i am a new user to linux......

i want to implement the following two actions in my server.

1)execute one script which will take backup of "/home/abc" to "/dev/fd0" automatically at a perticular time .

2)execute one script which will keep on monitoring the disk space used in /home partition and if the disk space used reaches 90% it should send a message to regarding this.

Deepak Jena,
Use cron to schedule your tasks, to edit your crontab, type:
crontab -e
to make a copy of the files in /home/abc to /dev/fd0, the command is
cp -r /home/abc /dev/fd0
so to run it each day at 9:00am
your  crontab entry should be:
0 9 * * *  /bin/cp -r /home/abc /dev/fd0

disksize command
 if [[ `df -k /var| grep var |awk '{print $5}' |cut -d% -f1` -gt "90" ]];then /usr/bin/mailx -s Diskfull ;fi

you can run this from cron as above (say evey 15 minutes)
0,15,30,45 * * * * if [[ `df -k /var| grep var |awk '{print $5}' |cut -d% -f1` -gt "90" ]];then /usr/bin/mailx -s Diskfull ;fi
