Text File Synchronization

by Anonymous Monk
on Oct 09, 2003 at 00:12 UTC ( [id://297772]=perlquestion: print w/replies, xml ) Need Help??

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks, I have two text files in different directories. I constantly have to update the two files. Is there a way to have a perl script to read both files and synchronize one with the most recent one? Thank you!!!!!

    If they serve the same purpose, then would it be possible to just use one file? I'm thinking of the adage, "A man with one watch always knows the time. A man with two is never sure."

    Otherwise, I think we need to know a bit more about the files to know how to handle certain issues. For example, what if they're config files and File A has one setting and B has another? How would you want to synchronize that?

    This should be pretty platform independant. 

    perl -mFile::Copy=copy -e" copy @ARGV[ -s $ARGV[0] > -s $ARGV[1] ? ( 0
+, 1 ) : ( 1, 0 ) ]" \path\to\file1 \path\to\file2
