Description of problem:

When users have /bin/tcsh set as their default shell and log in to a terminal on RHEL 7.7, they receive the message "if: Expression Syntax." before their terminal prompt.  I traced this to an improperly formatted if statement in /etc/profile.d/kde.csh 

if [ ! -d ${HOME}/.local/share -a -w ${HOME} ] then
mkdir -p ${HOME}/.local/share


tcsh appears to error out on the square brackets ( [] ) in this script, as they are not syntactically correct.  A machine kickstarted on 7.2 does not present this error, but one found kickstarted on 7.7 and possibly some other releases between 7.2 and 7.7 appear to have this problem.  I found that the file is provided by the kde-settings package

Version-Release number of selected component (if applicable):
7.7, possibly sooner

How reproducible:
Every attempt, if the improperly formatted /etc/profile.d/kde.csh is present

Steps to Reproduce:
1. set user's default shell to /bin/tcsh
2. log in via SSH or open the terminal
3. alternatively, use "tcsh -l" to start a tcsh login session

Actual results:
Prompt shows the following upon login/running the "tcsh -l" command

if: Expression Syntax.
[user@hostname ~]$ 

Expected results:
User is simply presented with a prompt

[user@hostname ~]$ 

Additional info:
The machine kickstarted on 7.2 has since been updated through all point releases to 7.7 and all releases of kde-settings, but does not have the misconfigured .csh script
