MacOS – How to Download Parts of the Same File from Different Sources with Curl/Wget

With curl you should be able to do

curl -o customname -r0-499 <url>

where 0 - 500 would be the byte range

curl man page look at the -r option

It is better not to use -O here as the OP would like to specify the destinations. curl -o file.part1 -r0-490000 $url & curl -o file.part2 -r490001- $url – ewindisch

Try

curl -u user:password 'ftp://mysite/%2fusers/myfolder/myfile/raw' -o ~/Downloads/myfile.raw

In FTP URLs, the path is relative to the starting directory (usually your homedir). You need to specify an absolute path, and that means using %2f to specify /. This is needed because the path in ftp: URLs is treated as a list of slash-separated names, each of which is supposed to be given to a separate CWD command. The %2f is decoded after splitting. See RFC 1738 and FTP URLs.

As for the output location, just give a path to -o.

Security suggestions:

• Don't put your password in the URL. Storing it in ~/.netrc is not particularly secure either, but it at least is hidden from ps -ef.

• Your password is sent in clear text. If the server supports it, use curl --ssl-reqd or curl ftps://mysite/...

• Using SFTP (the SSH file transfer protocol) would be even better.
