Shell scripting in the Android environmentXakep article in the magazine for those who are not able to master more or less serious text for sane people - a waste of time

teamset -x- the debugging tool built into the shell, displays each script command instderr, the details.
wShell- terminal emulator with web interface based on Shell In A Box. If the Android device and the computer are on the same local network, you can access the command line of the device from a computer via a web browser.
Shellcheck- static analyzer (lint) for shell scripts (few details)

Most commands and scripts hosted in this thread are executed as root. This means that a command (or script), if used improperly, can create new problems and not help solve old ones. And the problems are already big, before which the old ones will seem to be a mere trifle.
Therefore, before you rush to download, drive commands and execute them
1. Make a full backup of the firmware (nandroid backup).
If you do not know what it is, you are in this topic too soon. Read the help sections for newbies on the forum, the theme of the firmware of your device.
"Toy" backups, such as Titanium Backup will not help, if something terrible happens. The backup manager bu built into Android ICS and higher (used by programs like Helium) will also not always help. Do not indulge and do not be lazy, make a normal backup from under the recovery.
2. Made in paragraph 1 backup put in a safe place.
Do not delete it immediately after your experiments have ended, in your opinion, successfully. Android can have a completely different view on their success. Watch the system, live some time in it. If you see strange things, roll back to the saved state. Watch again.
By the way, backup will help and analyze what happened, if something suddenly happens. We may need files from it during the trial.
3. If you don’t understand at all what a particular script does, laid out in the subject, still try to figure it out before you use it.
For some scripts it is necessary to comply with the conditions of their execution, otherwise they will not only not work, but also do something with the system. Easily.
Surely the script as it is laid out will not suit you. You will need to "finish" it to fit your needs.
Finally, the worst (and the most unlikely, but still). You may slip the script that will do something bad. And okay, if simply the files in the system wonders, you performed item 1 of the rules. (True? Exactly sure? Ok, let's believe.) Worse, if the script sends something to a short number in Zimbabwe. Well, there is a credit card, for example. What, no credit cards? Nothing, SMS for a short number in Zimbabwe is not free, you know. And do not think that something will protect you, the script from the root does not catch any antivirus or various security managers. Of course, we will quickly intervene, and the further spread of malware will stop. (But specifically your SMS will leave. In Zimbabwe.)
4. Your device (phone, tablet) is not the only testing ground for your experiences.
Most of the scripts can be checked and debugged on the BB under Linux. Virtual machine and Live distribution is enough. Any Linux distribution. It will take busybox to bring such a polygon closer to the real machine, but in any Linux distribution box, busybox is present.
You can also use the Android emulator. Yes, there is a Google on the farm and such. Lies next to the SDK for Android, an image with Android can be found on the Internet. This is anyway better than killing a real device. I remind you that it cost you a certain amount. (Of course, working in the emulator you are already tired of step 1 of the Rules. You do not need to follow these rules.)
5. For debugging scripts it is better to use not a terminal emulator application, but adb (Android Debug Bridge) or ssh session From BB to the device.
Fingers will break typing characters on the virtual keyboard. Again, make a mistake, make mischief. The client part of adb (for BB) can be found on the Internet, the server part in Android already exists (do not forget to enable debugging in “Settings”). Applications with ssh server can be found on Google Play.
