我想使用以下代码与 aria2c 并行下载多个 torrent 文件：
me@host:~/Downloads$ find . -iregex ".*.torrent" | while read line; do nohup aria2c "$line" &; done
bash: syntax error near unexpected token `;'
解决子shell的问题
me@host:~/Downloads$ find . -iregex ".*.torrent" | while read line; do (nohup aria2c "$line" &); done
nohup: nohup: appending output to 'nohup.out'
appending output to 'nohup.out'
nohup: appending output to 'nohup.out'
nohup: appending output to 'nohup.out'
nohup: appending output to 'nohup.out'
nohup: appending output to 'nohup.out'
nohup: appending output to 'nohup.out'
nohup: appending output to 'nohup.out'
nohup: appending output to 'nohup.out'
nohup: appending output to 'nohup.out'
nohup: appending output to 'nohup.out'
但是所有进程都在停止进程中
me@host:~/Downloads$ ps -aux | grep 'aria'| sed "s/$USER/me/g"

怎么能把它搞定？
