Hi,
Slackware10 kernel 2.4.26
For me unknown reason suddenly bash will not start in terminals.
Do you really mean that the terminal sits open but does not accept any input? Or do you, just possibly, mean that bash starts (you get a prompt and can enter commands) but it does not read its config files the way you expect it to?
Therefore no PSI is set
PS1, perhaps?
and commands I have in ~/.bashrc are not known unless I type bash in xterm after which PSI is set as well.
If you can type "in xterm", then *some* shell is running. If you really don't know what it is, start one up, then use a different one, or a console or remote session, to check the process list to see what shell is running.
BTW, it should also work just to run .bashrc . You might see if it does.
If I open xterm with: "xterm -e su -l"
How are you entering this? Do you mean in another, working xterm?
Are you already root when you do this? As a non-root user, my system will not let me open an xterm with both logging and su ... probably to protect the root password.
I think this works because the bash invoked by su is not a login shell. See below.
it opens with bash, w/o the -l flag there is no bash.
How to resolve?
Is this true for all users or a specific subset of users? In particular, is root different from an ordinary user?
What you are seeing may be differences in behavior between login and non-login instances of bash. A login instance expects to run /etc/profile, ./.bash_profile, ./.bash_login, and ./.profile ... but not ./.bash_rc (though it is not unusual for one of these other files to cause .bashrc to execute).
Overall, what you are describing sounds like a situation where bash is starting but is not getting some fo the settings you want it to have. This may mean a problem in /etc/profile or one of the user-specific bash-login files I listed above.
Without a followup from you, it is hard to be more specific. But all of this, perhaps supported by your reading the man pages for bash and xterm, may be enough to get you to a solution.
Good luck.
