I am stuck trying to capture STDERR using &shell().
I am able to capture it using tcsh, but since &shell()
is sh-based, I need some sh-magic to get this working.

  tcsh $ mpinfo -V |& cut -d' ' -f6-8
  10 Mar 2006
  bash-3.00$ /opt/SUNWhpc/HPC6.0/bin/mpinfo -V 2>&1 cut -d' ' -f6-8
  mpinfo: Sun HPC ClusterTools 6 10 Mar 2006 CRE 3.0
  bash-3.00$ tcsh -c '/opt/SUNWhpc/HPC6.0/bin/mpinfo -V |& cut -d" " -f6-8'
  10 Mar 2006

No luck using "tcsh -c" with &shell().

  Value: bogus
  Evaluating: &shell("tcsh -c '/opt/SUNWhpc/HPC6.0/bin/mpinfo -V |& cut -d\"
     \" -f6-8'")
  Replacing vars from section MTT: &shell("tcsh -c
     '/opt/SUNWhpc/HPC6.0/bin/mpinfo -V |& cut -d\" \" -f6-8'")
  --> Prefix now:
