Can sort these out into their own issues/articles later:

• Template .bashrc location: /etc/skel/.bashrc

• Discover non-essential processes on login:

  alias proclist='ps -eo user,pid,ppid,pcpu,pmem,stat,start_time,etime,cmd --sort=-pcpu,-pmem \
  | egrep -v "  0.[0-9]  0.[0-9] " \
  | egrep -v "auditbeat|metricbeat|vscode|gnome-shell|desktop|firefox|slideshow" \
  | egrep -v " [0-9]  0.[0-9]" \
  | egrep -v "rsync|polkitd|sftp-server|notty|screensaver|mmfsd|atom"'

• Terminal direct messaging:

  user=...; for term in $(w $user | grep $user | awk '{print $2}')
      do echo "Please do not run jobs on the login node.\nPlease contact support@listserv.uab.edu for assistance." | write $user $term
  done
