Operating Systems HP-UX Old crontab file reflected after server reboot Post 302703853 by ammbhhar on Thursday 20th of September 2012 12:50:16 PM

Hi Vbe,

Thanks for quick reply..
In short u mean I should follow below steps :

1) become the root and take backup of crontab file
e.g : I am user "xyz".Now my crontab file is located in /var/spool/crontabs/"xyz".

2) In order to modify this xyz file I should first become root(how to ,I don't know? I guess our server team will be able to help)
Then I should take backup of this crontab file in my $HOME dir ..say xyz2..

3) Then I should modify the original xyz file (say mod_xyz) .So now I have backup of my crontab file in case something goes wrong.

Please correct me wherever I am wrong. Also,which file out of xyz or mod_xyz will be reflected in crontab after server reboot.

NAME
bcrontab - Manage users crontab files SYNOPSIS
bcrontab [ -u user ] file bcrontab [ -u user ] { -l | -r | -e } DESCRIPTION
bcrontab interfaces with the bcron-spool daemon to manage crontab files in the privileged spool directory. OPTIONS
-u user Tell bcron-spool that we are acting on behalf of the named user. bcron-spool will only accept the username if bcrontab is running as either root or the same user ID as the named user. -l List the cronab crontab to standard output. -r Remove the user's crontab. -e Edit the current crontab. ENVIRONMENT
VISUAL If this is set, it is used as the editor to invoke to edit a crontab. EDITOR If $VISUAL is not set and this is, it is used as the editor to invoke to edit a crontab. If neither are set, /bin/vi is used. BCRON_SOCKET The path to the named socket used to communicate with bcron-spool. Defaults to /var/run/bcron-spool. LOGNAME USER These two variables are used, in order, to determine the user name invoking the program. One must be set if the -u option is not used. FILES
bcrontab tries to writes a temporary file into the current directory, and then into /tmp if that fails, in order to edit the current crontab. SEE ALSO
