然后每当您需要超时时，使用

And then whenever you need timeout, use

gtimeout

..相反.要解释为什么这是自制"警告中的摘录:

..instead. To explain why here's a snippet from the Homebrew Caveats section:

注意事项

所有命令都已安装前缀"g".

All commands have been installed with the prefix 'g'.

如果您确实需要使用这些命令的常规名称，则可以 可以从bashrc中将"gnubin"目录添加到PATH中，例如:

If you really need to use these commands with their normal names, you can add a "gnubin" directory to your PATH from your bashrc like:

PATH="/usr/local/opt/coreutils/libexec/gnubin:$PATH"

此外，如果添加，则可以使用普通名称访问其手册页 以及从bashrc到MANPATH的"gnuman"目录:

Additionally, you can access their man pages with normal names if you add the "gnuman" directory to your MANPATH from your bashrc as well:

MANPATH="/usr/local/opt/coreutils/libexec/gnuman:$MANPATH"
