With --heading, the filename is printed once before matches from that file instead of at the start of each line, giving more screen space to the actual search results. This option is taken from ack (http://betterthangrep.com/). And now git grep can dress up like it: $ git config alias.ack "grep --break --heading --line-number" $ git ack -e --heading Documentation/git-grep.txt 154:--heading:: t/t7810-grep.sh 785:test_expect_success 'grep --heading' ' 786: git grep --heading -e char -e lo_w hello.c hello_world >actual && 808: git grep --break --heading -n --color \ Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
