DAY=`date|cut -f1 -d ' '`

COUNT=500
export COUNT

export CTR=0

if [ ${CTR} -ge ${COUNT} ]
then
exit
fi
for DAY in Sat Sun
do
INTERVAL=$INTERVAL1
done
/home/mg01800/scripts/send_output.sh
CTR=$(expr ${CTR} + 1)
sleep ${INTERVAL}
done

I agree it should be set as a cron job.

But I think the problem with your script is having "done" in the wrong place.

Code:

export CTR=0

while [ true ]
  do

    if [ ${CTR} -ge ${COUNT} ]
    then
      exit
    fi

    for DAY in Sat Sun
    do
      INTERVAL=$INTERVAL1
      /home/mg01800/scripts/send_output.sh
    done

    CTR=$(expr ${CTR} + 1)
    sleep ${INTERVAL}
              
 done

But I can't figure out why you set interval to 3600 at the beginning, and then overwrite it later on before you do anything with it.

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The  following  default	shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
       /bin/tcsh,  /bin/zsh,  /sbin/jsh,  /sbin/sh,  /usr/bin/bash,  /usr/bin/csh,  /usr/bin/jsh,  /usr/bin/ksh,  /usr/bin/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).

FILES
