《懒人Shell脚本》之十——统计多重路径下的不同扩展名文件及个数

1、统计实现

find -type f | sed -e 's/.*\.//' | sort | uniq -c | sort -n > rst.txt           

2、脚本分解

1) find -type f

regular file , 查找正规的文件

返回:./bak_network/道x网站/bak_第8章.md

b block (buffered) special
 c character (unbuffered) special
 d directory
 p named pipe (FIFO)
 f regular file
 l symbolic link; this is never true if the -L option or the -follow option is in effect, unless the symbolic link is broken. If you want to search for
 symbolic links when -L is in effect, use -xtype.
 s socket
D door (Solaris)           

2) sed -e ‘s/.*.//’

任意字符到. 替换为 空,即取得后缀名           

3) sort

排序           

4) uniq -c

-c, –count 
prefix lines by the number of occurrences 
第一列统计对应的行数           

5) sort -n

compare according to string numerical value

以数字列排序

排序结果为:

1 docx
  2 jar
  2 part
  4 xlsx
  5 rar
  6 PDF
  17 xls
  122 doc
  149 zip
  322 json
  21305 pdf
  154981 jpg
  1559454 txt
 3029912 html
