Cron Command to Run Url Address Every 5 Minutes

CRON command to run URL address every 5 minutes

Based on the comments try

*/5 * * * * wget http://example.com/check

[Edit: 10 Apr 2017]

This answer still seems to be getting a few hits so I thought I'd add a link to a new page I stumbled across which may help create cron commands: https://crontab.guru

Using CRON jobs to visit url?

* * * * * wget -O - http://yoursite.com/tasks.php >/dev/null 2>&1

That should work for you. Just have a wget script that loads the page.

Using -O - means that the output of the web request will be sent to STDOUT (standard output)

by adding >/dev/null we instruct standard output to be redirect to a black hole.
by adding 2>&1 we instruct STDERR (errors) to also be sent to STDOUT, and thus all output will be sent to a blackhole. (so it will load the website, but never write a file anywhere)

cron job to run url cpanel

use this

wget -q -O - http://example.com/backup >/dev/null 2>&1

instead of

wget -q -O /dev/null "http://example.com/backup" > /dev/null 2>&1

Creating a Cron job for URL

Please use lynx text browser (if your server does not have lynx, install it).

then use

 */5 * * * * /usr/bin/lynx https://example.com/?pull-feeds=7b2e9c8d534d6c38ca98c726899b6153 -dump

How to run a cron jobs in every minute for a specific hour on server

To include multiple specific values in a cron job you separate them with commas.

For 16-17 you want 16,17 so you get:

# m |  h  | d | m | Day of week
  *  16,17  *   *   *

# All the below can include multiple values using commas
# m = minute (minute from 0 to 59)
# h = hour (hour of the day, from 0 to 23)
# d = day (day of month, from 1 to 31)
# m = month (month of the year, where 1 is January)
# dow = day of the week (0-7 where 0 and 7 are Sunday)

Run Cron job every N minutes plus offset

To run a task every 20 minutes starting at 5 past the hour, try this:

 5-59/20 * * * *

Explanation

An * in the minute field is the same as 0-59/1 where 0-59 is the range and 1 is the step. The command will run at the first minute in the range (0), then at all successive minutes that are distant from the first by step (1), until the last (59).

Which is why */20 * * * * will run at 0 minutes, 20 minutes after, and 40 minutes after -- which is the same as every 20 minutes. However, */25 * * * * will run at 0 minutes, 25 minutes after, and 50 minutes after -- which is not the same as every 25 minutes. That's why it's usually desirable to use a step value in the minute field that divides evenly into 60.

So to offset the start time, specify the range explicitly and set the first value to the amount of the offset.

Examples

5-59/20 * * * * will run at 5 minutes after, 25 minutes after, and 45 minutes after.

10-59/25 * * * * will run at 10 minutes after and 35 minutes after.

1-59/2 * * * * will run every odd minute.

I need to run cronjob every 5 minutes plus offset time

Following the KISS principle you could just list the minutes
2,7,12,17,22,27,32,37,42,47,52,57

Example:

2,7,12,17,22,27,32,37,42,47,52,57 * * * * curl http://localhost/aa_portal/refresh_id.php
