This is inefficient, I know, but just delete the string, delete the string with a comment, and then add it to the end of the file.

Code:
 
#!/bin/ksh
 
cd /axxhome/prdv/script
if [[ $? -ne 0 ]]
then
   echo "cd error"
fi
for i in *.sh
do
   # look at only 300, 400, and 500 scripts
   if echo "$i" |egrep '300|400|500' > /dev/null
   then
      # delete the string
      sed 's|^\~/bin/chk_env.sh||g' $i > $i.tmp
      # delete the commented string
      sed 's|^#\~/bin/chk_env.sh||g' $i.tmp > $i.tmp1
      # add the string
      echo "~/bin/chk_env.sh" >> $i.tmp1
      # rename when it works
      #mv $i.tmp1 $i
   fi
done

You probably can get by without using the sed command that deletes the string with a comment.

service

service(8)						      System Manager's Manual							service(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
       directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script,  service  passes  COMMAND and OPTIONS it to the init script unmodified.  All scripts should support at least the start and
       stop commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the  start
       command.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

       If the init script file does not exist, the script tries to use legacy actions.	If there is no suitable legacy action found and COMMAND is
       one of actions specified in LSB Core Specification, input is redirected to the systemctl.  Otherwise the command fails with return code 2.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       chkconfig(8), ntsysv(8), systemd(1), systemctl(8), systemd.service(5)
