Read in script doesn't work
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

Not sure I understand. Is there some context missing? What do you mean by "command line is populated by reading in a list via the xargs command"? Is stdin - which read would read from - redirected to somewhere or coming from the terminal / user keyboard?
User e.g. lsof from another terminal to find out.

It was originally something like:
Code:
xargs <fileLocationList myScript

I think you are correct that stdin wasn't available from the keyboard.

In a later test, I prepended the script name and a space on fileLocationList and made it executable. After running "fileLocationList" the script paused to read and process ans.

Thanks for looking at it.
