Tip 173
Download Files Fuss-Free
Although OS X doesn't include a download manager—a program whose job
it is to take care of downloads, including resuming those that stall or fail—it
does include a similar style of tool at the command line.
CURL
can download
(and even upload) just about any type of file or even entire websites (a process
known as
crawling
).
To use
CURL
to download a large file, open a Terminal window (open Finder,
select the Applications list, and then in the list of applications double-click
Terminal within the
UTILITIES
folder); then switch to the folder into which you'd
like to download the file. This can be done easily by locating the folder in
Finder and then dragging and dropping it onto the Terminal window while
holding down
COMMAND
.
Type
CURL -C - -O
(that's the letter O at the end, not zero), and then drag and
drop from Safari the link to the file you want to download. Note that the link
must directly point to the file and shouldn't be within a password-protected
section of the site—such sites typically rely on cookies to authenticate you,
and those cookies can't be shared with
CURL
.
Once you hit
RETURN
, the download will commence, and you'll be shown a status
display. If the download fails with an error, just repeat the entire command
—this can be done by hitting the Up cursor key and then hitting
RETURN
.
CURL
will resume the download where it left off. Similarly, if the download appears
to stall, which is to say the download speed slows to zero or just a trickle, hit
CTRL
+
C
to abort the download, and then again repeat the command as described
