Cron job fails, but works fine from command line

Shell Programming and Scripting
1

I have a very basic script that essentially sends a log file, via FTP, to a backup server. My cron entry to run this every night is:

55 23 * * * /usr/bin/archive_logs

The script runs perfectly when executed manually, and actually worked via cron for about three weeks. However, it mysteriously stopped working. I removed the entry from cron, re-added it. I even changed the time in the cron entry and tried it again. It still won't run from cron, but, again, works like a champ when I run it manually.

Below is the script:

#!/bin/sh
DAY=`date +%m%d%y`

#Copy log to /tmp and add timestamp
cp /archive/logs/sys/alarm.log /tmp/alarm.log.$DAY

#Send file to webservers
cd /tmp
ftp -n 123.45.678.90 << !
user xxxxxxxx yyyyyyyy!
cd Developers/VMSMSP/Archive/MSP/MSPWASH
put alarm.log.$DAY
!

#Cleanup
cd /tmp
rm alarm.log.$DAY

Any ideas?

Redirect it's output to a file to see what's happening, ie.:

55 23 * * * /usr/bin/archive_logs > /tmp/archive_los.tmp123 2>&1

I tried that, but when I take a look at archive_los.tmp123, it is empty.

Any chance that it is due to not having a full path? As I recall cron does not normally set up the entire environment including path data.
