Command in a for loop

[bluetick]

I'm capturing video from security ip cameras. The error logs and video for each delay any return from each command so I have added the & to continue to the next for loop. Running the script from the command line, it works but will not exit to a clean prompt. Thanks for any help, I'm streching the noob bubble =)
capcam ()
{
rm ${LOGS}/*CAM.log
for X in ${ADDIES} ;do
exec ${CAPTOOL} ${CAP_OPT1} http://${X}/mjpg/video.mjpg ${CAP_OPT2} ${STORE}/${X}.$ROT.avi > ${LOGS}/${X}CAM.log &

done
}

Why do you use that 'exec'.? sh says:
exec [command [arg ...]]
Unless command is omitted, the shell process is replaced with the
specified program (which must be a real program, not a shell
built-in command or function). Any redirections on the exec com-
mand are marked as permanent, so that they are not undone when
the exec command finishes.Your 'exec ${CAPTOOL}' replaces the current shell process with ${CAPTOOL}. That is the cause of your problem. Just get rid of that 'exec'. ;)

An example of the other use of exec, which make the redirects permanent:$ cat exec.tst
#!/bin/sh

# redirect standard output to file 'output'
exec >output

# redirect standard error to standard out, and
# thus to file 'output'
exec 2>&1

# --- These statements need no redirects anymore
echo A
echo B
echo C >&2

$ ./exec.tst
$ cat output
A
B
C
$
