crond use

aloisius-a · 11-18-2009, 07:42 AM

Hi,
I need to use crond as a normal user, so I looked for a rc.crond file but I haven't found it, and in the same way I haven't found any crond.pid file but I can see, using the command ps, that this pid exists.
Now I am wondering how crond is managed in the Slackware 12.2 distribution, particularly how it is launched and where resides its pid.
can anybody tell me something about this question?

Hi,

The crond daemon starts from rc.M in Slackware

If you want to run a cron job as an ordinary user, just us the command

Code:

crontab -e

to define and edit your crontab entries.
The cron deamon will then start your jobs using your user id at the appropriate time.

Using the man pages for crontab, we can see the following gems :

Quote:

# MIN HOUR DAY MONTH DAYOFWEEK COMMAND
# at 6:10 a.m. every day
10 6 * * * date

# every two hours at the top of the hour
0 */2 * * * date

# every two hours from 11p.m. to 7a.m., and at 8a.m.
0 23-7/2,8 * * * date

# at 11:00 a.m. on the 4th and on every mon, tue, wed
0 11 4 * mon-wed date

# 4:00 a.m. on january 1st
0 4 1 jan * date

# once an hour, all output appended to log file
0 4 1 jan * date >>/var/log/messages 2>&1

That should make it pretty easy to get everything you need out of cron.
