Description of Problem:

/etc/profile.d/which-2.sh set alias for all shells executing the script, not
just bash. All other scripts under /etc/profile.d set aliases only for bash.

Version-Release number of selected component (if applicable):

which-2.12-3

How Reproducible:

Always.

Steps to Reproduce:
1. Execute the script under ksh/zsh/...

Actual Results:

Alias is set.

Expected Results:

Alias is not set.

Additional Information:
	
Use this script instead:

if echo $SHELL |grep bash 2>&1 >/dev/null; then # aliases are bash only
# Initialization script for bash and sh
alias which='alias | /usr/bin/which --tty-only --read-alias --show-dot --show-tilde'
