a601d313 | 71 | "Use special markers to highlight grep matches. |
277df088 JL |
72 | |
73 | Some grep programs are able to surround matches with special | |
74 | markers in grep output. Such markers can be used to highlight | |
a915d7a1 GM |
75 | matches in grep mode. This requires `font-lock-mode' to be active |
76 | in grep buffers, so if you have globally disabled font-lock-mode, | |
77 | you will not get highlighting. | |
277df088 | 78 | |
a601d313 | 79 | This option sets the environment variable GREP_COLORS to specify |
277df088 JL |
80 | markers for highlighting and GREP_OPTIONS to add the --color |
81 | option in front of any explicit grep options before starting | |
a58c94a2 JL |
82 | the grep. |
83 | ||
a601d313 JL |
84 | When this option is `auto', grep uses `--color=auto' to highlight |
85 | matches only when it outputs to a terminal (when `grep' is the last | |
86 | command in the pipe), thus avoiding the use of any potentially-harmful | |
87 | escape sequences when standard output goes to a file or pipe. | |
88 | ||
89 | To make grep highlight matches even into a pipe, you need the option | |
90 | `always' that forces grep to use `--color=always' to unconditionally | |
91 | output escape sequences. | |
