The "atq" command is available on many versions of Linux but not in mainstream unix.

So you are not counting Solaris as mainstream Unix? :slight_smile:

Solaris lately has become a weird hybrid. For Solaris commands like this you'd need to qualify whether it is the /usr/bin or /usr/xpg4/bin version.
As it was there in SunOS 4.1.3 we would expect continuity.

Strangely the "atq" command is available in Tru64 Unix but not in HP-UX.

It's there in AIX.
It was missing from Dynix.

Looks like I was wrong. The majority wins.

A common fix for portable scripts if "atq" and "atrm" are missing:
alias atq="at -l"
alias atrm="at -r"
