under linux Program Console BUG

[Kernelpanic]

- go to a directory and run ls (bash command to list files and directories)

- the command works in the current directory.

The "ls -al" command works even if I specify a different directory; see screenshot.
I am in "~/lab/c" and let me show from there my home directory "~".

But I don't understand the last sentence. I can't really imagine what you mean.
