multi-occur

multi-occur is an interactive compiled Lisp function in `replace.el'.


(multi-occur BUFS REGEXP &optional NLINES)

Show all lines in buffers BUFS containing a match for REGEXP.
This function acts on multiple buffers; otherwise, it is exactly like
`occur'. When you invoke this command interactively, you must specify
the buffer names that you want, one by one.
