I am trying to run a script to make a simple modification to a number of similar files. The sed works, but after it runs and the differences are displayed, the script does not read ans to start a renaming script if the user answered Y or y.

Code:

for i in "$@"
do
  sed -f myfile.sed $i >$i.new
  diff $i $i.new
  echo "^[[7my^[[0m to swap files";
  read ans
  case $ans in
   y|Y) setnew $i;;
    *) ;;
  esac
done

The command line is populated by reading in a list via the xargs command.

TIA
