to the end of the buffer, or on the region if it is active.
Prompt for one or more buffer names, ending with RET; then, begin a multi-buffer incremental search in those buffers. (If the search fails in one buffer, the next C-s tries searching the next specified buffer, and so forth.) With a prefix argument, prompt for a regexp and begin a multi-buffer incremental search in buffers matching that regexp.
This command is just like
multi-isearch-buffers, except it
performs an incremental regexp search.
Prompt for a regexp, and display a list showing each line in the buffer that contains a match for it. To limit the search to part of the buffer, narrow to that part (see Narrowing). A numeric argument n specifies that n lines of context are to be displayed before and after each matching line.
In the *Occur* buffer, you can click on each entry, or move
point there and type RET, to visit the corresponding position in
the buffer that was searched. o and C-o display the match
in another window; C-o does not select it. Alternatively, you
can use the C-x ` (
next-error) command to visit the
occurrences one by one (see Compilation Mode).
Typing e in the *Occur* buffer switches to Occur Edit mode, in which edits made to the entries are also applied to the text in the originating buffer. Type C-c C-c to return to Occur mode.
The command M-x list-matching-lines is a synonym for M-x occur.
occur using the search string of the last incremental
string search. You can also run M-s o when an incremental
search is active; this uses the current search string.
This command is just like
occur, except it is able to search
through multiple buffers. It asks you to specify the buffer names one
This command is similar to
multi-occur, except the buffers to
search are specified by a regular expression that matches visited file
names. With a prefix argument, it uses the regular expression to
match buffer names instead.
Prompt for a regexp, and print the number of matches for it in the buffer after point. If the region is active, this operates on the region instead.
Prompt for a regexp, and delete each line that contains a match for it, operating on the text after point. This command deletes the current line if it contains a match starting after point. If the region is active, it operates on the region instead; if a line partially contained in the region contains a match entirely contained in the region, it is deleted.
If a match is split across lines,
flush-lines deletes all those
lines. It deletes the lines before starting to look for the next
match; hence, it ignores a match starting on the same line at which
another match ended.
Prompt for a regexp, and delete each line that does not contain a match for it, operating on the text after point. If point is not at the beginning of a line, this command always keeps the current line. If the region is active, the command operates on the region instead; it never deletes lines that are only partially contained in the region (a newline that ends a line counts as part of that line).
If a match is split across lines, this command keeps all those lines.
