I have the following file
Hello World my name is FalcoGer And I wish to concatenate the strings of each line.
I wrote the following script to do just that.
#! /usr/bin/bash myFile=/home/FalcoGer/testfile.txt result="" cat $myFile | while read line do result+="$line " done echo Result: $result However I only get Result: with an empty string. When I print it from within the loop it seems to work just fine. What's wrong with this script and how do I fix it?

Using the pipe essentially creates a new script with a new scope. You can avoid the pipe like so:
#! /usr/bin/bash myFile=/home/FalcoGer/testfile.txt result="" while read -r line do result+="$line " done < $myFile echo Result: $result
