How do I specify > an arbitrary queue to "at"? Just add a similar line to this file. cat-ing /usr/bin/batch reveals a shell script. As it is probably considered source code, I cannot show it here ;-) but you specify different queues to at by saying "at -qA" where A is [a-z]. This is how it is done here anyway.... -- Jim Webb "Out of phase--get help" ...!ihnp4!hropus!jrw "Make sure comments and code agree. If not, write a man page..."
