Writing to logfile and stdout

Hi all,
is there a way to simultaneous writing to a logfile and to stdout?
i don't want to use TEE.
the problem is that i open a xterm with option -e to start another process. the output of this process gets to the stdout of the xterm. when the process is finished (it takes up to one hour!) i want to go through the logfile to check for errors but i also want to have the output on the screen. Also tail -f is not what i want because when the process is finished i want to ask for some entries before i finish the xterm.

Is there a reason you couldn't do something like:
print $msgLine print $msgLine >> logfile
The first would print to stdout and the second would print to your log file.
Am I missing something?

You can also use "tee". This will put the output in the file and send the results to SDTOUT.
example:
df -kl | tee myfile

Did you perhaps not notice that the poster indicated the did NOT want to use tee?

Hi, thanks to all for your answer and sorry for my late reply. i was on vacation.
The resason why i can't do print $msg print $msg >> logfile is that i start another automated process which writes to stdout. Unfortunatelly is it not possible to modify this process to write to stdout and logfile.
Maybe somebody knows a perl script or something else which handels the logging process better than UNIX itself does.
Cheers, Mondoshiva

may be you want to try this one.
in your script add this to the begining
LOG=/tmp/process.log
exec 2>$LOG
2 (STDERR) here is used to collect all the errors. by default any process running puts output on 1 (STDOUT).
