It uses the privilege only to scan `/dev/input/*` folder and open the selected input device. After that it lowers its privilege down to its real uid/gid and continues to function like a regular user application.\n\n### setuid example\n\n```\n# cp voidf /usr/local/bin\n# chown root:root /usr/local/bin/voidf\n# chmod 4755 /usr/local/bin/voidf\n```\n\n### setgid example on Debian\n\nOn my Debian Stale 10 I have a group called `input` that has the access to `/dev/input/*` files. So this is what I do on my machine:\n\n```\n# cp voidf /usr/local/bin\n# chown root:input /usr/local/bin/voidf\n# chmod g+s /usr/local/bin/voidf\n```\n\nThis way voidf is never ran with root privileges. It is only ran with temporary `input` group privilege just to open the input device file.\n\n## Controls\n\nTo increment the counter you have to type the sequence of characters `voidf`. Focus on the main window is not required.\n\nThe following actions do require the window focus tho:\n\n| Shortcut | Description |\n| --- | --- |\n| \u003ckbd\u003eF5\u003c/kbd\u003e | Reset the counter |\n| \u003ckbd\u003eCtrl + Z\u003c/kbd\u003e | Undo the counter reset |\n\n## References\n\n- https://github.com/freedesktop-unofficial-mirror/evtest/blob/b8343ec1124da18bdabcc04809a8731b9e39295d/evtest.c\n- https://www.gnu.org/software/libc/manual/html_node/Setuid-Program-Example.html\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftsoding%2Fvoidf","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftsoding%2Fvoidf","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftsoding%2Fvoidf/lists"}
