bash is my default shell.
In case of crash, I only loose the commands entered during the session that crashed.
It looks like a normal behavior because cat .bash_history contains only commands typed during the previous sessions while history -a contains commands typed during the current session and history -w the concatenation of both.
Example:
Quote:
santiago@aldebaran:~$ ssh supernova
santiago@supernova:~$ cat .bash_history
echo hello world
santiago@supernova:~$ echo -e "this will appear in the history\nbecause this session will logout properly"
this will appear in the history
because this session will logout properly
santiago@supernova:~$ logout
Connection to supernova closed.
santiago@aldebaran:~$ ssh supernova
santiago@supernova:~$ cat .bash_history
echo hello world
cat .bash_history
echo -e "this will appear in the history\nbecause this session will logout properly"
santiago@supernova:~$ echo -e "this won't appear in the history\nbecause this session will crash"
this won't appear in the history
because this session will crash
santiago@supernova:~$ skill -KILL -u santiago
Connection to supernova closed.
santiago@aldebaran:~$ ssh supernova
santiago@supernova:~$ cat .bash_history
echo hello world
cat .bash_history
echo -e "this will appear in the history\nbecause this session will logout properly"
santiago@supernova:~$ echo -e "this will appear in the history\nbecause I'll save it before crash"
this will appear in the history
because I'll save it before crash
santiago@supernova:~$ history -w
santiago@supernova:~$ skill -KILL -u santiago
Connection to supernova closed.
santiago@aldebaran:~$ ssh supernova
santiago@supernova:~$ cat .bash_history
echo hello world
cat .bash_history
echo -e "this will appear in the history\nbecause this session will logout properly"
cat .bash_history
echo -e "this will appear in the history\nbecause I'll save it before crash"
history -w
santiago@supernova:~$
