Just add cron job as per your requirements:
13 0 * * * /home/admin/bin/ftpbackup.sh >/dev/null 2>&1
Description:
The cron daemon is a long running process that executes commands at
specific dates and times. To schedule one-time only tasks with cron, use
at or batch. For commands that need to be executed repeatedly (e.g. hourly, daily or weekly), use crontab, which has the following options:
crontab filename
Install filename as your crontab file.
crontab -e
Edit your crontab file.
crontab -l
Show your crontab file.
crontab -r
Remove your crontab file.
MAILTO=user@domain.com
Emails the output to the specified address.
The crontab command creates a crontab file containing commands and
how often cron should execute them. Each entry in a crontab file
consists of six fields, specified in the following order:
minute(s) hour(s) day(s) month(s) weekday(s) command(s)
The fields are separated by spaces or tabs. The first five are
integer patterns and the sixth is the command to be executed. The
following table briefly describes each of the fields:
Field Value Description
minute
0-59
The exact minute that the command sequence executes.
hour
0-23
The hour of the day that the command sequence executes.
day
1-31
The day of the month that the command sequence executes.
month
1-12
The month of the year that the command sequence executes.
weekday
0-6
The day of the week that the command sequence executes. Sunday=0, Monday = 1, Tuesday = 2, and so forth.
command
Special
The complete command sequence variable that is to be executed.
Each of the patterns from the first five fields may either be an
asterisk (*) (meaning all legal values) or a list of elements separated
by commas. An element is either a number or two numbers separated by a
minus sign (meaning an inclusive range). Note that the specification of
days may be made by two fields (day of the month and day of the week).
If both are specified as a list of elements, both are followed. For
example:
MAILTO=user@domain.com
0 0 1,15 * 1 /big/dom/xdomain/cgi-bin/scriptname.cgi
The cron daemon would run the program scriptname.cgi in the cgi-bin
directory on the first and fifteenth of each month, as well as on every
Monday. To specify days by only one field, the other field should be
set to *. For example:
MAILTO=user@domain.com
0 0 * * 1 /big/dom/xdomain/cgi-bin/scriptname.cgi
The program would then only run on Mondays.
If a cron job specified in your crontab entry produces any error messages when it runs, they will be reported to you via email.
You may create crontab files in notepad (being sure to upload them in ASCII) or you may create them from the command line (via SSH) by simply typing:
mcedit cronfile.txt
For more information, consult the man pages. man pages are the directions and tutorials available to you right at the command line. Type any of the following lines to open the relevant tutorials ([Enter] means to hit the Enter (return) key):
man 5 crontab [Enter]
man 1 crontab [Enter]
man cron [Enter]
man at [Enter]
man batch [Enter]
man 1 cron [Enter]
Note:Your crontab file must end with a line feed - in other words, make sure to press [Enter] after the last line in the file.
Try It!
Now that you have read an overview of cron, test your skills by
following the steps below. Once completed, you should have a cron file
of your own!
Step 1: Create a simple text file using Notepad or any simple text editor that contains the following text:
MAILTO=yourusername@yourdomain.com [Enter]
58 23 * * * /big/dom/xdomain/cgi-bin/yourscript.pl
[Enter]
Notes for Step 1
- You may create this file using your CNC
File Manager by navigating to the /big/dom/xdomain/ directory and
clicking 'Create New File' or any other simple text editor such as
Notepad.
- [Enter] should not actually be typed. [Enter] means hit the "Enter"
(return) key to begin the next line and to add a blank line feed at the
end of the last line of your cron file. It is important to always
remember to do this.
- MAILTO: Replace the email address with a valid email address of your
own. This will ensure that when your cron runs, any output from the
script, such as an error message, will be emailed to you.
- The second line tells your server when to run this script. In this
example, the script will be run at 11:58 PM Eastern Time every day of
the year.
- It is very important that you double-check the script path to ensure
it is correct and remember the file names are CaSe-SeNsiTive.
Step 2: Name the text file (example: cronfile.txt).
The cronfile
name may be replaced with any name you choose. For instance, if you are
running a cron to trigger an email reminder script, it could be called reminder.txt. Many choose to simply call it cronfile.txt.
Step 3: Upload the file in ASCII.
Any standard FTP client or your account's CNC upload feature will work for this. The file must be uploaded in ASCII mode and it is recommended that it be placed in your /big/dom/xdomain/
directory. It may be placed anywhere in your account but to prevent
browser access (security risks) it is strongly recommended to place it
above your /www directory.
Step 4: Connect to your account via SSH and issue the following command:
crontab /big/dom/xdomain/cronfile.txt
The above tells the server's crontab where the file is located and
that you wish to make it active. Make sure the path to the file is the
actual path to where the file was placed. If successful, you will be
returned to the command bash line. If not, an error will be displayed.
IMPORTANT NOTES
Removing/Stopping the Cron: Deleting the cronfile.txt file from your account will not
stop the cron. You may remove this file at any time, however since the
server's crontab already has the contents, the cron will still run once
it has been made active.
To turn the cron off, you must connect to your account via SSH and issue the following command:
crontab -r
The crontab -r will deactivate the cronjob and remove the file contents from the server.
Security Note: If the script the cron is set up to
run is in the /cgi-bin/ or /www/ directory, it may be run at any time by
anyone with browser access. If the crontab is all that should run the
script and you do not want the public to be able to run the script, then
you will need to place the script in a directory above the /cgi-bin/
and /www/ directories such as: /big/dom/xdom/user/cronscripts/scriptname
