Binary files comparision

ruby-talk

Hallo guys,
I've got 2 folders with content which I need to binary compare (file by
file). Is in ruby any library to help me with this?
Any other ideas?

Thanks in advance

something like:

cksum1 = `cksum #{file1}`
cksum1.sub!( /(\d+)\s.*/, '\1')
cksum2 = `cksum #{file2}`
cksum2.sub!( /(\d+)\s.*/, '\1')

cksum1 == chsum2

Or is this not what you're after?

regards, Ruud

The FileUtils library includes compare_file(a, b).

In that case why not directly use cmp? I thought the OP wanted a Ruby version.

For small files this could be as easy as

File.read(f1) == File.read(f2)

Marcin, what kind of comparison do you need? Especially what output
do you expect?

Kind regards
