By default, LSF only sends you an email with the stdout and stderr included in it, and does not show or store anything locally.

One option to store things locally is to use:

bsub -oo stdout.log -eo stderr.log 'echo myout; echo myerr 1>&2'

bsub -I 'echo a;sleep 1;echo b;sleep 1;echo c'

This immediately prints stdout and stderr to the terminal.
