weird cron job issue

[leaonow]

hi guys
i wrote a piece of code to back up my wiki data file from fedora to my windows xp

#!/bin/bash
working_directory=/root/scripts/cron
source=/root/wiki/
target=wiki.`date '+%y%m%d'`.tar
remoteadd=//192.168.198.1/r
mountpoint=/root/Rmount/
winuser=administrator
mypasswd=password
log=/root/scripts/cron/backupwiki.log
mount_error=1
copy_error=2
mount_flag=0
copy_flag=0
cd $working_directory
echo "Hello-------------------------------------------`date '+%y%m%d'`">>$log
mount.cifs $remoteadd $mountpoint -o user=$winuser%$mypasswd>>$log
mount_flag=`echo $?`
echo "$mount_flag">>$log
if [ $mount_flag -eq 0 ];then
  echo "Mount successfully"
else
   tail -2 backupwiki.log
   echo "bad mount">>$log

 echo "BadBye------------------------------------------`date '+%y%m%d'`">>$log
   exit $mount_error
fi
tar -czvf $target $source&&cp $target $mountpoint
copy_flag=`echo $?`
if [ $copy_flag -eq 0 ];then
  rm -rf $target>>$log
  umount $mountpoint>>$log
  echo "Backup successfully"
  echo "GoodBye-----------------------------------------`date '+%y%m%d'`">>$log
  exit 0
else
  umount $mountpoint>>$log
  rm -rf $target>>$log
  echo "Copy problem"
  echo "Copy problem">>$log
  echo "BadBye------------------------------------------`date '+%y%m%d'`">>$log
  exit $copy_error
fi

this script works perfectly if i run it manually
but it failed if run by cron job (as root user)

[root@MYSERVER cron]# crontab -l
00 */1 * * * rdate -s time-b.nist.gov
37 13 * * * sh  /root/scripts/cron/backupwiki.sh

the error log is following

Hello-------------------------------------------080907
127
bad mount
BadBye------------------------------------------080907

the file structure is

[root@MYSERVER cron]# ls -l
 8
-rwxrwxrwx 1 root root  236 09-07 13:37 backupwiki.log
-rwxrwxrwx 1 root root 1199 09-07 13:00 backupwiki.sh

anyone has any idea about error code 127 for mount.cifs?

i spend couple of hours to figure out but just have no clue at all.......
plz give a hand on this

thanks and regard

Don't use cronjob, I put my scripts in /etc/cron.daily

Check my sig for scripts, works well for me.

hey marcrblevins, thanks for ur quick response, well i am not able to access ur site,
and the key thing here is, i need to know the same script
why works perfectly if run manually
but give error under a cron job

cheers

Put in the full path of mount, umount, & tar in your script. That is a wild guess.
If you use mount.cifs, got to use umount.cifs as well, not umount.

Use these

/sbin/mount.cifs
/bin/tar
/sbin/umount.cifs

u r the man,marcrblevins
thanks alot dude
one question following is
the path for root(take it from /root/.bash_profile)

PATH=$PATH:$HOME/bin:$ANT_HOME/bin:$JAVA_HOME/bin:$J2EE_HOME/bin:$JBOSS_HOME/bin
:/sbin/

why the script not able to fetch the /mount.cifs since i already include it /sbin/ in the path.....

thanks in advance

Found this link:
http://linuxgazette.net/151/prestia.html

Copy/Pasted from the link:
PATH
Because cron runs as subshell process, we need to either specify a path or use a PATH statement in crontab. The reason for this is that we are not logging into a console when we run these jobs - so neither .bashrc or .bash_profile have been sourced, and we have no environment variables to work with as we do when we login as a regular user or as root. It's also important to remember that trying to output data without a console is pointless - there's no screen to display it on! - so you need to make sure that any output that you want to save is logged somewhere.

cool mate, it's really helpful
the reason i print to console is for debugging

yeah,the problem is resolved,thanks again marcrblevins
