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

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

I want to compare all the content and report all differences. If you feel better at home with external commands, `diff` is the one you should be looking at. 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 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 ;-) Cheers, Sören Créateur des bugs mobiles - let loose once, run everywhere. (hooked on the Perl Programming language)	[reply] [d/l]
