No output for the command cat sites/default/settings.php

I can see the output for cat sites/README.txt but no output for settings.php

Probably because the file requested doesn't exist.
cat sites/default/settings.php is working fine by default

Try : cat FILE 2>&1

I am about to add this error redirection in the program, so it will always display error messages automatically.
