Just another few data points... I was able to recreate this issue on a CentOS 7 system running in a tmpfs filesystem. So that's pretty much pointing directly at the Linux kernel behavior independent of file system type. Meanwhile... I can also recreate this on a Debian system with a Linux 4.9 kernel in 9 Stretch. But not on 10 Buster Linux 4.19. But once again not on an earlier Linux 3.2 kernel. 3.2 good, 4.9 bad, 4.19 good. Therefore this seems to be a Linux behavior that was the desired way, then flipped to the annoying behavior way, then has flipped back again later. Apparently. Anyway just a few data points. Bob

Gotcha. > $ pwd --version > bash: pwd: --: invalid option > pwd: usage: pwd [-LP] But that is not the GNU Coreutils pwd program. That is the shell builtin pwd. In this case it is bash. And bash does not document either a --version or --help option. $ type pwd pwd is a shell builtin $ help pwd pwd: pwd [-LP] Print the name of the current working directory. Options: -Lprint the value of $PWD if it names the current working directory -Pprint the physical directory, without any symbolic links By default, `pwd' behaves as if `-L' were specified. Exit Status: Returns 0 unless an invalid option is given or the current directory cannot be read. Since this isn't a coreutils program I am going to attend to the housekeeping and close the bug ticket. But please let's continue discussion here for additional questions or comments. This is actually an FAQ. https://www.gnu.org/software/coreutils/faq/coreutils-faq.html#I-am-having-a-problem-with-kill-nice-pwd-sleep-or-test_002e > $ man pwd > > ... > > --version > output version information and exit That is the man page for Coreutils pwd. And if you want to use the external command then you must avoid the builtin. $ type -a pwd pwd is a shell builtin pwd is /bin/pwd $ env pwd --version pwd (GNU coreutils) 8.32 Use of 'env' in this way forces searching PATH for the named program regardless of shell and avoids builtins. Hope this helps! :-) Bob
