9 lwp-download [-a] [-s] <url> [<local path>]
10
12 The lwp-download program will save the file at url to a local file.
13
14 If local path is not specified, then the current directory is assumed.
15
16 If local path is a directory, then the last segment of the path of the
17 url is appended to form a local filename. If the url path ends with
18 slash the name "index" is used. With the -s option pick up the last
19 segment of the filename from server provided sources like the Content-
20 Disposition header or any redirect URLs. A file extension to match the
21 server reported Content-Type might also be appended. If a file with
22 the produced filename already exists, then lwp-download will prompt
23 before it overwrites and will fail if its standard input is not a
24 terminal. This form of invocation will also fail is no acceptable
25 filename can be derived from the sources mentioned above.
26
27 If local path is not a directory, then it is simply used as the path to
28 save into. If the file already exists it's overwritten.
29
30 The lwp-download program is implemented using the libwww-perl library.
31 It is better suited to down load big files than the lwp-request program
32 because it does not store the file in memory. Another benefit is that
33 it will keep you updated about its progress and that you don't have
34 much options to worry about.
35
36 Use the "-a" option to save the file in text (ascii) mode. Might make
37 a difference on dosish systems.
