But top has one advantage over ps it updates its display every couple of seconds, so you can see how the resource usage changes in almost real-time.

or just brute force restarts until the program runs (see the systemd section in the full tutorial for more information). Like the ps command, the top command is used to list processes currently running on your system.

Screen -t socket-local 0 forever /home/pi/socket-local/server.js While it is intended to start programs in the background, independent of any user-level desktop environments, you can still create unit files for systemd that wait until networking, graphics, etc. I can open 2 tabs, give them a name and start the processes like so: # /home/pi/startup Say I were to have two long running socket server scripts that I wanted to run separately. BONUS: How do we make this even more tasty?

Google for instructions on how to use screen, or check this quick reference I found when I did myself. The true niceness happens when you ssh into your Raspberry Pi ssh get to look at the script running! screen -DR Reboot for effect sudo reboot Yay, it runs the script on startup! What now? This is useful for system startup scripts.

This creates a new session but doesn't attach to it. We make use of two very convenient flags. Su - pi -c "screen -dm -S pistartup ~/startup" We show you five ways to start a program at Raspberry Pi boot.
#RASPBIAN SEE PROGRAMS RUNNING ON STARTUP INSTALL#
Install screen sudo apt-get install screenĮdit the root startup script file sudo nano /etc/rc.localĪnd the following line before exit 0 # Run a command as `pi` from the home folder In this tutorial we show you five ways you can run a program on your Raspberry Pi at startup. Make sure it's executable chmod +x ~/startup Configure the startup script It could look something like this #!/usr/bin/bash For this example, we'll use a script /home/pi/startup. Raspberry Pi systems, and Linux in general, give you a variety of ways to automate running programs.This document explains how to run a script every time you startup your Raspberry Pi and how to get access to the screen running it. If your rc.local script gets stuck, your boot sequence will not proceed, so be cautious about how you implement this functionality. The ampersand here allows other processes to execute while the program is executing. As seen below, I've entered python3 /home/blink3.py &. To edit, enter sudo nano /etc/rc.local into the terminal, then insert the program you want to run before the exit 0 text. Note that rc.local isn't dependent upon you logging in. Similar in function to bashrc, you can add functions to rc.local to have them run on bootup. You can even add echo commands to confirm that the routine is run on your terminal, as shown in the above images. Test your script out by entering source ~/.bashrc to run the file.

Note that this script won't run until you log in, which means you must enter your password and username on SSH or via the terminal however, it will automatically occur if booting into the desktop environment. Restart your Pi with sudo reboot now then log in to see the results. There's no need for anything else just hit ctrl+x to exit, and y then enter to save the file. On a new line at the bottom of the file, simply add your commands, such as python3 /home/blink3.py. You'll be taken to a text editor containing a variety of commands. To try it out, type in sudo nano /home/pi/.bashrc. While not as versatile as crontab, bashrc has a unique feature - it runs on boot and every time a new terminal is opened or you log on via SSH.

The python3 /home/blink3.py command will run a slightly modified blink3.py program (which blinks three times so you can tell which routine is running) each time it reboots. Additionally, cron can run a program every time on boot by using instead of numbers or stars for the time. * * * * * will run a command every minute, which in my case is the test program: python3 /home/blink.py. To test your setup, add lines as shown to the bottom of the text file. Enter the program below and hit ctrl+x to exit and save. This is accomplished by navigating to the home directory ( cd /home if needed) then typing sudo nano blink.py. I've written test programs similar to the blink.py routine below, which blinks the LED twice. Let's assume you're working from the command line, or logging into your Pi via SSH.įor this setup, install an LED on BCM pin 14 (aka physical pin 8 for testing) directly or via a transistor. Let's look at three methods to set up your programs to run automatically via the command line or SSH (Secure Shell). The crontab method is especially useful, as it not only starts a program upon bootup, but it can also run things at a set interval after bootup. Three ways to start a program on boot are explained here, with slightly different uses.
