View Full Version : [ubuntu] cron tab help ?
November 21st, 2008, 05:25 AM
currently my command my line in crontab is like this:
01 01 * * * perl /usr/local/awstats/wwwroot/cgi-bin/awstats.pl -update -config=www.mydomain.com
this is to update
I would like to update it to schedule every 5 minutes? how do I do that? Just wanted to confirm I am doing this right, crontab newbie.

From 'man 5 crontab':
Step values can be used in conjunction with ranges. Following a range with ‘‘/<number>’’ specifies skips of the number’s value through the range. For example, ‘‘0-23/2’’ can be used in the hours field to specify command execution every other hour (the alternative in the V7 stan‐ dard is ‘‘0,2,4,6,8,10,12,14,16,18,20,22’’). Steps are also permitted after an asterisk, so if you want to say ‘‘every two hours’’, just use ‘‘*/2’’.
So */5 in the minute field seems to be what you want.

so this is right ?
05 * * * * perl /usr/local/awstats/wwwroot/cgi-bin/awstats.pl -update -config=www.mydomain.com
how about the rest of the command, is that ok ?

0-55/5 should work also

This is the whole thing:
*/5 * * * * perl /usr/local/awstats/wwwroot/cgi-bin/awstats.pl -update -config=www.mydomain.com
