For some of my projects I write a simple service in Python and need it to start running in the background when the Raspberry Pi boots. Different Linux distributions use different ways of starting and stopping services (some now use Upstart, some systemd). I am using the “Wheezy” Debian distribution on my Raspberry Pi, and in this case the proper way to do this is using an “init script”. These are stored in the /etc/init.d folder. In there you can find scripts that for instance, start the networking system or a print server. Debian Wheezy uses the old Sys V init system which means that these scripts are run according to symbolic links in the /etc/rc.x directories. The Debian documentationexplains this.

Ubuntu MATE for the Raspberry Pi 2 and Raspberry Pi 3
Martin Wimpress and Rohith Madhavan have made an Ubuntu MATE image for the Raspberry Pi 2 and Raspberry Pi 3 which you can download or build yourself.
The image is based on the regular Ubuntu armhf base, not the new Snappy Core, which means that the installation procedure for applications is the same as that for the regular desktop version, ie using apt-get. However, since Ubuntu MATE 16.04 snap packages can be installed alongside classic deb packages. Continue reading Ubuntu MATE for the Raspberry Pi 2 and Raspberry Pi 3
find 命令
Linux中find常见用法示例
·find path -option [ -print ] [ -exec -ok command ] {} \;
find命令的参数；
pathname: find命令所查找的目录路径。例如用.来表示当前目录，用/来表示系统根目录。
-print： find命令将匹配的文件输出到标准输出。
-exec： find命令对匹配的文件执行该参数所给出的shell命令。相应命令的形式为’command’ { } \;，注意{ }和\；之间的空格。
-ok： 和-exec的作用相同，只不过以一种更为安全的模式来执行该参数所给出的shell命令，在执行每一个命令之前，都会给出提示，让用户来确定是否执行。 Continue reading find 命令
