AFT - Where is Android device mounted automatically on Arch Linux?

Question

Having read this page, I decided to give AFT a try, so I installed it by sudo pacman -S android-file-transfer, connected the device (OnePlus 3T) to the computer through USB, set it to "Transfer files mode", and then opened AFT. So far so good, I see all folders inside my device, I can select files and dowload them. I haven't tried uploading, but I think everythig's ok.

Except that I'd prefer to browse the device in the terminal, so that I can make use of regexp to move stuff from/to the device.

I've found the following

$ ll /dev/disk/by-id
...
usb-OnePlus_Device_Driver_5abf662b-0:0 -> ../../sr0
...

but when I try

$ mkdir mount_here
$ sudo mount /dev/sr0 mount_here

all I see is this

$ ll mount_here
total 18466

Answer 1

Use adb to connect to your device in a CLI.

Prerequisites

Enable Settings > Developer options > USB Debugging on your phone.

Install the drivers.

$ cd mount_here
$ ./adb_config_Linux_OSX.sh

Usage

Check if your device is found by adb:

$ adb devices
List of devices attached
bada5535    device

Now you can browse your device with:

$ adb shell
OnePlus7TPro:/ $ cd storage/self/primary
OnePlus7TPro:/storage/self/primary $ ls
Alarms Android DCIM Documents Download Movies Music Notifications Pictures Podcasts Ringtones

Move files with:

$ adb pull <path>

$ adb push <source-path> <target-path>

Trouble shooting

If you see this message:

$ adb devices
List of devices attached
bada5535    no permissions; see [http://developer.android.com/tools/device.html]

Try to start the adb server as root:

$ adb kill-server
$ sudo adb start-server

If your requirement is

to browse the device in the terminal, so that I can make use of regexp to move stuff from/to the device.

on arch, I found that smple-mptfs in the AUR ( https://aur.archlinux.org/packages/simple-mtpfs/ ) actually works. This provides a single command simple-mtpfs and its man page. If even that is too much to read, here is a self-explanatory script posted by user teckk to the Newbie Corner of the arch wiki ( https://bbs.archlinux.org/viewtopic.php?pid=1729381#p1729381)

#! /usr/bin/env bash

#Script for simple-mtpfs    
PS3=$'\nSelect an option.: '

#mount directory
dir="$HOME/phone"

while :; do
    clear
    options="Quit List_Device Mount Umount"
    select opt in $options; do
        case $opt in
            Quit) clear; exit
            ;;

            List_Device) simple-mtpfs --list-devices
            ;;

            Mount) simple-mtpfs "$dir" -o enable-move; echo "Mounted to "$dir"" 
            ;;

            Umount) fusermount -u "$dir"; echo "Unmounted" 
            ;;
        esac
    done
done

Note that libmtp is a prerequisite for simple-mtpfs, and that the mount point of the above script (default is $HOME/phone) must exist before you run the script.

Spelled out in even more detail: Here is the full set of commands I entered into a terminal (starting in the directory which I use to house AUR packages) to go from "nothing" to satisfying the requirement above:

sudo pacman -S libtmtp
git clone https://aur.archlinux.org/simple-mtpfs.git
cd simple-mtpfs
makepkg -si
#when prompted to confirm install of package simple-mtpfs, type "Y"

#create script droidfile with above text and make it executable

#to mount the phone at $HOME/phone
mkdir $HOME/phone
( echo 3 ; echo 1) |    droidfile

At this point, i can use a coreutils like ls etc and any file manager on $HOME/phone. Note that without the "enable-move" option to simple-mtpfs , you won't be able to use mv. And if you do enable it, it can be very slow.

to unmount, just

(echo 4; echo 1) | droidfile
