The man page of qquota states in the FILES section to have files like $HOME/.sge_qquota to allow default arguments to qquota. This is not working. E.g. putting a plain:

\-u *

inside yields:

error: ERROR! invalid option argument "*"

It's the same for any username. On the command line it's working though.

qrsh is documented to accept -o and -e, and probably shouldn't be. It silently accepts and ignores -o (presumably also -e).

Scripts which use /bin/ksh should be changed to use /bin/sh to be more portable and to stop rpmbuild adding a ksh requirement.
