UNIX for Dummies Questions & Answers

Hi all,

We use cron "/usr/rdl/sc/cccron" to execute our jobs.
But sometimes it is being changed. but we are not sure when it is changed.

how could we find when cron is modified.

i checked cron by giving ls -l . but it is showing 2009 year.

Code:

ls -l /usr/rdl/sc/cccron
-r-xr-xr-x   1 nassim   rdl        14111 Jun 15  2009 /usr/rdl/sc/cccron

we edit cron with the userid. the user id is test1.

also checked the file

Code:

ls -l /var/spool/cron/crontabs/test1
-rw-------   1 root     rdl          403 Oct 28 14:02 /var/spool/cron/crontabs/test1.

but here it seems oct 28 2011. but i changed this cron with the userid on Nov 15 2011.

Could someone please help?

Thanks & Regards,
Divakar

How did you change it?
A good practice is to put the name of user in the cronfile:

Code:

# @(#)B.11.11_LR     
#  ~vbe/crontab.vbe

above meaning the file is in my home directory called crontab.vbe - if date of this file does not match with the file in /var/spool/cron/crontabs, then someone modified my scheduling (dead easy: just be able to [icode] su vbe; crontab -e [/code] but that doesn't modify MY file... and so I can compare and see what has been changed...

The current active scheduling is always in /var/spool/cron/crontabs...

Hi Vbe,

Thanks for the reply.

we edit the cron by giving "cccron -e userid=test1".

in my system, it is like

I logged in with userid

bash-3.00$ pwd
/users/devp/test1

And couldnt see the cron files in the home directory

bash-3.00$ ls /users/devp/test1 |grep cron
cccron.ccall.norespond
cccron.last

then i typed cron and pressed <tab> key, then following are listed.

bash-3.00$ cron
cron cron.d cronsdo crontab

i couldnt work it out as said by you from the above information.

Could you please help?

Thanks & Regards,
