actually, it is only ubuntu doing this by default. even debian lenny has bash
as /bin/sh (although, of course, one should never rely on sh==bash,
especially on machines running on commercial unix variants). therefore when
relying on bash features (such as reading .bashrc), one should explicitely
write #!/bin/bash and not #!/bin/sh into the job scripts.
in case the queuing system does not call jobscript not directly, but instead
forces /bin/sh as an interpreter, set the appropriate job options to use
/bin/bash instead (in torque, this is job option '-S').
