Answer 1

Stuff the above accept for the STARs read about them;
This a REAL BASIC senerio. ASSUMING you are paulb the user
To add a cron job it is BEST to use "crontab"
1) MAKE SURE YOU CAN USE CRONTAB
check "/etc/cron.d/cron.deny " does not exist and it does not have your username in it
If it does, you will have to remove your name somehow or just delete the file.
2) MAKE YOUR SCRIPT
using your fav editor like "joe" or "pico" or err "vi" make a textfile called "home/paulb/hiscript.sh"
This script is just saying hi in sh and then printing a date when it said hi in the dumbhi.log
--------start of hiscript.sh----------------
#!/bin/sh
echo "hi at";date > /home/paulb/dumhi.log;
--------end of hiscript.sh----------------3) MAKE SCRIPT EXECUTABLE
run the command
"chmod +x /home/paulb/hiscript.sh"4) MAKE A CRONTAB FILE FOR YOURSELF
using your fav editor like "joe" or "pico" or err "vi" make a textfile called "home/paulb/paulb.ct"
This is EVERY 1 min run that script. See u need to know the commands
-----start of paulb.ct-------------------------
1  *  *  *  *   home/paulb/hiscript.sh
-----end of paulb.ct-------------------------5) ADD THE CRON JOB
run the command
"crontab /home/paulb/paulb.ct"All done
