crontab scheduling

[MAYIANAN]

Hi guyz i am very new to crontab kind of scheduling. i need to add a job in crontab.

I tried with crontab -e to edit. It just opens a new line below the command prompt to add the new job. I don know how to save the added one. Also when i enter one job and press enter i get a "?" in next line and the cursor goes to 3rd line. plz let me know how to add a more than one job and save it.

Thx

crontab editing is like a vi editor editing.

If you familiar with vi then edit crontab using command crontab -e

then press "i" then place crontab schedule.If you want to enter multiple jobs simple enter after first job and place another line.

The crontab -e opens your default editor specified by the EDITOR environment variable. Is it vi? And do you know how to use vi?

It also looks like your TERM variable may be wrong and vi starts up in line mode instead of screen mode.

type

echo $EDITOR
echo $TERM

Shalom,

Your .kshrc file will determine such things as how your editor will work.

Take a look at the env for your your shell environment. I imagine some of the basics are missing.

Don't change the root shell in /etc/passwd that can cause crazy things to happen.

Hi,
si mply type crontab and image to have a vi file to save at the end.
To simplify the work I usually use the following crontab template file to start new crontab:

###########################################################

# BACKUP ON ....... ..:.. AM ... - ..: PM server time

# One shot

# minute hour monthday month weekday (0=Sunday) command
# 0-59 0-23 1-31 1-12 0-6
#eof

This will include teh save of teh content of teh crontab itself.

HTH,

You can of course edit your crontab entry externally from crontab -e:
$ crontab -l > cronfile
# edit it
$ crontab cronfile

You'll need to reopen, make sure you assign points, then close.
