[Solved] crontab scheduling
Hi,

We can schedule a new job using
Code:
crontab -e

.
is there any other way to achieve the same(opening the file directly and add an entry).
I have tried to access /var/spool/crontabs directory. But i am getting permission denied error,
Please help me. Thanks

What user ID are you using? Only root can set/edit other user's cron job. Also, there are two file in /etc directory for permitting and denying access to cron job. Those are cron.allow and cron.deny.

Post details please.

I am using my Id only . I am trying to change my scheduled jobs only .
I am able to do this via
Code:
crontab -e

Assuming you are using Linux distro, /var/spool/cron has permission only for root user, others are denied:

Code:
$ ls -ld /var/spool/cron
drwx------. 2 root root 4096 Feb 25 14:06 /var/spool/cron

Use crontab -e. If you are not used to using vi editor, change the EDITOR shell environment variable to whatever editor you like:

Code:
export EDITOR=/usr/bin/nano

All files in /var/spool/cron/crontabs are owned by root...
But nothing is stopping you to:
Code:
crontab -l >my.cronfile
vi my.cronfile #edit and modify to your needs...
crontab my.cronfile

But my intention is to create a shel script and adding new schedules via the scriPt.
It seems it's not possible to achieve that

Paste output of following file:

Code:
 # ls -ld /etc/cron.allow

# ls -ld /etc/cron.deny

Can you edit the sudoers file?

Code:
# visudo
