Re: [Help-bash] Fwd: Proper use of nohup within here-document?

[Mun]

Hi Greg,

My here-document looks something like this:

========================================
cat >myScript <<@EOF
#! /bin/bash

date > showMe.txt
nohup gxmessage -timeout 0 -file showMe.txt > /dev/null 2>&1 &

@EOF

chmod 777 myScript
qsub -b yes -sync n ./myScript
========================================

Note the last line with the qsub command.  The whole purpose of the
here-document is to package up a set of commands into a script form
that will be dispatched to another server for execution using a "grid"
tool (aka load sharing facility).

The commands run fine except I can't figure out a way for gxmessage to
not die when myScript exits.

Thanks,
