I have a shell script which does the encryption of a file where i am passing the file name as a command line argument,but later on the script waits on the screen to enter Y or N
what is the command i should be using on the shell script

#!/bin/bash -x

outfilename=file.out

echo "**********************************" >> $outfilename 2>&1

cd encrypt_files/
"encrypt the file command" $1

read_line $2 ( does this work)
HERE IT WAITS FOR ME TO ENTER Y/N how do i pass it here

echo "*********************************" >> $outfilename 2>&1
