lwp-mirror - Simple mirror utility
|
||
|
|
|
||
|
|
=head1 SYNOPSIS
|
||
|
|
|
||
|
|
lwp-mirror [-v] [-t timeout] <url> <local file>
|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
This program can be used to mirror a document from a WWW server. The
|
||
|
|
document is only transferred if the remote copy is newer than the local
|
||
|
|
copy. If the local copy is newer nothing happens.
|
||
|
|
|
||
|
|
Use the C<-v> option to print the version number of this program.
|
||
|
|
|
||
|
|
The timeout value specified with the C<-t> option. The timeout value
|
||
|
|
is the time that the program will wait for response from the remote
|
||
|
|
server before it fails. The default unit for the timeout value is
|
||
|
|
seconds. You might append "m" or "h" to the timeout value to make it
|
||
|
|
minutes or hours, respectively.
|
||
|
|
|
||
|
|
Because this program is implemented using the LWP library, it only
|
||
|
|
supports the protocols that LWP supports.
