    Hi guys,

    how can I set a cronjob on the Fedora 7?

    I have written the following command in the /etc/crontab file:

    Code:
    
    SHELL=/bin/bash
    PATH=/sbin:/bin:/usr/sbin:/usr/bin
    MAILTO=root
    HOME=/
    
    
    # php cronjobs
    
    #It starts all saturday at 06:00
    #* 6 * * 6 lynx -dump http://www.example.com/action.php
    
    # The Job starts every day at 05:00.
    #* 5 * * * lynx -dump http://www.example.com/action1.php
    
    # The Job starts every saturday at 04:00
    #* 4 * * 6 lynx -dump http://www.example.com/action2.php
    
    # The Job start every saturday at 24:00.
    #* 0 * * 6 lynx -dump http://www.example.com/action3.php
    
    # The Job starts at 23:00 of each Saturday
    #* 23 * * 6 lynx -dump http://www.example.com/action4.php
    
    # run-parts
    01 * * * * root run-parts /etc/cron.hourly
    02 4 * * * root run-parts /etc/cron.daily
    22 4 * * 0 root run-parts /etc/cron.weekly
    42 4 1 * * root run-parts /etc/cron.monthly
    ~
    ~
    
    but the operations have been repeated many times.
    which is the mistake?

    Was I likely wrong with the time settings and the actions are repeated many times?

    Thanks

    Do not edit /etc/crontab file manually.

    Instead, run the command:

    crontab -e

    and insert the line for your cronjob.

    The problem is the loop.
    Maybe there is an error here:
    * 6 * * 6 lynx -dump http://www.example.com/action.php

    the first asterix are the minutes. To execute it only one time, have I to set this parameter to zero?

    thanks
