------------------------


If I run the following job:

# qsub -b y -S /bin/sh '. /usr/local/sge_maintrunk/default/common/settings.sh;
qstat -f'
Your job 1535 ("settings.sh; qstat -f") has been submitted

you can see that the job name is picked up as "settings.sh; qstat -f", which is
pretty useless.  A job named "." is also useless, so we'll have to figure out
what a better solution would be.

This issue is filed as a P5 because the use case that exposes the issue is a
misuse of qsub -b y.  More appropriate approaches include:

qsub -b y /bin/sh '. /usr/local/sge_maintrunk/default/common/settings.sh; qstat -f'

or

echo '. /usr/local/sge_maintrunk/default/common/settings.sh; qstat -f' | qsub -b
y -S /bin/sh

or

qrsh -S /bin/sh '. /usr/local/sge_maintrunk/default/common/settings.sh; qstat -f'

There was already a discussion on the list some time ago, that just all up to and including the rightmost
"/" is removed.

One option could be: if the given argument '. /usr/local/sge_maintrunk/default/common/settings.sh;
qstat -f' is a valid file name, remove all directories and use the filename as jobname (like now for valid
files), otherwise use the string COMMAND (like now STDIN, QRLOGIN or QLOGIN in various cases). If the
user wants something else, he has to specify it with -N in the usual way.
