The most recent version of grep is causing problems. If it processes a
file that has a character that is not in the LANG, it stops processing and
outputs "Binary file <name> matches".
This problem came up in building lxqt as the .desktop files have a lot of
characters for different languages. I think these are all utf-8, but I'm
not sure.
There are several ways to work around this problem.
1. export GREP_OPTIONS=--text or it's equivalent GREP_OPTIONS=-a
The man pages says
GREP_OPTIONS
This variable specifies default options to be placed in front of any
explicit options. As this causes problems when writing portable scripts,
this feature will be removed in a future release of grep, and grep warns
if it is used. Please use an alias or script instead.
2. I don't think an alias would be a good option as that would not be
picked up in scripts.
alias grep='grep -a'
3. We could create a script like yacc.
cd /bin
mv grep grep.orig
cat >> grep << EOF
#! /bin/sh
exec /bin/grep.orig --text "$@"
EOF
But there are times when we do not want the --text behavior.
4. export LANG=en_US.utf8 where necessary.
The problem here is trying to pick up all the places where it is
necessary. If a user already has LANG set to a value like fr_FR.utf8, I
don't think it would be needed. It also would not solve the problem if
there are non-utf8 characters in the file being searched.
I'll note that I have already addressed this in
http://www.linuxfromscratch.org/blfs/view/svn/postlfs/cacerts.html
where I had to add export LANG=en_US.utf8 to /usr/bin/make-ca.sh.
For right now, I'm going to go with 4, but am not totally happy with that
solution.
Feedback appreciated.
