Why my shell script not working with cron?

Question

I have two shell scripts .

( working one )

$ cat script_nas.sh

#!/bin/bash
for i in `cat nas_filers`
do echo $i
  touch /mnt/config-backup/nas_backup/$i.auditlog.0.$(date '+%Y%m%d')
  ssh -o ConnectTimeout=5 root@$i rdfile /etc/configs/config_saved > /mnt/config-backup/nas_backup/$i.auditlog.0.$(date '+%Y%m%d')
done

other

( not working one )

$ cat script_san.sh

#!/bin/bash
for i in `cat san_filers`
do echo $i
  touch /mnt/config-backup/san_backup/$i.auditlog.0.$(date '+%Y%m%d')
  ssh -o ConnectTimeout=5 root@$i rdfile /etc/configs/config_saved > /mnt/config-backup/san_backup/$i.auditlog.0.$(date '+%Y%m%d')
done

Cron entries are:

$ crontab -l
Filers config save script
0 0 * * * /mnt/config-backup/script_san.sh
0 0 * * * /mnt/config-backup/script_nas.sh
0 0 * * * /mnt/config-backup/delete_file

Script script_san.sh is not working. Outputs are like SAN backup directory

san_backup]# ls -lart alln01-na-exch01a.cisco.com.auditlog*
-rw-r--r-- 1 root root 210083 Mar  1 22:24 alln01-na-exch01a.auditlog.0.20150301
[root@XXXXX san_backup]# pwd
/mnt/config-backup/san_backup

NAS backup directory

nas_backup]# ls -lart rcdn9-25f-filer43b.cisco.com.auditlog*
-rw-r--r-- 1 root root 278730 Feb 26 00:06 rcdn9-25f-filer43b.cisco.com.auditlog.0.20150226
-rw-r--r-- 1 root root 281612 Feb 27 00:17 rcdn9-25f-filer43b.cisco.com.auditlog.0.20150227
-rw-r--r-- 1 root root 284105 Feb 28 00:02 rcdn9-25f-filer43b.cisco.com.auditlog.0.20150228
-rw-r--r-- 1 root root 284101 Mar  1 00:02 rcdn9-25f-filer43b.cisco.com.auditlog.0.20150301
[root@XXXXXXX nas_backup]#

From cron logs I can see that cron is executing both the script but output for script_san.sh is not coming.

Answer 1

From my experience, most of the times script is working manually but not from crontab is because login scripts were not running. Try to add something like source ~/.bash_profile in the begging of script or first line in cron file. Did you try (for debugging) to run the script with at command?
