Thank you very much avronius!

Your script worked like a charm.

I just followed your procedure and created crontab and was able to enable and disabled the cron schedule.

Code:

00 11 * * 3 /usr/local/bin/weekselector odd && /usr/local/bin/archTEST/test/even.sh > /usr/local/bin/archbakTST/test/odd_wed.log 2 >&1
00 11 * * 4 /usr/local/bin/weekselector even && /usr/local/bin/archTEST/test/even.sh > /usr/local/bin/archbakTST/test/even_thr.log 2 >&1
#
# This Cron job will be disabled with command
#
20 10 * * * [ ! -f /var/tmp/croncontrol/backup ] && /usr/local/bin/archTEST/test/even.sh > /usr/local/bin/archbakTST/test/100_with_switch.
log 2 >&1

and used your on and off switch command

Code:

$ ./manageCron -e backup  << enable
$ ./manageCron -d backup  << disable

and test output log was created whenever cron was enabled.

My last question will be is there any particular significant to parameter backup ?

I created /var/tmp/croncontrol but "on and off" command really doesn't do anything with backup parameter.

thank you.

endusershell

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME

       getusershell, setusershell, endusershell - get legal user shells

SYNOPSIS

       #include <unistd.h>

       char *getusershell(void);

       void setusershell(void);

       void endusershell(void);

DESCRIPTION

       The  getusershell()  function  returns  a  pointer  to  a  legal  user  shell  as defined by the system manager in the file /etc/shells. If
       /etc/shells does not exist, the following locations of the standard system shells are used in its place:

	 /bin/bash		    /bin/csh
	 /bin/jsh		    /bin/ksh
	 /bin/ksh93		    /bin/pfcsh
	 /bin/pfksh		    /bin/pfsh
	 /bin/sh		    /bin/tcsh
	 /bin/zsh		    /sbin/jsh
	 /sbin/pfsh		    /sbin/sh
	 /usr/bin/bash		    /usr/bin/csh
	 /usr/bin/jsh		    /usr/bin/ksh
	 /usr/bin/ksh93 	    /usr/bin/pfcsh
	 /usr/bin/pfksh 	    /usr/bin/pfsh
	 /usr/bin/sh		    /usr/bin/tcsh
	 /usr/bin/zsh		    /usr/sfw/bin/zsh
	 /usr/xpg4/bin/sh

       The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells.

       The setusershell() function rewinds the file or the list.

       The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells.

RETURN VALUES

       The getusershell() function returns a null pointer on EOF.

BUGS

       All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved.

NOTES

       Restricted shells should not be listed in /etc/shells.
