Multiple scripts in one single script - crontab
Hello all,
Hope all's well.

i'm not sure if this is possible but i have some scripts running in a crontab with different intervals, 1min, 5 min, etc.

As for a "cleaner" and better control of these scripts (as by time we will have hundred's of scripts used for the same purpose, i.e for Nagios monitoring), i was wondering if these scripts can be integrated in a master script, let's say we call it Master_cron.sh.
This master script will run every minute but, here's my dilemma, the scripts inside will still need to run with different time intervals. Do you think this can be achieved somehow?
i was thinking maybe i can use the date/time command
Code:
date +%T

to set the script to run in intervals, but am not sure i'm in the right track.

Was thinking maybe i can use an indefinite loop something like:
Code:
while sleep 1m
do
    script 1 running every 1 minute, script 2 running every 1 min, etc.
    ....
done
while sleep 5m
do
    script 1 running every 5 minuts, script 2 running every 5 min, etc.
    ....
done

For using the while am not sure if the above is a correct syntax

Note that of course i need to be careful since these scripts run in the root cron, so i cannot overwrite the root cron. The OS is Solaris 10.

Thanks in advance.

crontab

CRONTAB(1)						      General Commands Manual							CRONTAB(1)

NAME

       crontab - maintain crontab files for individual users (ISC Cron V4.1)

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 ISC 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 cron.allow file exists, then you must be listed therein in order to be allowed to use this command.  If the cron.allow file does not
       exist  but  the	cron.deny  file does exist, then you must not be listed in the cron.deny file in order to use this command.  If neither of
       these files exists, only the super user will be allowed 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.
