I logged in to Debian 7 via SSH, not as root
. When writing sudo
all the time became too much overhead, I did sudo su
. Since the Debian default shell (dash
?) does not support the Tab key to complete filenames, I ran /bin/bash
. I added a few aliases to .bash_aliases
and to activate them, I ran /bin/bash
again (potentially a few more times) until I got all aliases right.
After doing some more system setup, I could not remember any more how many times I have to type exit
to get back to the beginning but not logging out from SSH.
Actually this is not a big deal, since I could log in via SSH again, so this is more an academic question. I wondered if there is a way to find out
- what exactly
exit
will exit, so I could at least check each time before I type it - how many times I can
exit
until the user is logged out completely
I tried man exit
but it seems there is no manual available. help exit
doesn't tell much either.
I first thought I could find a possible solution using pstree
, but IMHO it lists sshd
too often and sudo su
is missing.
:~$ pstree | grep ssh
|-sshd---sshd---sshd---sh---bash---bash-+-grep
exit
is a shell builtin. Soman exit
will not work, as there is no man page for it.
