I'm writing a simple regression test for a tool like which(1) and someone pointed out there's no guarantee that there is always /bin/sh (AIX seems to have sh(1) as /usr/bin/sh, for example) and we shouldn't try to use it in the test.But we can still say there is always /bin/cat (not /usr/bin/cat or /opt/gnu/bin/cat or whatever,) right? If you are aware of any *nix variant withOUT /bin/cat, please let me know.
Any *nix variant withOUT `/bin/cat`?
