I have the below crontab job that it will run at every 7:00am - 10:00am , it work fine , now if I want to skip to run the crontab job at a specific time , eg. I want the script not to run at next Monday 8:00am ( only skip this time , other time is normal ) , how can I make it ? is it possible ? thx in advance .

00 7-10 * * * script

use at command to instruct your server to stop crond one minute before next Monday 8:00am and restart crond at 8:01am, or make your script to kill itself if it is "Monday 8:00am"

good luck

Your crontab should look like something like this

Code:

0 7-10 * * 0,2,3,4,5,6,7  script

The time columns is:

Minutes 0-59
Hours 0-23
Day of month 1-31
Month 1-12
Day of week 0-6 (0 == Sunday by default)

then it will do nothing on every monday !

try this at the beginning of your script:

Code:

#!/bin/sh
day=`date | awk '&#123;print $1&#125;'`
time=`date | awk '&#123;print substr&#40;$4,0,2&#41;&#125;'`
echo $time
if &#91; $day = "Mon" &#93;; then
  if &#91;$time = "08" &#93;; then
    exit
  fi
fi

excuse me for my bad scripting, but that should give you some ideas, you might want to check for date as well

good luck

And that's exactly whats wanted, right? It was just this particular script that was not supposed to be started each monday,

Code:

0 1 * * * script1
0 2 * * 0,2,4 script2

This crontab will run script1 every day at 1:00 am,
and script2 every Sun, Tue, Thu at 2:00 am.

Just to fast I was, saw a flaw in my prev example,
should have been:

Code:

 0 7-10 * * 0,2,3,4,5,6 script

The last 7 would be erreneous

my understanding is the cron should only skip next Monday's 8:00am, the rest of the Monday 8:00am is not included.... hmm....

whatever...

Could be, I might have missunderstand the context of the question.
Even so, there are a few solutions here now.
