−	A jobscript can be used to submit the job you wish to execute to a ~~batch system~~. It is very similar to a [[sh-file]] and generally uses the same format, but is more powerful. Besides shell commands, you can use so-called magic cookies, e.g. #BSUB for [[LSF]] systems.

 Depending on your batch system, these pages provide more information on how to use magic cookies in your jobscript: [[LSF#.23BSUB_Usage|LSF]], [[SLURM#.23SBATCH_Usage|SLURM]], [[Torque]].
-One advantage of jobscripts is that the parameters that are prefixed with magic cookies are treated like comments. So you can run your jobscript as an [[sh-file]] without the [[scheduler]] and if that works, still adjust and correct the lines with magic cookies destined for the [[scheduler]].
