Thanks for your review and the tip. If I understand correctly the
diff
command would be "diff -u old new" or you need some more switches in
general to the diff command (for example: diff -Naur)?
diff -u is sufficient to diff 2 individual files.
The other letters in the often used -Naur are:
* -r = recursive, should always be used when diffing directories (i.e. use
diff -ur as a minimum in that case).
* -N = includes files which are only in either of the 2 directories,
treating them as added or removed. Needed if you added or removed any files,
but unwanted if one directory has object files, executables or some other
generated files and the other does not.
* -a = includes all files, even if diff thinks they're binary. Usually a bad
idea (especially if there are object/executable files or other such
generated binaries in your directories), but sometimes diff might think a
file is binary when it isn't really (e.g. because it's an FSF text file with
"form feed" characters in them (I haven't seen anybody else use form feeds
for years, but the FSF still uses them for some reason)).
