Top Forums Shell Programming and Scripting sudo command is not working inside a script when placed in cron Post 302286586 by stanleypane on Wednesday 11th of February 2009 01:11:17 PM

It's probably got something to do with the way you have sudo setup to handle passwords. There are a variety of options:

1. sudo will always ask for a password.
2. sudo will only ask the first time it's run
3. sudo will require no password

I'm willing to bet that your script works in your shell because sudo is set to only prompt for a password the first time. When cron calls the script, it is probably hanging waiting on a password to be entered.

I'd look at your /etc/sudoers file to see how you're setup.

Or, you could just put this job into the root crontab and not worry about sudo at all.

NAME
mtailrc - Configuration file for monkeytail DESCRIPTION
A monkeytail configuration uses Apache-style syntax to declare "groups" of files to be tailed. Best explained with an example: <group testgroup> prefix 'server2: ' sudo yes <file> filename /var/log/apache2/access.log prefix 'server1: ' host server1.example.com </file> <file> filename /var/log/apache2/access.log host server2.example.com sudo no </file> </group> OPTIONS
All options can be either put inside a group or file block. Options inside a file block override those in the group block. filename filename filename defines the filename for this block. host remote-host (optional) host defines that this block's file is to be tailed on a remote server. sudo yes|no|1|0 sudo is a boolean specifying whether this file should be tailed as root. This option is supported for both local and remote files (in both cases you will potentially be prompted for your password). prefix "string: " prefix allows you to specify a short string that will be prepended to every line that is displayed for that given file.
