How can $Now be both less than 705 and greater than 708?
rdcwayx, it sounds like this script is a start/login script that probably runs from .profile. If this is the case, scheduling it to run via cron is unlikley to be usefull.
I think DGPickett is on the right path have your backup (or whatever else is running at 5am Sunday) create a lockfile and check it with the start/login script, that way you can also stop it running for other ad-hoc maintence, or whatever.

Hello all,
I would be happy if any one could help me with a shell script that would determine all the processes running on a Unix server and post a mail if any of the process is not running or aborted.
Thanks in advance

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.
