vi中执行shell命令
vi中执行shell命令在vi中也可以执行shell的命令。在line mode下执行指令!command， command 是 shell 命令。例如指令 !date 会把目前的时间和日期显示到屏幕上。
要是你想把 shell 命令的结果放到文件中，可以用 r !command。比如 r !date 会把现在的时间插入到游标所在行的下一行。可以指定行数，例如 20r !date 会把現在的时间放到第二十一行。
如果你想要执行一连串的的 shell命令但又不想离开vi，你可以在line mode下指令sh。这个指令会建立一个 shell，如果要离开，按【 ctrl-D 】，或者执行exit命令。
你也可以选择文档中的文字作为 shell 命令的输入。输出的结果会替换掉你输入的文字。例如 2,5!sort 会把第二列到第五列的文字依序排列，而原来的文字就会被覆盖。
