NAME
lwp-download - Fetch large files from the web
SYNOPSIS
lwp-download [-a] [-s] <url> [<local path>]
Options:
-a save the file in ASCII mode
-s use HTTP headers to guess output filename
DESCRIPTION
The lwp-download program will save the file at url to a local file.
If local path is not specified, then the current directory is assumed.
If local path is a directory, then the last segment of the path of the
url is appended to form a local filename. If the url path ends with
slash the name "index" is used. With the -s option pick up the last
segment of the filename from server provided sources like the Content-
Disposition header or any redirect URLs. A file extension to match the
server reported Content-Type might also be appended. If a file with
the produced filename already exists, then lwp-download will prompt
before it overwrites and will fail if its standard input is not a
terminal. This form of invocation will also fail is no acceptable
filename can be derived from the sources mentioned above.
If local path is not a directory, then it is simply used as the path to
save into. If the file already exists it's overwritten.
The lwp-download program is implemented using the libwww-perl library.
It is better suited to down load big files than the lwp-request program
because it does not store the file in memory. Another benefit is that
it will keep you updated about its progress and that you don't have
much options to worry about.
Use the "-a" option to save the file in text (ASCII) mode. Might make
a difference on DOSish systems.
