Question: When downloading big files it necessary to pause the download many times. A big file can be downloaded by using `wget`. First start download, then kill `wget`, then resume download by `wget -c`.  

I want to pause downloads too many times depending on events such as power failure, Network unavailability, etc... and want to automate it using a script. So pressing `Ctrl+C` is't an option. I know a process can be paused by `kill -STOP "$pid"` The pausing should not close the connection to the website, either it should wait for resume command or the bandwidth throttled to very low data useage. 

[How to pause aria2 download](https://askubuntu.com/questions/270744/how-to-pause-a-running-aria-download) is a partial solution but option *pause* is not supported in my `aria2` (1.8.0, Ubuntu 10.04 LTS) and I can't upgrade `aria2` (From apt-get install or manually install ). This RPC option for `aria2` seems to works from *Ubuntu 11.10*. So a portable version of `aria2` is also considerable.

**Looking for**  

I'm looking for a download manager which is capable of **throttle bandwidth and pause/resume** all (or one ) the running instance of download upon execution of a `--throttle=10K`, `--pasue` switch or something like that, and resume it on a `--resume` switch (Or using other ways such as RPC). 

I know `killall -9 $(pidof downloader)` should stop all downloads and can be resumed from the last point. But this only a bad choice for me as the number pause/resume is too high and the time to make connection to the server (where download file locate ) is a wastage of time and bandwidth. 

`aria1` can do some job by `--stop` switch. But it's obsolete and solves it partially.

Answer: 
despite you seem to be looking for something very specific, and despite you solved it already, I would still like to recommend `uGet`, I've been using it sindce 12.04 (12.10 64 bits now) and I am very satisfied with the results!
