The first five numbers and asterisks are for cron. You don't 'run' that part

If you want to run it with cron, type...

crontab -e

to edit your crontab file and paste the whole line there.

If you want to run it from the command line, remove the * * * * * or 30 15 * * *.

3

are you mean like this?

crontab -e /usr/bin/wget -O - -q "http://example.com/scheduler/cron

how to set time for it?

4

No, just

/usr/bin/wget -O - -q "http://example.com/scheduler/cron"

Sorry, I missed some text in my previous post. Updated.

If you want to run it with cron, type...

crontab -e

to edit your crontab file and paste the whole line there.

The first five fields (* * * * *, etc) tells cron when to run it. You don't need that on the command line.

but i need the server run cron every 10minutes, how to set this?

6

Why didn't you just ask that from the beginning?

man -s5 crontab

7

just for confiramtion
after run
/usr/bin/wget -O - -q "http://example.com/scheduler/cron"

than run

man -s5 crontab

is that correct?

8

No, that isn't correct.

I'm suggesting that you read the manual page for crontab so you can understand what you have to do.

Once you understand it, run crontab -e and add a line to run the job at the desired time.

i.e.

0,10,20,30,40,50 * * * * /usr/bin/wget -O - -q "http://example.com/scheduler/cron"

when running man -s5 crontab

when running crontab -e

what so i do for next step?

Before we go any further I need to know a couple of things.

  1. What are you really trying to accomplish?
  2. Who for (the 'who' can be you, that's OK - but then the question is 'why')?

  1. What are you really trying to accomplish?
    i need to set the url below
    IANA � Example domains
    to run cron every 5 minute

  2. Who for (the 'who' can be you, that's OK - but then the question is 'why')?
    i am webdesign, set for our own company. we dont have programmer, so it hard for me to do it because i have no any knowledge for ssh.

can you list our step by step, thank you very much.:slight_smile:

IMO, you are too stupid to own a computer, so no, I can't.
