Hi,

For some reason on my gentoo box, if I try to run some processes in the
background, even if they're not trying to print to the console, they block
until I bring them to the foreground. This is only on my gentoo box, every
other Linux/BSD/nix box I work on does not do this, so I'm assuming that it's
some kind of terminal setting.

Would anyone have any idea what would cause this?

Thanks,
Mike

Some examples would be helpful.

echo $SHELL for sure.

It's /bin/bash.

Damn, this actually seems inconsistent. I did a fresh login and background
jobs with output to stdout aren't hanging.

Oh wait, one just did. It started fine...

msoulier@anton:~$ backup_pa.sh &
[1] 15388
msoulier@anton:~$ Backup up remote dirs etc/httpd usr/local/etc git var/www
home/pawsitiveapproach to local file pa_backup.20091107.tar.gz...

msoulier@anton:~$ jobs
[1]+ Running backup_pa.sh &

and then

[1]+ Stopped backup_pa.sh

but if I bring it to the foreground...

msoulier@anton:~$ fg
backup_pa.sh

Hmm, it doesn't seem to be running actually, it looks like it's still
sleeping... All it's doing is running a remote tar over ssh.

My "at" jobs tend to hang for the same reason, but only on that box. I can't
explain it, and I don't know what would control that.
