Package: ksh Version: 2020.0.0+really93u+20120801-9 Severity: normal Output error is not checked for some builtins (at least pwd and ulimit), e.g. after closing stdout.
$ exec >&- $ for i in echo pwd print ulimit; do echo "[$i]" >&2; $i; echo $? >&2; done [echo] 1 [pwd] 0 [print] 1 [ulimit] 0 Note also that for pwd, POSIX[*] says: If an error is detected, output shall not be written to standard output, a diagnostic message shall be written to standard error, and the exit status is not zero. so that one would expect a diagnostic message (and I think that one should also get one for the other builtins).
