are you sure "ls" is /usr/bin/ls?

  $ type ls
  ls is /usr/bin/ls

I.e., it could be aliased to something weird, e.g. a shell function which
calls '/usr/bin/ls' under the hood but "exit"s in certain cases:

  $ _ls() { /usr/bin/ls ${1+"$@"} | grep . || exit; }

  $ alias ls=_ls

  $ type ls
  ls is aliased to `_ls'

  $ ls
  bin
  file
  home
  ...

  $ ls ENOENT
  /usr/bin/ls: cannot access 'ENOENT': No such file or directory
  logout

Other than that, I don't see how the spawned 'ls' process could lead
to a logout of the calling shell process.

Have a nice day,
Berny

Hi:
    Thank you for your response。

"ls" is /bin/ls

the "/usr/bin/ls" is not exist


Is there any log I can see to find the reason?


Look forward to your reply。

It was a bit hard to find a an old SLES-11.1 ...
Hmm, is your LS_OPTIONS set to something strange?
What if you remove the alias?

Have a nice day,
