Re^4: Getting error when trying to compare two files

[adalamre]

Hi, I want to compare all the content and report all differences. Also I am facing some challenge in comparing like when I have captured the content from Linux, it may not match against output from Windows (and vice-versa) since the line ending pattern of Windows would contain a \r\n (That’s a carriage return followed by linefeed) instead of a plain \n in the case of Linux. Please let me know how I can handle these Also can you please let me know how to use Algorithm::Diff

If you feel better at home with external commands, diff is the one you should be looking at.

There are a few options for that. Again if you prefer external commands, look for dos2unix or unix2dos. In Perl, you can substitute with s/\015\012/\012/ - depending on your beforehand knowledge of the size of the files, if they are small, you can treat the whole file in one go or use a while loop to save memory and sacrifice time instead.

can you please let me know how to use Algorithm::Diff

Have you tried using some example from the Algorithm::Diff documentation? Did it produce an unforeseen result?

Again, the question of size may hit you here again. Just for the first go, I'll hope it doesn't ;-)
