Run "crontab -e"

doober · 11-24-2003, 06:32 PM

format crontab:

mryellow · 11-24-2003, 06:35 PM

usage: crontab [-u user] file
crontab [-u user] { -e | -l | -r }
(default operation is replace, per 1003.2)
-e (edit user's crontab)
-l (list user's crontab)
-r (delete user's crontab)

And does any of this help juicy. Juicy I'm not for sure. Make a copy of your current one, put it in your cron file, and then import the cronfile

do this:

bash

VISUAL=pico ; export VISUAL

crontab -e

then setup your cron and hit CTRL+X to exit and save it.

fuzebox · 11-24-2003, 06:38 PM

Yes, it will overwrite what is already there (as per what mryellow posted from the help output).

Just use crontab -e and put in new entries yourself.

say you name your crantab file "cron"
then you do: crontab cron

it will overwrite whatever you had there before as long as its the same filename

There's no excuse for not learning the basic vi commands

arial · 11-24-2003, 06:42 PM

crontab -e should do it... this is why cPanel always comes in handy.

Actually it will overwrite it regardless of what the filename is. The file argument you give the crontab command is just for input sake... Your real user's cron data is stored somewhere else on the system, such as /var/spool/cron under most Linux distributions, or /var/cron/tabs under FreeBSD.

Agreed! Should learn VI, or know some of the commands!

Well you can set your editor like goBigtime described above, or...

Read this: http://www-jics.cs.utk.edu/I2UNIX/un...de/node14.html

Basically when you open it you're in naviagtion mode, to enter any text you hit "i" for insert (or "a" for insert after the current letter, "o" for insert on the next line, etc). You type your text, then hit escape to go back into navigation mode. To delete characters, type "x". You can navigate the cursor around with the arrow keys. Once you're done, type ":wq" to (w)rite the file and (q)uit.

Phew.

Tip:

You can add a mailto line at the top and the cron will email you
the output from the scripts. This makes it easier to debug what
this are working and not.
