$REMOTEHOST is set to NULL on the local machine in csh and tcsh in RHEL 6

Solution Verified - Updated -

Issue

  • $REMOTEHOST is set empty on the local machine in csh and tcsh
  • Its expected that if tcsh can't determine the remote host (or that the user is not actually remote) that it wouldn't set this variable at all.

     $ env |grep REMOTE
    REMOTEHOST=
    $ who am i
    user pts/5        2011-01-07 18:12 (:0.0)
    user@system:log $ env |grep SHELL
    SHELL=/bin/tcsh
    
  • Having it set to "" can break third party applications.
