Bug#122817: More food for thought

[Javier Fernández-Sanguino Peña <jfs@computer.org>]

I had this suggestions lying in my INBOX and I believe are worth pointing
out. Even if programs do not rely or depend on an specific environment
being set it is, for sure, a way to enhace the behaviour of many programs.

Also notice that, regarding the complaints made by Bill, that scripts in
profile.d can be forced to be fully POSIX compliant (like we do for
maintainer scripts). Please do not shrug off the idea just because the 
implementations made by other distributions are bash-specific, we can make 
ours non-bash-specific if we wanted to.

Regards

Javier

I'm with you in this. It might help if you show some conveniences the idea 
offers. For example:
==> /etc/profile.d/bash.sh <==
shopt -s checkwinsize


==> /etc/profile.d/colorls.sh <==
# color-ls initialization
COLORS=/etc/DIR_COLORS

if echo $SHELL |grep bash 2>&1 >/dev/null; then # aliases are bash only
  if ! egrep -qi "^COLOR.*none" $COLORS &>/dev/null; then
        alias ll='ls -l '
        alias l.='ls -d .[a-zA-Z]* '
        alias ls='ls '
  else
        alias ll='ls -l'
        alias l.='ls -d .[a-zA-Z]*'
  fi
fi


==> /etc/profile.d/gnome-ssh-askpass.sh <==
SSH_ASKPASS=/usr/libexec/openssh/gnome-ssh-askpass
export SSH_ASKPASS

==> /etc/profile.d/IBMjava.sh <==
echo $PATH | grep -q :/opt/IBMJava2-13/bin: ||\
        export PATH=$PATH:/opt/IBMJava2-13/bin:/opt/IBMJava2-13/jre/bin



==> /etc/profile.d/lang.sh <==
# /etc/profile.d/lang.sh - set i18n stuff

sourced=0
for langfile in /etc/sysconfig/i18n $HOME/.i18n ; do
    [ -f $langfile ] && . $langfile && sourced=1
done

if [ -n "$GDM_LANG" ]; then
    sourced=1
    LANG="$GDM_LANG"
fi

if [ "$sourced" = 1 ]; then
    [ -n "$LANG" ] && export LANG || unset LANG
    [ -n "$LC_ADDRESS" ] && export LC_ADDRESS || unset LC_ADDRESS
    [ -n "$LC_CTYPE" ] && export LC_CTYPE || unset LC_CTYPE
    [ -n "$LC_COLLATE" ] && export LC_COLLATE || unset LC_COLLATE
    [ -n "$LC_IDENTIFICATION" ] && export LC_IDENTIFICATION || unset 
LC_IDENTIFICATION
    [ -n "$LC_MEASUREMENT" ] && export LC_MEASUREMENT || unset LC_MEASUREMENT
    [ -n "$LC_MESSAGES" ] && export LC_MESSAGES || unset LC_MESSAGES

==> /etc/profile.d/less.sh <==
# less initialization script (sh)
[ -x /usr/bin/lesspipe.sh ] && export LESSOPEN="|/usr/bin/lesspipe.sh %s"

if [ x`echo $LANG | cut -b 1-2` = x"ja" ]; then
        export JLESSCHARSET=japanese;
elif [ x`echo $LANG | cut -b 1-2` = x"ko" ]; then
        export JLESSCHARSET=ko;
fi


==> /etc/profile.d/mc.sh <==
mc ()
{
        mkdir -p $HOME/.mc/tmp 2> /dev/null
        chmod 700 $HOME/.mc/tmp
        MC=$HOME/.mc/tmp/mc-$$
        /usr/bin/mc -P "$@" > "$MC"
        cd "`cat $MC`"
        /bin/rm -f "$MC"
        unset MC;
}


==> /etc/profile.d/qt.sh <==
# Qt initialization script (sh)
if [ -z "$QTDIR" ] ; then
        QTDIR="/usr/lib/qt3-gcc2.96"
fi
export QTDIR

==> /etc/profile.d/vim.sh <==
if echo $SHELL |grep bash 2>&1 >/dev/null; then # aliases are bash only
        alias vi=vim
fi

==> /etc/profile.d/which-2.sh <==
# Initialization script for bash and sh

# export AFS, if you are in AFS environment
alias which='alias | /usr/bin/which --tty-only --read-alias --show-dot 
--show-tilde'


Some of those are standard Red Hat, some are mine.

It's a convenience for administrators and developers alike. I wrote bash.sh 
because I want that to be the way _my_ site operates. I fret that IBM doesn't 
have one for Java to its environment variables correctly. A site might one 
for Java so as to set CLASSPATH to point to site-wide Java classes.

Feel free to cite this to push your argument.
