please don't 'piggy-back' threads - start a new thread for the new unrelated question.
also it would be considered a good tone to know if any of the posted solutions were applicable/useful.

You should have started a new thread rather than continue on an old one.

Try this.

Code:
while read line
do
KEY=$(echo $line | awk '{ print $1 }')
VALUE=$(echo $line | awk '{ print $2 }')
sed -n -e 's/'$KEY'/'$VALUE'/g f_name > f_name.tmp
mv f_name.tmp f_name
done < ren

Not tested tho'.

vino,
you have mis-balanced single-quotes in your 'sed'. Plus single-quotes will prevent shell variables from being expanded.

The idea from the previous question can be applied here as well - not tested
Code:
sed 's/^\([^ ][^ ]*\) *\([^ ][^ ]*\)$/s#\1#\2#g' ren > /tmp/ren.$$
sed -f /tmp/ren.$$ fname > newFname
rm /tmp/ren.$$
