I'm trying to use
umask -S to show the current mask in symbolic form (per
man umask on my system, which gives me the page BASH_BUILTINS(1)). But
umask doesn't seem to behave as the manpage claims:
user$ umask 22 user$ umask -S umask: Improper mask. user$ umask -p umask: Improper mask. user$ which umask umask: shell built-in command.
I'm running this in
csh on RHEL 6.9. Something like
umask 022 works fine. Why would the behavior differ from the manpage?
