need to log the execution of script

[nerdhacker]

inside /etc/ppp/ip-up.d i have this script that executes automatically when the interface ppp0 comes up.

#!/bin/sh

echo "Checking if exist internet connection"

ping -c 3 www google com

if [ $? -eq 0 ]; then

  echo "Starting to send & download email"

  echo "Flushing mail queue"

  /usr/sbin/postqueue -c /etc/postfix -f

  echo "Starting fetchmail"

  /usr/bin/fetchmail -v -f /etc/fetchmailrc -L /var/log/fetchmail.log

  echo "Checking mail queue and fetchmail process"

  while ! postqueue -p | grep -q empty && ps -C fetchmail > /dev/null; do

    echo "There is still mail in queue or fetchmail is still working"

    sleep 1

  done

  echo "Terminating the connection"

  killall wvdial

fi

echo "Internet connection not found"

i need to see the output for debug of this script, how can i log this to /var/log/script.log everytime it runs automatically?

You could add >>/var/log/script.log to each line that produces output.

That works, but is cumbersome.

Redirecting stdout/sterr for the whole script may be better

Nice! I knew that was possible but I didn't know how to do it. Thanks for the link!
