Tutorial: How to run a program from boot<\/p>\n
Having a program start by itself when you boot your Raspberry Pi can be very useful. There are a few ways of running a command at start-up, but in this tutorial we will create a script within etc\/init.d so that when the system boots the program will start\/stop automatically on boot\/shut-down. <\/p>\n
For the purpose of this tutorial we will show you the method for an arbitrary program created in python ‘example.py’ with its location \/home\/pi\/example.py. The following code will work for any script, just replace ‘example’ with name of your program and replace \/home\/pi\/example.py to wherever you are actually keeping your script.<\/p>\n
First we need to create a script within \/etc\/init.d\/. Type the following command in the terminal but replace ‘example’ with the name of your own program:<\/p>\n
sudo nano \/etc\/init.d\/example<\/p>\n
This will open a text editor. Paste the following code into here and replace the name and location of the program with your own. The the examples are the ones you’ll need to change:<\/p>\n

Now you can reboot your Raspberry Pi and the program ‘example’ should start up automatically.<\/p>\n If you ever wish to stop the program running from boot type the following command:<\/p>\n sudo update-rc.d -f example remove<\/p>\n","protected":false},"excerpt":{"rendered":" Tutorial: How to run a program from boot Having a program start by itself when you boot your Raspberry Pi can be […]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-2519","post","type-post","status-publish","format-standard","hentry","category-info-on-tech"],"_links":{"self":[{"href":"https:\/\/blog.designed79.co.uk\/index.php?rest_route=\/wp\/v2\/posts\/2519","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blog.designed79.co.uk\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blog.designed79.co.uk\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blog.designed79.co.uk\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/blog.designed79.co.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=2519"}],"version-history":[{"count":0,"href":"https:\/\/blog.designed79.co.uk\/index.php?rest_route=\/wp\/v2\/posts\/2519\/revisions"}],"wp:attachment":[{"href":"https:\/\/blog.designed79.co.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=2519"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blog.designed79.co.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=2519"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blog.designed79.co.uk\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=2519"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}} |
