Backup with shell program and cron job.

Hi,

The object of my program is to take automatic backup on daily basis to different folders. I have created the respective folders. when I execute below given shell program manually it is working perfectly and taking the backup to respective folder.

#!/bin/sh
#script to take backup on day basis, This is going to run from cron job.
#
while :
do
clear
yourch=`date +%u`
case $yourch in
1) exp backuser/backuser@linux1 file=/disk4/backup/Mon/linux1_Mon.dmp log=/disk4
/backup/Mon/linux1_Mon.log full=y direct=Y compress=N rows=N; exit 0;;
2) exp backuser/backuser@linux1 file=/disk4/backup/Tue/linux1_Tue.dmp log=/disk4
/backup/Tue/linux1_Tue.log full=y direct=Y compress=N rows=N; exit 0;;
3) exp backuser/backuser@linux1 file=/disk4/backup/Wed/linux1_Wed.dmp log=/disk4
/backup/Wed/linux1_Wed.log full=y direct=Y compress=N;rows=Y exit 0;;
4) exp backuser/backuser@linux1 file=/disk4/backup/Thu/linux1_Thu.dmp log=/disk4
/backup/Thu/linux1_Thu.log full=y direct=Y compress=N rows=N; exit 0;;
5) exp backuser/backuser@linux1 file=/disk4/backup/Fri/linux1_Fri.dmp log=/disk4
/backup/Fri/linux1_Fri.log full=y direct=Y compress=N rows=N; exit 0;;
6) exp backuser/backuser@linux1 file=/disk4/backup/Sat/linux1_Sat.dmp log=/disk4
/backup/Sat/linux1_Sat.log full=y direct=Y compress=N rows=Y; exit 0;;
esac
done

When the same program kept in cron, it is not working.
IF I EXECUTE NORMAL COMMAND IN THE CRON WITH OUT SHELL THEY ARE WORKING WHEN I KEEP ANY SHELL PROGRAMS, THEY ARE NOT WORKING.

0 23 * * * /home/oracle/backup/backup.sh
> /home/oracle/backup/backup.log

The backup.log file is creating with 0 bytes.

Please help me in solving this problem.

With Regards
Varma.

it helps if you list the errors you get when it is run via cron.

most likly it is your env settings.

do a search on the boards for cron and env we get questions of this nature pretty offten.
