bash - How can you redirect a script's output through a process? -

-

i want redirect bash script's output through logging program. specifically, apache's logrotate utility. redirection needs set within script itself.

if redirection done on command line, while executing script, this:

myscript | logrotate -l $logfile.%f 86400 2>&1

here pseudo-code goes inside script accomplish output redirection, not work:

exec >(logrotate -l $logfile.log.%f 86400) 2>&1

you can using named pipe.

pipe=/var/run/myscript/pipe mkfifo "$pipe" logrotate -l "$logfile.%f" 86400 < "$pipe" & exec > "$pipe"

also, regarding 2>&1 redirection -- make sure understand applied. in first example it's applied logrotate, while in second "example" applied script.
