It's great! Howerer, can it combines a rpc transfer mode so that I can trans tasks to RPC Server？3rd scripts often make some mistakes
Wow, I have finally found the ultimate CLI downloader. I have spent the last day searching for an OS X alternative to the single-threaded wget and curl, that was multi-threaded and would handle HTTPS traffic, and I tried 'em all. I tried puf, which doesn't handle HTTPS at all, axel, which pretends to handle HTTPS but I caught it actually using HTTP instead (tcpdump is your little snitch friend). Naughty, naughty, axel, for giving us a false sense of security… That's worse than no security at all. Then I found the truly amazing aria2. It not only worked first time, right out of the box, handling HTTPS traffic flawlessly (believe me, I checked), but it downloaded files at record speeds--my full allotted bandwidth. I have been looking for a CLI alternative to DownThemAll for Firefox because DTA cripples Firefox and slows the entire system on my pretty fast 8-core Mac Pro. It just struggles to maintain a difficult connection, and I have plenty of those. aria2 handles these with ease and does not in any way slow my system down. The download speed is much more consistent than DTA too--no choppiness like in DTA when it loses the connection for many seconds. It just sits there in the background downloading away at max speed. Wow. Goodbye DTA… I used the following syntax to get these speeds: 'aria2c --file-allocation=none -c -x 10 -s 10 -d "mydir" URL' . Note that aria2c is what HomeBrew has named aria2--don't ask why, I don't know… '--file-allocation=none' speeds up the initialization of the download which can take quite a long time for a multi-GB file otherwise. '-c' allows continuation of a download if it was incomplete the first time. This came in really handy when, for some reason, the speed started flagging and I 'ctrl-c'ed out of the download and restarted it. It resumed right where it left off at max speed. Nice. '-x 10' and '-s 10' give 10 connections per server to speed things along. I suspect the '-s 10' is unnecessary but I prefer to err on the side of overkill. '- d' downloads files to a directory. To install aria2 on OS X, install HomeBrew if you don't have it and then type: 'brew install aria2' To view the huge man page: 'man aria2c'. The above usage is only the tip of the iceberg for this incredible app. I only download one file at a time from normal HTTP(S) URLs but it is capable of downloading multiple files simultaneously from mixed HTTP(S), FTP, BitTorrent, and Metalink sources. And the options are more than anyone can handle in a lifetime. As I said, the man page is huge. No other download client even comes close to the many uses and capabilities of this app. It is truly 'The next generation download utility' (as stated on the home page of aria2 on sourceforge.net). I have only scratched the surface. Kudos to all the devs who labored hard and long to bring this app to fruition and make it available for free to all of us. Great job!
This is amazing software, very fast and useful
