Full Discussion: Date command does not work in a KSH when called from Cron
Top Forums Shell Programming and Scripting Date command does not work in a KSH when called from Cron Post 302312588 by devilsadvocate on Saturday 2nd of May 2009 02:22:17 AM

But the script works correctly from the command line, and the date command is executed as expected. e.g. if i run it from command line on 30th april, the condition Date +%d -d tommrrow != '01' is false and script executes further. But when it is called from the cron on 30th april, this condition becomes true because 'date +%d -d tommorrow' returns 30 instead of 01.


Why would the same command that returns 01 on the command line will return 30 when called from cron ?

30

BTW. Solaris crontab does support 'day-day' 'hour-hour' syntax.

yum-cron

yum-cron(8)															       yum-cron(8)

NAME

       yum-cron - an interface to convieniently call yum from cron

SYNOPSIS

       yum-cron [config-file]

DESCRIPTION

       yum-cron  is  an  alternate  interface to yum that is optimised to be convenient to call from cron.  It provides methods to keep repository
       metadata up to date, and to check for, download, and apply updates.  Rather than accepting many different command line arguments, the  dif-
       ferent functions of yum-cron can be accessed through config files.

       config-file  is	used  to optionally specify the path to the configuration file to use.	If it is not given, the default configuration file
       will be used.  It is useful to be able to specify different configuration files for different use cases.  For  example,	one  configuration
       file  might  be set to update the repository metadata, and a line could be added to the crontab to run yum-cron frequently using this file.
       Then, another configuration file might be set to install updates, and yum-cron could be run from cron using this file just once each day.

FILES

       /etc/yum/yum-cron.conf
       /etc/yum/yum-cron-hourly.conf

SEE ALSO

       yum (8)

AUTHORS

       See the Authors file included with this program.

BUGS

       There of course aren't any bugs, but if you find any, you should email
	the mailing list, yum@lists.baseurl.org, or consult bugzilla.
