Re: Function to replace a old file with newer version

There are non-Perl tools to do things like this, rsync for one-way and unison for two-way synchronization.

If you want to do it with Perl, File::Copy and the file test operators together with File::Find should do the trick.

Thanks. I have to do this recursively hence looking for a perl function. I found File::Xcopy update\|UD - copy files only if 1) the file exists in the target and 2) newer in time stamp http://search.cpan.org/~geotiger/File-Xcopy-0.12/Xcopy.pm#xmove($from,_$to,_$pat,_$par)	[reply]

I'm not familiar with unison, but it probably can use recursion. I know rsync definitely does. Use Perl if you want, but it's not the only language that allows utilities to be written that recur through directories. Several utilities already exist which do that.	[reply]
