Interpreting Shell Script errors when called from CRON

Hi All,

I am calling a series of shell scripts via CRON so everything is running as root. However, in my error log file I am seeing the following errors. Please can anyone offer any advise as to the possible causes and solution to prevent the errors from appearing.

The Error 1227 seems to be called by moving a file from one directory to another but since I am running as CRON and have root permission I am not certain why such an error should be appearing.

The NameVirtualHost *:80 error is cause because I am stopping the web server and then restart it once the whole process has completed.

Not sure what the TERM error or mv: cannot stat errors really mean.

Many thanks for you help.

The log files contains

Code:
[Thu Mar 29 00:45:01 2012] [warn] NameVirtualHost *:80 has no VirtualHosts
ERROR 1227 (42000) at line 5600: Access denied; you need the SUPER privilege for this operation
mv: cannot stat `/home/data/SR1.280312.alpha1.dump.gz': No such file or directory
mv: cannot stat `/home/data/SR1.280312.beta1.dump.gz': No such file or directory
TERM environment variable not set.

Confirm that your scripts work outside cron.
Setup the required enviroment (SHELL,PATH etc.) inside the script.

The error on mv could be that those files reside on NFS share on which local root will not be able to move (with default NFS export options)

Are you able to execute mv on those files outside the script as root ?

That's a MySQL error message. Do you normally access the database as root?

Quote:

The TERM message is coming from Shell because there is no value in $TERM (terminal type). This however means that the program is trying to write or read from a real terminal but cron has no terminal context. This can mean that the program is unsuitable for running from cron or that it requires special parameters when run in background.
