In [13]: from sh import ifconfig

In [14]: print ifconfig ("eth0 ")
Eth0: flags = 4163 <UP, BROADCAST, RUNNING, MULTICAST> mtu 1500

2. view the files in the/app directory:

In [24]: print sh. ls ("/app ")
Git-2.14.1 myblog pyinit. py v2.14.1.tar.gz

In [27]: sh. ls ("-l", "/app ")
Out [27]:
Drwxrwxr-x 26 root 24576 9 ?. Git-2.14.1
Drwxr-xr-x 6 root 4096 9 ?. 13 myblog
-Rw-r -- 1 root 273 9 ?. 12 20:43 pyinit. py
-Rw-r -- 1 root 6983655 9 ?. 12 20:48 v2.14.1.tar.gz

View the number of files in the/app:

In [28]: sh. wc (sh. ls ("-l", "/app"), "-l ")
Out [28]: 5

3. Save the files in/app to the list:

In [42]: list = sh. glob ('/app /*')

In [43]: list
Out [43]: ['/app/git-2.14.1', '/app/v2.14.1.tar.gz', '/app/pyinit. py','/app/myblog ']

4. MPS queue:

In [45]: print (sh. sort (sh. du (sh. glob ('/app/*'), '-shc'),'-rn '))
397 M ?.?
378 M/app/git-2.14.1
13 M/app/myblog
6.7 M/app/v2.14.1.tar.gz
