Raspberry Pi Pushbutton Shutdown/Startup

This is extracted from a single post by user RonR in a thread about FreePBX for the Raspberry Pi on DSLReports. I though it might be useful to many Raspberry Pi users:

Raspberry Pi Pushbutton Shutdown/Startup

The attached script will install shutdown and startup capability using a SPST NO momentary pushbutton
switch connected to GPIO header pins 5 and 6. Pressing the button on a running system will initiate
a graceful shutdown (shutdown -h now). Once shut down, pressing the button will restart the system.

1. Copy install and gpio-shutdown.dtbo to the Raspberry Pi.

2. Make the install script executable:

$ chmod +x install

3. Run the install script:

$ sudo ./install

4. Reboot

For additional info, see:

The script can be downloaded from RonR’s original post or directly from https://www.dslreports.com/r0/download/2324182~6a03744946c51bfa4876b6ecd8d4528c/PushButton.zip

How to Pass Arguments to a Bash-Script

You can write a bash script such that it receives arguments specified when the script is called from the command line. This method is used when a script has to perform a slightly different function depending on the values of input parameters (the arguments).

For example, you may have a script called “stats.sh” that performs a particular operation on a file, such as counting its words. If you want to be able to use that script on many files, it is best to pass the file name as an argument, so that you can use the same script for all the files to be processed.
