You can certainly do this visually by repeatedly running a command such as ls -l and comparing file sizes.
通过反复执行 ls -l 等命令并对比文件大小，肯定可以实现这个目标。
The xargs command then takes each process ID (since you used -l 1 to grab one line at a time), and USES sudo kill -hup to send each one a hangup signal.
然后，xargs命令接受每个进程ID(因为使用了- l 1以便一次提取一行内容)，并使用sudo kill - HUP向相应的进程发送一个挂起信号。
If iconv is installed on your Linux computer (which it most likely is), you can determine the available code pages by using the iconv -l command, as shown in Listing 1.
如果您的Linux计算机上安装了iconv(这种可能性很大)，那么您可以使用iconv - l命令查看可用代码页，如清单1所示。
