# ag > The Silver Searcher. Like `ack`, but aims to be faster. > More information: . - Find files containing "foo", and print the line matches in context: `ag {{foo}}` - Find files containing "foo" in a specific directory: `ag {{foo}} {{path/to/directory}}` - Find files containing "foo", but only [l]ist the filenames: `ag -l {{foo}}` - Find files containing "FOO" case-[i]nsensitively, and print [o]nly 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}}`
