Add the following line to the /var/spool/cron/crontabs/owner of testScript.sh file using the vi editor:
0 0 * * * /absolute Path/testScript.sh
The format of this file is six fields: minute (0-59); hour (0-23); day of month (1-31); month (1-12); weekday (0-6,0=Sunday); command to execute. I am not certain of the command syntax.
The crontab search path for can be set in /etc/default/cron file PATH= for user's, SUPATH= for root cronjobs.
Access to the crontab command (used to execute/delete/list cronjobs) is controlled by /etc/cron.d/cron.allow or the /etc/cron.d/cron.deny files (one user per line). Basically a user will be able to use the crontab command if the account is listed in the cron.allow file. By default all initial non-admin accounts are listed in the cron.deny file. If the cron.allow file does not exist users will be allowed access to the crontab command as long as they are not listed in the cron.deny file. Mardio

1. AIX
We recently upgrade from AIX 4.3.3 to AIX 5.3, We noticed that some cronjobs that run for our programmers did not fire off this morning. You can crontab -l and -e and see the jobs. Did AIX 5.3 change something?
Thanks

crontab
CRONTAB(1) General Commands Manual CRONTAB(1)
NAME
crontab - maintain crontab files for individual users (V3)
SYNOPSIS
crontab [ -u user ] file
crontab [ -u user ] { -l | -r | -e }
DESCRIPTION
Crontab is the program used to install, deinstall or list the tables used to drive the cron(8) daemon in Vixie Cron. Each user can have
their own crontab, and though these are files in /var, they are not intended to be edited directly.
If the allow file exists, then you must be listed therein in order to be allowed to use this command. If the allow file does not exist but
the deny file does exist, then you must not be listed in the deny file in order to use this command. If neither of these files exists,
then depending on site-dependent configuration parameters, only the super user will be allowed to use this command, or all users will be
able to use this command.
If the -u option is given, it specifies the name of the user whose crontab is to be tweaked. If this option is not given, crontab examines
"your" crontab, i.e., the crontab of the person executing the command. Note that su(8) can confuse crontab and that if you are running
inside of su(8) you should always use the -u option for safety's sake.
The first form of this command is used to install a new crontab from some named file or standard input if the pseudo-filename ``-'' is
given.
The -l option causes the current crontab to be displayed on standard output.
The -r option causes the current crontab to be removed.
The -e option is used to edit the current crontab using the editor specified by the VISUAL or EDITOR environment variables. After you exit
from the editor, the modified crontab will be installed automatically.
SEE ALSO
crontab(5), cron(8)
FILES
/etc/cron.allow
/etc/cron.deny
STANDARDS
The crontab command conforms to IEEE Std1003.2-1992 (``POSIX''). This new command syntax differs from previous versions of Vixie Cron, as
well as from the classic SVR3 syntax.
DIAGNOSTICS
A fairly informative usage message appears if you run it with a bad command line.
