Top Forums Shell Programming and Scripting How to implement cron job to run my reports dynamically? Post 21353 by usfrog on Wednesday 15th of May 2002 12:17:14 PM

For an exhaustive answer I'd suggest that you give a look at crontab documentation by typing: man crontab

Typically:
crontab -e edits cron jobs on that host and for that user
crontab -l lists existing cron jobs on that host and for that user

FYI the main syntax for setting up a cron job is:
minute hour monthday month weekday command

For instance, to have myScript.sh running Feb-1 at 2:30PM it should be: 30 14 01 02 * /pathToMyScript/myScript.sh

To have the same running at 2:30PM and 2:45PM it would be: 30,45 14 01 02 * /pathToMyScript/myScript.sh

Hope it'll help Smilie

NAME
crontab - maintain crontab files for individual users (ISC Cron V4.1) SYNOPSIS
crontab [-u user] file crontab [-u user] [-l | -r | -e] DESCRIPTION
Crontab is the program used to install, deinstall or list the tables used to drive the cron(8) daemon in ISC Cron. Each user can have their own crontab, and though these are files in /var, they are not intended to be edited directly. If the cron.allow file exists, then you must be listed therein in order to be allowed to use this command. If the cron.allow file does not exist but the cron.deny file does exist, then you must not be listed in the cron.deny file in order to use this command. If neither of these files exists, only the super user will be allowed to use this command. If the -u option is given, it specifies the name of the user whose crontab is to be tweaked. If this option is not given, crontab examines "your" crontab, i.e., the crontab of the person executing the command. Note that su(8) can confuse crontab and that if you are running inside of su(8) you should always use the -u option for safety's sake. The first form of this command is used to install a new crontab from some named file or standard input if the pseudo-filename ``-'' is given. The -l option causes the current crontab to be displayed on standard output. The -r option causes the current crontab to be removed. The -e option is used to edit the current crontab using the editor specified by the VISUAL or EDITOR environment variables. After you exit from the editor, the modified crontab will be installed automatically. SEE ALSO
crontab(5), cron(8) FILES
/etc/cron.allow /etc/cron.deny STANDARDS
The crontab command conforms to IEEE Std1003.2-1992 (``POSIX''). This new command syntax differs from previous versions of Vixie Cron, as well as from the classic SVR3 syntax. DIAGNOSTICS
A fairly informative usage message appears if you run it with a bad command line. AUTHOR
