对于MacOS(Mavericks),我正在制作一个
shell脚本,以便随着时间的推移收集传输统计信息,用于命令dd.
手册页面说：
If dd receives a SIGINFO (see the status argument for stty(1)) signal,
the current input and output block counts will be written to the
standard error output in the same format as the standard completion
message.
因此,就像在Linux中,我试过：
kill -INFO <pid_of_dd>
这似乎对我有用：
