Environment

Release : 9.3 and 9.4

Cause

This is caused by a change made to the system file /etc/profile.d/which2.sh on RHEL 8.

Starting in RHEL 8 the which2.sh sets bash functions for 'which'

The error occurs due to installing the one or both the following packages:
scl-utils 
environment-modules 

Resolution

The following can be used as work around.

Add the following to the $AW_HOME/site/sosite file. Once added, the Applications Manager process will need to be stopped, and sosite needs to be run before before restarting for the change to take effect.

unset ${which_opt} which

unset which_declare

Additionally, the following single command can be used:

unset -f $(env | grep -oP "^BASH_FUNC_\K([^%]*)")
