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

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

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
