Hi,

If you work on the command line, here is a handy grep trick.

In your .bashrc put:

export GREP_COLOR=33
alias grep='grep --colour=always'

You can always try different values of GREP_COLOR.
Although I can't seem to get yellow.

Remember to:

source .bashrc

before trying it.

This will break any scripts which assume that the output
of grep has not been annotated with color escape sequences.

Very cool tip!! In my case, however, my .cshrc file might be a better
choice since I don't use bash, and of course the syntax is different. As
someone else pointed out the above will break scripts that use grep. A
moment or two of Googling turned up another option. If one uses
--color=auto, it will colorize output going to a terminal but won't if the
output is piped to another command or redirected to a file. The downside
is that with --color=auto output piped to less -r doesn't get colorized.
I'm sure there's a creative way to keep from breaking existing scripts and
still be able to view colorized output via less.

After another moment of Googling, for yellow, use:

setenv GREP_COLOR '1;33'

or your shell's equivalent.

The GREP_OPTIONS and GREP_COLOR environment variables created some problems
for me a while ago (See
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=411931 )

So instead of aliasing grep with color related options, I am currently using

if [ ! -z "$PS1" ]; then
function colgrep(){ command grep --color=always "$@"; }
fi

Thanks, even works in bash, but
yeah, I found that through dircolors -p, didn't even need to go online.
>From the manpage it wasn't clear what arguments GREP_COLOR took. I
started with GREP_COLOR=brown :-) which didn't work. Then started trying
different numbers, which seemed to miss out on a few colours, so
as a thought I tried "man -k colour" ... nothing ... ...
Arrrgh, of course, "man -k color" ... yes! dircolors. But, for some reason
because "ls" didn't show any yellow I didn't click about the "1;" :-(,
also the semi colon put me off, I mean a '1;' in a script could be
problematic?

Which ones? e.g ... as me:

echo $GREP_COLOR
33

less gtt
#!/bin/bash

echo $GREP_COLOR

./gtt
33

So any scripts run *as* me get it too.

More precicely, any scripts you run from interactive sessions (terminal etc).
Scripts started under your UID from cron, at, etc, will not get the
GREP_COLOR var.

At least in unstable:

"grep --color=auto" works nicely. So I think we can alias or use
GREP_OPTIONS='--color=auto'; export GREP_OPTIONS

Also, "GREP_COLORS" should be used instead of "GREP_COLOR".

Anyway, it was interesting.
