Package: a lot of them
I've recently set GREP_OPTIONS='--color=always' in my bashrc. I do this
mainly so that I can see grep's highlighted findings even when viewing
through a pipeline, such as with less. '--color=auto' won't work
because it will turn off the color escapes if it's going down the
pipeline, which is not what I want when I use less.
This poses a problem for a lot of scripts, which assume that text coming
from their stdin is free from (color) escapes. For instance, I recently
went to install postgresql-client-8.2 in Ubuntu. (I recognize that
Ubuntu != Debian. However, this is also a problem in Etch that I just
didn't report earlier, and I think it could be addressed in both distros.)
> $ sudo apt-get install postgresql
> ...
Setting up postgresql-client-8.2 (8.2.7-0ubuntu0.7.10) ...
update-alternatives: unable to make
/usr/share/postgresql/8.2/man/man1/dropuser.1.gz.dpkg-tmp a symlink to
/etc/alternatives/dropuser.1.gz: No such file or directory
^^^^^^^^^^^^^^^^^^^^^^^
The ^^^^ is color-escaped, which is no good for the symlinking.
I think an appropriate solution would be to unset or export
GREP_OPTIONS='--color=none' in the beginning of scripts that rely on grep.
