Multi-platform chomp working on unix, windows and mac text files

Question

Looking for a way to chomp newline characters irrespective of the platform the files were created on.

The problem as specified by perlport#newlines is that newlines are encoded differently on each platform:

\012 unix

\015\012 windows

\015 mac

However, chomp is platform specific and will only remove the character for the platform it's running on, or anything set by the $/ variable.

So far I came up with the following regex that seems to be working:

# multiplatform chomp
s/\015?\012?$//;

Is that the correct solution or am I missing some cases and there's a better one?

Answer 1

Why not just use

 s/\s+$//;
