I need to download files simultaneously- wget doesn't support that so I want to try aria2. But I don't see an option in aria2 to keep directory structure.
Jens A. Koch
Determine the directory structure first, then build and use a download description file:
aria2c -i uri.txt
where uri.txt might contain
http://serverA/file1.iso http://mirror-serverB/file1.iso
# parameters must begin with a space, otherwise it's treatened as url!
dir=/downloads/a
# not mandatory
out=file1.iso
http://serverA/file2.iso http://mirror-serverB/file2.iso
dir=/downloads/b
out=file2.iso
Keep in mind that aria2 is a download util - not an sync util, like rsync or lftp.
