Just Unix基础重温之wc

阅读更多

wc,让我想起当年有个外国记者刁难周总理:“你们中国有多少厕所啊?”

总理云:”一男一女,两个“

呵呵,多么机智的回答。

缅怀总理~~

 

 

wc除了表示厕所以外,还是有其他用处滴~

 

1.wc 用来统计一个或多个文件的行数,词数和字符数

(注:词,指任何以空格、回车、tab结束的字符串)

$ cat daily_log

just for myself

I just love u

end

 

$ wc daily_log

3 8 34 daily_log

3行,8词,34字)

 

 

2.wc还可以用来统计多个文件

 

      $ ls

      daily_log   other

 

      $ wc *

      3   8   34   daily_log

      1   1   1    other

      4   9   35   total

 注:此时wc既单独输出每个文件信息,也输出所有文件总的信息
