Rish is an Interactive SHell for android
rish is an Android program for interacting with a shell that runs on a high-privileged daemon process.
Currently, Shizuku and Sui are two available backends.
First of all, follow the guide from Shizuku or Sui to create the files of rish.
The remain is very simple, you only need to replace sh with rish in the command you want to run, rish will pass arguments directly to the remote shell.
Here is an example.
rish -c 'ls'
This is what will be executed at remote:
/system/bin/sh -c 'ls'
If you want to use other shells rather than /system/bin/sh, use rish exec /path/to/other/shell.
Since rish passes arguments directly to the remote, rish uses environment variable for options.
| Value | Description |
|---|---|
0 |
Do not change environment variables of the remote process |
1 |
Replace the environment variables of the remote process with local's |
Termux app set PATH and LD_PRELOAD to Termux's internal path.
Adb (Shizuku can run under adb) does not have sufficient permissions to access such places, making users can even not using commands like cd.
If the backend runs under adb, RISH_PRESERVE_ENV will be treated as 0 when not set.
If the backend runs under root, RISH_PRESERVE_ENV will be treated as 1 when not set.
