Bash Script - No file exist in ~/.ssh/

I'm trying to copy a file from: ~/.ssh/ but everytime I run the script it keeps saying

pi@raspberrypi:/etc/greenwich $ ./copybash.sh
cat: ~/.ssh/testfilegen2.log: No such file or directory

copybash.sh

!/bin/bash
sourceFile="~/.ssh/testfilegen2.log"
targetFile="/etc/network/interfaces2"
sudo cat "$sourceFile" > "$targetFile"
sudo service networking restart

Any Suggestions?

Thank you

Take a look to this snippet code:

#!/bin/bash
v1=~/'file1.txt'
v2=~/'file2.txt'
echo 'Hi!' > $v1 
cat $v1 > $v2
cat $v2

$ script.sh
Hi!

The documentation is in the section "Tilde Expansion" of the "General Commands Manual BASH".

Unquote the tilde in the assignment to sourceFile so that it expands properly. Tilde expansion does not occur on parameter expansion.

sourceFile=~/".ssh/testfilegen2.log"

(In this case, no quotes would be necessary at all, but just to demonstrate that the ~ and the following / are the only things that need to remain unquoted for tilde expansion to occur.)
