The first part of the command that you said produces your list of files:
Code:
find /home/ -TYPE

should produce a diagnostic similar to:
Code:
find: -TYPE: unknown primary or operator

and some of the rest of your code seems to be going out of its way to make your life difficult. There is no reason to process the files in each directory separately.

If I understand what you're trying to do, something like the following seems to be a simpler approach:
Code:
#!/bin/ksh
IAm=${0##*/}
searchDir="/home"
searchRE='search string'
rep='replace string'
tmpf="/tmp/$IAm.$$"
trap 'rm -f "$tmpf"' EXIT

find "$searchDir" -type f -name '*.ksh' -exec grep -l "$searchRE" {} + |
while read -r file
do	if sed "s|$searchRE|$rep|g" "$file" >  "$tmpf"
	then	cp "$tmpf" "$file"
	fi
done

Note that I used the pipe symbol (|) rather than slash (/) in case your search pattern or replacement strings are manipulating pathnames. You can replace the pipe symbols with any character other than backslash (\) and <newline>. Try to choose a character that you know will never appear in the search and replacement strings.
