mntfinder

Parse /proc/mounts and find/list mountpoints.

This project IS NOT a wrapper of findmnt.

This project is for Linux-based operating systems only; attempts to install or use on other operating systems (e.g., Microsoft Windows) may result in an error.

Install

Just run the command: pip install mntfinder.

Or you can download and install the wheel file from release page manually.

Examples

List all mountpoints

import mntfinder

for m in mntfinder.getAllMountPoints():
    print(f'{m.source!s} on {m.target!s} type {m.fstype!s} ({",".join(m.options)!s})')

Get a single mountpoint info

import mntfinder

mntinfo_proc = mntfinder.getMountPoint('/proc')
print(f'{mntinfo_proc.source!s} on {mntinfo_proc.target!s} type {mntinfo_proc.fstype!s} ({",".join(mntinfo_proc.options)!s})')

Output:

proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)

Check if a path is mountpoint or not

import mntfinder

print('/sys is a mountpoint:', mntfinder.isAMountPoint('/sys'))
print('/mnt/nonexist is a mountpoint:', mntfinder.isAMountPoint('/mnt/nonexist'))

Output:

/sys is a mountpoint: True
/mnt/nonexist is a mountpoint: False

Check if a mountpoint is alive

import mntfinder
import subprocess

mnt = mntfinder.getMountPoint('/run/media/user/WindowsData')
print(f'{mnt.source!s} on {mnt.target!s} type {mnt.fstype!s} ({",".join(mnt.options)!s})')
print(f'{mnt.target!s} is still mounted: {mnt.isAlive()!s}')
subprocess.run(['udisksctl', 'unmount', '--block-device', mnt.source])  # Unmount the mountpoint by `udisksctl unmount`
print(f'{mnt.target!s} is still mounted: {mnt.isAlive()!s}')

Output:

/dev/nvme0n1p3 on /run/media/user/WindowsData type ntfs3 (ro,nosuid,nodev,relatime,uid=1000,gid=1000,iocharset=utf8)
/run/media/user/WindowsData is still mounted: True
Unmounted /dev/nvme0n1p3.
/run/media/user/WindowsData is still mounted: False

Sorting mountpoints

Maybe useless; no usage scenario found.

import mntfinder

for m in sorted(mntfinder.getAllMountPoints()):
    print(f'{m.source!s} on {m.target!s} type {m.fstype!s} ({",".join(m.options)!s})')
