Though I also have "simple-mtpfs" installed I'm mostly using it with the SD cards mounted read-only. For "real" work I'm using "adb" provided by "dev-util/android-tools". Among many other things like pushing files to or pulling files from your mobile phone, it provides a "shell" sub-com- mand which allows executing a single shell command on the mobile device or opening a shell on it for issuing more commands in a row: $ adb shell herolte:/ $ cd /storage/emulated/0 herolte:/storage/emulated/0 $ ls -ld . drwxrwx--x 27 root sdcard_rw 4096 2024-05-16 08:01 . herolte:/storage/emulated/0 $ touch xxx herolte:/storage/emulated/0 $ ls -l xxx -rw-rw---- 1 root sdcard_rw 0 2024-05-16 16:13 xxx herolte:/storage/emulated/0 $ mkdir yyy herolte:/storage/emulated/0 $ ls -ld yyy drwxrwx--x 2 root sdcard_rw 4096 2024-05-16 16:13 yyy herolte:/storage/emulated/0 $ rmdir yyy herolte:/storage/emulated/0 $ rm xxx herolte:/storage/emulated/0 $ cd /storage/5BC5-805B herolte:/storage/5BC5-805B $ ls -ld . drwxrwx--x 7 root sdcard_rw 32768 2024-02-21 20:20 . herolte:/storage/5BC5-805B $ touch xxx herolte:/storage/5BC5-805B $ ls -l xxx -rwxrwx--x 1 root sdcard_rw 0 2024-05-16 16:14 xxx herolte:/storage/5BC5-805B $ mkdir yyy herolte:/storage/5BC5-805B $ ls -ld yyy drwxrwx--x 2 root sdcard_rw 32768 2024-05-16 16:15 yyy herolte:/storage/5BC5-805B $ rmdir yyy herolte:/storage/5BC5-805B $ rm xxx herolte:/storage/5BC5-805B $ exit Three additional remarks: - The mobile phone is not required to be rooted. - But to get "adb" working requires "USB Debugging" to be enabled on the mobile device. On your mobile device this option can be found under "Settings -> Developer Options" (if the "Developer Options" are still hidden in the "Settings" menu, make them visible once and forever by opening "Settings -> About Device -> Software Information" and tapping "Build Number" seven times). - For security reasons (for instance when charging your phone at a pub- lic charging station) you should only enable "USB Debugging" on your own phone while connecting it with your own computer for file transfer or similar work.
