while read line
echo "$line " | grep -i .par$
  if [ "$?" = 0 ]; then
  cd ../par
  echo " Do you want to proceed"

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

You have two read statements, both in a while loop with the input redirected from an input file. Both read statement will get the input from that file. If you want to read from a tty, specify that with:read </dev/tty.
