Hello!
Is there a more pythonic way to implement the following program:
8<--------------8<--------------8<--------------8<--------------
#! /usr/bin/env python
import os
import sys
a = os.listdir('/media')
# no mount dirs were found, exit nicely
if len(a) == 0:
sys.exit(0)
# Maybe collecting the arguments via command line
# will make the program more flexible
mnt = open("/etc/mtab")
ptn = open("/proc/partitions")
dskt = '/home/user/Desktop/'
c =[]
# Filling the c with the list of devices which are recorded to be mounted
d = filter((lambda a: a[:2] =='/d'),mnt.readlines()) # non /dev-mounts are
off
d = map((lambda a: a.split()[:1]),d) # only the first info column is used
[c.append(str(a)[2:-2]) for a in d]
# checking against /proc/partitions to see if there're mountpoints without
# corresponding partition which has been removed from the list
# ALL mountpoints with available partition will be removed from the list
x = ptn.readlines()
for a in x[2:]:
b = a.split()[-1]
for d in c:
if b == d.rsplit('/',1)[-1]:
c.remove(d)
if len(c) != 1:
sys.exit(0) # if none or more than one match exit
cmnd = str(c)[2:-2]
err = os.system('umount ' + cmnd)
a = os.listdir(dskt)
#retrieve the info from the KDE desktop icons
for i in a:
if 'desktop' not in i: continue
y = open(dskt + i)
d = y.readlines()
for x in d:
if 'URL=/media' not in x: continue
icon = i
dvc = x[11:-1]
break
err += os.system('rm -f ' + dskt + icon)
err += os.system('rmdir /media/' + dvc)
sys.exit(err)
# if something went wrong exit with high number
8<--------------8<--------------8<--------------8<--------------
I still have a long learnig curve, please give some advise in order to make
the program a bit faster o nicer :)
