Output to console and to log
I have a menu based script where user will select different action via displayed menu.

I want to log all the action or say whatever displayed on screen to a log file and want to achieve with in the same script.

i tried named pipe as below..

Code:
 
logfile=mylogfile
mkfifo ${logfile}.pipe
tee < ${logfile}.pipe $logfile &
exec &> ${logfile}.pipe
rm ${logfile}.pipe

It didnt work out for me.

Could you please let me know any other way to achieve this? may be using exec?Smilie

I am unsure how to use script with in my menu script and start recording all the actions done by the user with that script in a log file?

I tried something like below..

Code:
 
imkfifo out.pipe err.pipe
exec 3>&1 4>&1
tee Menu_`date +"%d-%m-%Y"`.log < out.pipe >&3 &
pid_out=$!
exec  1>out.pipe
tee Menu_`date +"%d-%m-%Y"`.err < err.pipe >&4 &
pid_err=$!
exec  2> err.pipe
rm out.pipe err.
# my script commands here
exec 1>&3 3>&- 2>&4 4>&-
wait $pid_out
wait $pid_err

I remembered have issues using tee with named pipes, but thats long ago since Iused to do those things... That is why I wondered if executing script menu_session.log before the menu wasnt easyer...
