Do you have permission to execute crontab ?

Alternate option.

1. Put the schedule details in a file as like you enter using crontab -e

2. become the user in which you want to execute the cron job. ( su - )

3. crontab .

Verify the permissions of the crontab command:

$ ll /usr/bin/crontab
-r-sr-xr-x 1 root bin 40960 Aug 14 2007 /usr/bin/crontab

The crontab command requires "setuid root" permissions, or else it won't be able to write to directory /var/spool/cron/crontabs. Regular users should not be able to write to that directory using normal tools; only the crontab command should be used to access that directory.

The "setuid root" permission may also be required for notifying the running cron daemon that the crontabs have been modified.

kindly find the file permision.pls advice how to setuid permission

$cd /usr/bin
$ls -ltr crontab
-rwxr-xr-x 1 root bin 28672 Jul 17 2002 crontab

[Patrick Wallek]

$cd /usr/bin
$ls -ltr crontab
-rwxr-xr-x 1 root bin 28672 Jul 17 2002 crontab

That is incorrect. It needs to be fixed!

Do the following:

# chmod 4555 /usr/bin/crontab

Now your crontab commands should work normally and be able to save files as appropriate.

[Shibin_2]

use the command.

# chmod 4555 /usr/bin/crontab
