lgrep
lgrep is an interactive autoloaded compiled Lisp function in `grep.el
'.
(lgrep REGEXP &optional FILES DIR CONFIRM)
Run grep, searching for REGEXP in FILES in directory DIR.
The search is limited to file names matching shell pattern FILES.
FILES may use abbreviations defined in `grep-files-aliases', e.g.
entering `ch' is equivalent to `*.[ch]'.
With C-u prefix, you can edit the constructed shell command line
before it is executed.
With two C-u prefixes, directly edit and run `grep-command'.
Collect output in a buffer. While grep runs asynchronously, you
can use C-x ` (M-x next-error), or RET in the grep output buffer,
to go to the lines where grep found matches.
This command shares argument histories with M-x rgrep and M-x grep.
