ag

The Silver Searcher. Like ack, but faster.

• Find files containing "foo", and print the line matches in context:

ag foo

• Find files containing "foo", but only list the filenames:

ag -l foo

• Find files containing "FOO" case-insensitively, and print only the match, rather than the whole line:

ag -i -o FOO

• Find "foo" in files with a name matching "bar":

ag foo -G bar

• Find files whose contents match a regular expression:

ag '^ba(r|z)$'

• Find files with a name matching "foo":

ag -g foo
