Hi there,
I've just realised that grep hasn't been highlighting results in
colour, and it occurred to me that I was sure it has supported this
facility for some time. Thus I discovered the --colour=always flag to
grep and trying to make this permanent I stumbled upon this site: http://www.ccs.neu.edu/home/katz/unix-colors.html
To find the part to which I refer you'll need to scroll down about
halfway through that page to "Colorize grep"; the author advises adding:
if echo hello|grep --color=auto l >/dev/null 2>&1; then
export GREP_OPTIONS='--color=auto' GREP_COLOR='1;32'
fi
to ~/.bashrc
Why does he echo hello, please? Is this to ensure that the file is
not sourced by a non-interactive shell, or by a script or something? I
understood that that was the difference between .bashrc
& .bash_profile, anyway - that "interactive commands" like colourising
stuff should go in .bashrc, to use /usr/local/mount instead of the
system on then one might alias that in .bash_profile.
It's early in the morning here, so obviously I'm not getting something.
Thanks in advance for any pointers,
Stroller.
