Yes, we can help you do that, but we need some examples
ie. input and expected output.
control file name control.ctl:
Code:
value=1 value=32
value7=a value7=b

Code:
for file in *.txt
do
      while read old new
      do
          sed "s/$old/$new" "$file" > tmp
          mv tmp "$file"
      done < control.ctl
done

This will not always work, especially when you try to replace what are regex metacharacters.
