I work with Ubuntu 18.04.3

My current directory is /home/hans/bin, The directory /home/hans/.sshz also exist. My shell is "ksh."

The command cd ../.ssh give the output.

ksh cd: /home/hans/ssh:[No such file or directory]

In this command, the . before ssh disappeared. This problem doesn't occur in the sh and bash shells. This problem also doesn't happen in the "ksh" shell on Centos.

Is this a bug in the ksh shell on Ubuntu?

  • Since ksh exhibits the same behavior on my 16.04 I assume it is not a bug otherwise it would have been fixed a long time ago. Seems to be a matter of `../.` because cd-ing to `~/.ssh` works. – xenoid Nov 11 '19 at 16:34
  • Hmm... this seems to be related to the default `FIGNORE` behavior - see for example [ksh regression: with FIGNORE, . and .. are no longer automatically excluded from glob expansions](https://github.com/att/ast/issues/11) – steeldriver Nov 11 '19 at 17:46
