Thanks All. Good feedback. Say i do it via 'at' do you have any command references to hand? maybe an idiots guide thats better than the MAN page? Smilie

It uses the same time specification as touch, so like:

Code:
$ at -f myScriptTemp -t 201309251915
job 2 at 2013-09-25 19:15

...and another for myScriptReal (pick your own, better names Smilie)

Where myScriptTemp swaps in the new cron file:
Code:
crontab tempCrontabFile

And myScriptRead does the opposite:
Where myScriptTemp swaps in the new cron file:
Code:
crontab realCrontabFile

It might just be easier to add a new cron job (one each in the main and temporary files, each replacing the other).

Another idea:
Code:
* * * * * /test/scripts/enabler /test/scripts/1_min_
jobs.sh 1>/dev/null 2>/dev/null
0,5,10,15,20,25,30,35,40,45,50,55
* * * * /test/scripts/enabler /test/scripts/jobs_5mins.sh 1>/dev/null 2>/dev/null
0,15,30,45 * * * * /test/scripts/enabler /test/scripts/jobs_15mins.sh 1>/dev/null 2>/dev/null

And /test/scripts/enabler
Code:
#!/bin/sh
test -f /test/run &&
exec "$@"

Now you can add further cron jobs that create or delete /test/run (or rename to dont_run).
