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
exitwill exit, so I could at least check each time before I type it
- how many times I can
exituntil the user is logged out completely
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
