how to log everything from a bash script to a file

Hi, I have a menu that support techs will use to start-stop applications, get infos on servers, etc.

I would want to be able to trace everything they do with it.

here would be the bash script:

#################################################################
#!/bin/bash
let "loop=0"
while test $loop == 0
do
clear
echo "Intranet2008"
echo "--------------------------------------------------------------"
echo "a. PROD"
echo "b. PRP"
echo "c. Test"
echo "d. Dev"
echo "--------------------------------------------------------------"
echo "q. Retour au Menu"
echo "Choix?"
read choice

case $choice in q)
let "loop=1"
esac

case $choice in a)
echo "Connexion a PROD"
sh menu-intranet2008-prod.txt
esac

case $choice in b)
echo "Connexion a PRP"
sh menu-intranet2008-prp.txt
esac

case $choice in c)
echo "Connexion a TST"
sh menu-intranet2008-tst.txt
esac

case $choice in d)
echo "Connexion a Dev"
sh menu-intranet2008-dev.txt
esac

done
#################################################################

Do you have an suggestion?

thanks,

Marc

Well, a very quick-and-dirty solution would be to put another echo statement, after the one you already have, like this:

echo "User did this.. at `date`" >> $HOME/shell-script-log-file

This would burp out everything that particular user did, to a log file in their home directory, appending as it went, and putting a date-time stamp on each command.

...and another way could be to use functions plus "logger". With logger you can output to script or syslog. I've taken the liberty to restructure your script a bit. This is easier on the eyes and I hope easier to use and understand or so I hope:

Code:

#!/bin/bash
log() { logger -t scriptname "$@"; echo "$@"; }
display() { echo "Intranet2008, choisir un uhh, choix:"
 select choice in PROD PRP TST Dev Menu; do
 case "$choice" in
  PROD) log "Connexion a PROD"; sh menu-intranet2008-prod.txt;;
  PRP) log "Connexion a PRP"; sh menu-intranet2008-prp.txt;;
  TST) log "Connexion a TST"; sh menu-intranet2008-tst.txt;;
  Dev) log "Connexion a Dev"; sh menu-intranet2008-dev.txt;;
  Menu|*) clear; display;;
 esac; done
} # end display
display
exit 0
