shell script to tee ITSELF

[Morphine Drip]

greetings all,

I have a shell script that I would like to log to stdout and also to a file.....much like using tee. I would like to, instead of calling the script and piping to tee...i would like for the script to tee itself.

thanks,
drip

rm PIPE1
mkfifo PIPE1
#cat >logfile1 <PIPE1 &
cat <PIPE1 &

rm PIPE2
mkfifo PIPE2
cat >logfile2 <PIPE2 &
#cat <PIPE2 &

rm PIPE0
mkfifo PIPE0
tee PIPE1 >PIPE2 <PIPE0 &

exec 1>PIPE0 2>&1

Um, why go to all that? Just do:

(
# this is a subshell

echo "blah blah blah"
# run whatever else
) | tee /path/to/file in the script.

Probably misunderstanding but 'tee-ing itself': Appart from throwing a bucket of cold water over it how about: tee $0 ??

[bwkaz]

how about: tee $0 ?? Um, feel free to try that, if you don't mind (a) crashing the shell if the script doesn't get cached, and/or (b) destroying the script the first time it runs...

You do not want to overwrite the script with something else... ;)
