Thank you for tracking down the root cause! I think that the script should recognize both "-ksh" and "ksh" as ksh. However the script is not part of ksh, it is installed by which. % rpm -qf /etc/profile.d/which2.sh which-2.21-12.el8.x86_64 I am switching the component accordingly. *** This bug has been marked as a duplicate of bug 1768506 *** |
Description of problem: ksh shell invoked as login shell, 'which' command gives error: "-ksh: declare: not found" Version-Release number of selected component (if applicable): ksh-20120801-252.el8.x86_64 How reproducible: Always Steps to Reproduce: 1. Add new user "test" with default login shell as "ksh" # useradd test -s /bin/ksh 2. Switch to user "test" # su - test 3. Execute the "which" command with any binary $ which less Actual results: $ which less -ksh: declare: not found /usr/bin/less Expected results: $ which less /usr/bin/less Additional info: [1] When switching to "test" user, I observed that "echo $0" shows "-ksh" # su - test $ echo $0 -ksh [2] Now when checked /etc/profile.d/which2.sh, observed the if loop only checks for "$0" = ksh" and hence else is executed stating "-ksh: declare: not found" [3] Here is the /etc/profile.d/which2.sh file content: # cat /etc/profile.d/which2.sh # Initialization script for bash and sh if [ "$0" = ksh ] ; then alias which='(alias; typeset -f) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot' else alias which='(alias; declare -f) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot' fi [4] Now when the above file is modified(changed if condition), getting expected results. # cat /etc/profile.d/which2.sh # Initialization script for bash and sh if [ "$0" = -ksh ] ; then alias which='(alias; typeset -f) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot' else alias which='(alias; declare -f) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot' fi
