qpeek

When PBS runs a job, the STDERR and STDOUT are written in a private area
on local disk on the master node, and copied back to the files that the user
has specified on the PBS -o and -e arguments.  qpeek allows one to see these
files while the job is running.  Use qpeek JOBNUMBER or qpeek -o JOBNUMBER  
to see the STDOUT,
or use qpeek -e JOBNUMBER to see the STDERR.  See other options by issuing 
qpeek -help
