Default -bash: no job control in this shell

Hi Gurus!

When I boot my debian sid workstation:

I usually log into tty1 and then run startx. But sometimes i noodle around at the command line,
say to update drivers for X or whatever, run emacs, etc.

I notice right after I initially login to the pc

the shell says to me (ominously):

-bash: no job control in this shell.

1) I don't know what this means.
2) I don't know what causes it.
3) It bothers me (I dont know why. Just in principle!).
4) So if I really want that job control thingy back, what do I have to do.

I figure it is a left over from some mess up of my . files. But Professor Google
has not clued me in to know what causes this.


Thanks!
Mitchell

Perhaps some command in your .bashrc or .bash_profile. You can
some echo lines to see which command... (or "set -x", but this
will give you a lot of output).

I have the same problem on a vendor install testing partition running
amd64. I searched for the answer for weeks before asking on the and64
list and not getting an answer. Odd that it's only on tty1.

I get rid of the "-bash: no job control in this shell" by logging in
and then doing a ^c. It logs that shell out and doesn't return on the
next login.

I've been installing Debian for years and have never seen this before.
Sure would like to figure this out so let me know if you do.

It means you can't hit CTRL-Z to suspend a process, move processes to
the foreground and background, or use the jobs command. See the JOB
CONTROL section of bash(1) for more details.

Not sure what causes it, but I always (and only) see it when I boot
for emergency recovery with "init=/bin/sh".

> 2) I don't know what causes it.

It may have something to do with your terminal.

It's fairly harmless, but very annoying, especially if you get stuck
and need to kill something.

> 4) So if I really want that job control thingy back, what do I have to do.

Depending on what's caused it to break, you could look at your
terminal configuration, try using the "set -m" command to turn job
control back on, starting up another shell, or using screen(1).

To find out, create a brand new user with default dotfiles, and try
logging in as that user.

Hope this helps,

----Scott.

Sorry, but this list is not the right place for support. The gentoo-user
mailing list is what you want.
