Python reads all files in a directory and subdirectories
I am trying to translate this bash line into python:
find /usr/share/applications/ -name "*.desktop" -exec grep -il "player" {} \; | sort | while IFS=$'\n' read APPLI ; do grep -ilqw "video" "$APPLI" && echo "$APPLI" ; done | while IFS=$'\n' read APPLI ; do grep -iql "nodisplay=true" "$APPLI" || echo "$(basename "${APPLI%.*}")" ; done
As a result, you will see all video applications installed on the Ubuntu system.
-> read all .desktop files in / usr / share / applications / directory
-> filter strings "video" "player" to find video attachments
-> filter the string "nodisplay = true" and "audio" to not show audio players and applications without gui
The result I would like to have (for example):
kmplayer
smplayer
vlc
xbmc
So I tried this code:
import os
import fnmatch
apps = []
for root, dirnames, filenames in os.walk('/usr/share/applications/'):
for dirname in dirnames:
for filename in filenames:
with open('/usr/share/applications/' + dirname + "/" + filename, "r") as auto:
a = auto.read(50000)
if "Player" in a or "Video" in a or "video" in a or "player" in a:
if "NoDisplay=true" not in a or "audio" not in a:
print "OK: ", filename
filename = filename.replace(".desktop", "")
apps.append(filename)
print apps
But I have a problem with recursive files ...
How can I fix this? Thanks to

It looks like you are looping wrong os.walk()
. There is no need for a nested loop.
For a correct example, refer to the Python manual:
https://docs.python.org/2/library/os.html?highlight=walk#os.walk
for root, dirs, files in os.walk('python/Lib/email'):
for file in files:
with open(os.path.join(root, file), "r") as auto:
