Redirecting output of background processes after they've been started (BASH)

bigearsbilly · 01-24-2005, 09:04 AM

the closest I've got is:

Code:

ileaf &                            # this usually sigsevs when the xterm exits
exec 2>&1 > log    fg    # need to type it wice

only prob is the xterm dies too!

Hmmm...Seems like the right idea, but I guess having the xterm crash wouldn't be such a good thing. :-)
I appreciate all your posts.

Thanks for your help.

I know this is very late, however decided to post this.

After the program is started in background, lets say with the PID 3798.

ls -l /proc/3798/fd - lists the fd's assigned to the process.

start gdb with: gdb -p 3798
after bunch of output run

p close(1)
p creat("/tmp/foo",0600)
q
y

run ls -l /proc/3798/fd again. You should see /tmp/foo be assigned the fd of 1

Thanks for the reply, however late, ddog123! I haven't looked at this in a long time, but next time I have an excuse to do so, I'll give that a shot. I don't really understand what you're doing, but I'll look into it and post back when I get around to doing so. (Could be a while...)

Again, thanks!
