Hello Sleep,
A crontab file contains entries for each cron job. Entries are separated by newline characters. Each crontab file entry contains six fields separated by spaces or tabs in the following form:
minute hour day_of_month month weekday command
These fields accept the following values:
minute = 0 through 59
hour = 0 through 23
day_of_month = 1 through 31
month = 1 through 12
weekday = 0 through 6 for Sunday through Saturday
And command a shell command
You must specify a value for each field. Except for the command field, these fields can contain the following:
A number in the specified range. To run a command in May, specify 5 in the month field.
Two numbers separated by a dash to indicate an inclusive range. To run a cron job on Tuesday through Friday, place 2-5 in the weekday field.
A list of numbers separated by commas. To run a command on the first and last day of January, you would specify 1,31 in the day_of_month field.
An * (asterisk), meaning all allowed values. To run a job every hour, specify an asterisk in the hour field.
<b>Crontab parameters:</b>
-e Edits a copy of your crontab file or starts an editing session if you don't already have a crontab file. When editing is complete, the entry is installed as your crontab file. The editing session is started using the editor specified by the EDITOR environment variable. The default editor is vi.
-l Lists your crontab file.
-r Removes your crontab file from the crontab directory.
-v Lists the status of your cron jobs
Examples:
To run the calendar command at 6:30 a.m. every Monday, Wednesday, and Friday, enter:
30 6 * * 1,3,5 /usr/bin/calendar
To run the calendar command every day of the year at 6:30, enter the following:
30 6 * * * /usr/bin/calendar
You can login with ora<sid> user & schedule your job
