.IX Title "LWP-DOWNLOAD 1"
.TH LWP-DOWNLOAD 1 "2004-04-10" "perl v5.8.4" "User Contributed Perl Documentation"
.SH "NAME"
lwp\-download \- Fetch large files from the web
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBlwp-download\fR [\fB\-a\fR] <\fIurl\fR> [<\fIlocal path\fR>]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBlwp-download\fR program will save the file at \fIurl\fR to a local
file.
.PP
If \fIlocal path\fR is not specified, then the current directory is
assumed.
.PP
If \fIlocal path\fR is a directory, then the basename of the file to save
is picked up from the Content-Disposition header or the \s-1URL\s0 of the
response.  If the file already exists, then \fBlwp-download\fR 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.
.PP
If \fIlocal path\fR is not a directory, then it is simply used as the
path to save into.
.PP
The \fIlwp-download\fR program is implemented using the \fIlibwww-perl\fR
library.  It is better suited to down load big files than the
\&\fIlwp-request\fR 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.
.PP
Use the \f(CW\*(C`\-a\*(C'\fR option to save the file in text (ascii) mode.  Might
make a difference on dosish systems.
