Bal - A Tool to Synchronize Document Collections Between Computers
The enormous growth of computer networks and declining hardware
prices allow people to have more than one computer, e.g., to use a
primary computer at work, a laptop or notebook as a secondary computer
for 'on the road' and maybe a third computer at home.
trivial problem that users face when using more than one computer
alternately is the difficulty of keeping multiple, distributed copies
of their files up to date and in sync, if they can't permanently share
resources between their machines, e.g., when using a notebook computer
off-line for some time.
System administrators of Unix sites who
need to automatically distribute files between machines have known
such problems for years and have come up with various tools to solve
their specific needs. But tools which help Unix administrators are not
always adequate for their users too.
This paper describes
Bal, a tool which enables Unix users to more easily keep
distributed copies of their files in sync. Bal is written in
Perl and keeps two directory trees in sync.
