Hello!
Running this following code:
f = File.open(filename, ‘w’)
f.truncate(10)
f.close
leaves the file filled with 10 zero bytes. Its pretty unexpected,
since the documentation makes no mention of this
(class File - RDoc Documentation).
File.truncate(filename, 10)
works fine, leaving any pre-existing bytes intact. Looking at the
example I assume this has to do with the File#truncate method
expecting me to write some bytes and then truncate them.
Just putting this out there for the next confused person since Google
made no mention of this!
