For details of any of the LSF commands or any other Unix, run man command on the cluster. For example:
[user@hd1 ~]$ man bsub
This will display the man page for the bsub command. Most other Unix commands also have man pages. Note that the man pages are meant to provide a quick reference to users who already have a basic understanding of the command. Beginners looking for a more complete explanation of a topic may be better off finding a good book or tutorial.
The LSF User's Guide is a more complete reference for the LSF scheduler.
The HPC Community website is a gathering place for LSF users. It offers many documents for download as well as a user forum.
