The real problem it looks like you were facing is reading "number" and then trying to pass it to the variable "$x" I've corrected that in the code below. The "-n" switch for echo doesn't terminate the command with a new line. I changed "file" to "file.txt" because there is a "file" command on linux, which your script would append to if it was run in the same directory as find. It would be a good idea to write a check into your script, for the existence of the file you wish to append to. -- Kent

#!/bin/bash

echo -n "Enter a number: "
read number
echo a >> file.txt
echo b >> file.txt
echo "$number" >> file.txt
