AutoMount partitions using Python in GNU/Linux

I am using various distro of GNU/Linux and I use Ubuntu 9.10,11.04,Fedora 14 and Windows 7(Though I don’t use ,Still I have a partition).

It was boring for me to mount every time I login ,so being Kickass Python fan(decent Python programmer),I tried to write a py script and I succeeded .

Here is the following steps you should perform.

1.Find all Partitions with type.

2.Write a python script which will mount all partitions.

3.Move the python file to appropriate place and start during system start up.

  • Find all partitions with type.

You have to find all the partitions in the system ,most people will think df -T will yield ,yes you are wrong,df -T will yield the partition type of mounted disk only.

You should use sudo fdisk -l

kracekumar@python-lover:~$ sudo fdisk -l

Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Partition 1 does not end on cylinder boundary.

Linux =>Means ext4 partition and some times it may be vfat too,so best way is to mount all the partitions and run df -T to confirm.

kracekumar@python-lover:~$ df -T
Filesystem    Type   1K-blocks      Used Available Use% Mounted on
/dev/sda11    ext4    36990536  15201872  19909624  44% /
none      devtmpfs     1474632       740   1473892   1% /dev
none         tmpfs     1481240      3844   1477396   1% /dev/shm
none         tmpfs     1481240       240   1481000   1% /var/run
none         tmpfs     1481240         0   1481240   0% /var/lock
/dev/sda7     ext4    40551772  36086304   2405492  94% /mnt/ubuntu9.10
/dev/sda9     ext4    20406140   6774300  12595248  35% /mnt/fedora14
/dev/sda5     vfat    32426480  29893680   2532800  93% /mnt/movies
/dev/sda2  fuseblk    85097776  69094072  16003704  82% /mnt/system
/dev/sda6  fuseblk    77869052  64031512  13837540  83% /mnt/others

As we expected sda5 was vfat ,now note down what are the partitions and their type.

Now partitions to be mounted are

#My partions
#/dev/sda6 ->/mnt/others ->ntfs-3g
#/dev/sda2 ->/mnt/system ->ntfs -3g
#/dev/sda7 ->/mnt/ubuntu9.10 ->ext3
#/dev/sda3 ->/mnt/movies ->ext3
#/dev/sda9 ->/mnt/fedora14 ->ext3

Now we are done with the partitions ,in above you can find /mnt/x =>these are the places where partitions to be mounted,so we are suppose to create the directories using sudo mkdir /mnt/x.

  • Write Python script

Command to mount :sudo mount -t type partition destination


sudo mount -t ext4 /dev/sda9 /mnt/somewhere

#! /usr/bin/env python
import subprocess #to execute Linux commands,still you can use os.system but subprocess is preferred
source=('/dev/sda6','/dev/sda2','/dev/sda7','/dev/sda5','/dev/sda9')#partitions to be mounted
dest=('/mnt/others','/mnt/system','/mnt/ubuntu9.10','/mnt/movies','/mnt/fedora14')#destination to mount
type_=('ntfs-3g','ntfs-3g','ext4','vfat','ext4')#type of partition
for (x,y,z) in zip(source,dest,type_):
print x,"is mounted in ",y#confirmation message but when system is started this won't be printed any where.

Now save the file in the name and chmod +x

Now sudo mv /usr/local/bin/

  • Make sure python file is executed during system start process .

Open sudo vim /etc/ ,and add python /usr/local/bin/ before exit 0 which is at the end of the file.

!/bin/sh -e
# rc.local
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
# In order to enable or disable this script just change the execution
# bits.
# By default this script does nothing.

python /usr/local/bin/
exit 0

Above is /etc/rc.local file.

Save the file and restart the system and check.
Download .


Without using Python script you also can auto mount partitions ,but that method is different.
