Python Learning-Print the most commonly used 10 Linux commands and find duplicate files in directories

First, print the most commonly used 10 Linux commands

#!/usr/bin/python#coding=utf-8import osfrom Collections Import Counterc = Counter () with open (Os.path.expanduser (' ~/. Bash_history ') as F:for line in f:cmd = Line.strip (). Split () if Cmd:c[cmd[0]]+=1print C.most_common (10)

The effect is as follows:

Second, find the duplicate files in the directory
