1. ls 指令
-r 对目录反向排序 -t 以时间排序 -s 在l文件名后输出该文件的大小。（大小排序，如何找到目录下最大的文件） -r 列出所有子目录下的文件(递归) -1 一行只输出一个文件

如图，我们压缩了一个压缩包day4.zip，将这个压缩包传递给other，但是当我们打开之后发现day4.zip下的文件并没有一起传送过去，只传了一个空文件夹day4.zip，解决方式就是要加上一个 ‘-r’
代码语言：javascript代码运行次数：0运行复制zip -r day4.zip day4
cnt=0; while [ $cnt -le 100 ]; do echo "hello $cnt"; let cnt++;done
cnt=0; while [ $cnt -le 100 ]; do touch code${cnt}.c; let cnt++;done
