Question

有没有办法可以通过bash脚本触发tree.setCellRenderer(customIconRenderer);命令并继续执行bash脚本中的下一个命令而无需等待wget的响应？我正在执行一个命令，该命令应该花费大量时间并且不希望wget保持响应，也不会在超时超时限制后重新触发它

你应该使用--background选项，因为它转到后台并将输出保存到日志中

--background
       Go to background immediately after startup.  If no output file is specified via the -o, output is redirected to wget-log

示例：

$ wget http://cdimage.ubuntu.com/ubuntu-server/daily/current/wily-server-ppc64el.iso --background
Continuing in background, pid 79783.
Output will be written to ‘wget-log’.

$ cat wget-log 
--2015-05-12 11:21:35--  http://cdimage.ubuntu.com/ubuntu-server/daily/current/wily-server-ppc64el.iso

Bash触发器wget命令并且不等待响应，继续执行下一个命令
