Starting on a Raspberry Pi is not always easy because you don\u2019t necessarily have the habit of using command lines
\nHowever, they are essentials and often faster or more efficient than going through the GUI<\/p>\n
What are the vital commands to know? This list is based on my experience on Raspberry and Linux in general These commands are the basics that every Linux beginner should learn You can specify the number of lines to display with -n<\/p>\n And finally, my favorite is the option -f to displays new lines in real-time<\/p>\n As I say, you can use it on a file or a script output:<\/p>\n And finally, there is a lot of options to use with grep, like regular expressions or options to display lines before (-B), after (-A) or around (-C) the search string If you like this tool, I recommend you to read the man page to know exactly what you can do with<\/p>\n You\u2019ll find all actions available at the bottom of the screen<\/li>\n -c: create an archive -x: extract an archive<\/li>\n There is a lot of options to help you find the good file (size, last modification date, \u2026)<\/li>\n Shortly after your first Raspbian installation, you\u2019ll surely need some of this commands to help you with the network configuration (especially if you are on a lite version or with SSH)<\/p>\n
\nWell, there are quite a few, and here we will see the 50 most used sorted by category:<\/strong><\/p>\n\n
\nEveryone has a different use of his system and can use more often commands that are not present here
\nThe goal is really to introduce the essential commands to start, and not to make an exhaustive list<\/p>\nFiles management<\/h2>\n
\nMaybe you already know them, but it will be a reminder<\/p>\nThe Linux arborescence is a Tree, starting at the root: \/\nEach subfolder created under is accessible with \/\nEx: \/home\/pi => pi is a subfolder of \/home, home is a subfolder in \/\nDon't forget to use sudo if you are not allowed to access the file or directory (sudo gives you administrator privileges for the command that follows)<\/pre>\n

\nBasic usage:<\/p>\n
\nYou can also use -v to display everything except the input string<\/p>\n
\nBut quickly, it allows you to edit a file, and save your changes with (CTRL + O, Enter, CTRL + X)<\/p>\n
\n-v: verbose
\n-f: filename of the archive follow
\n-z: compress files with gzip<\/li>\npi@raspberrypi:\/var\/log $ tree\n.\n|-- alternatives.log\n|-- alternatives.log.1\n|-- alternatives.log.2.gz\n|-- apt\n| |-- eipp.log.xz\n| |-- history.log\n| |-- history.log.1.gz\n| |-- history.log.2.gz\n| |-- term.log\n| |-- term.log.1.gz\n| `-- term.log.2.gz\n...<\/pre>\n<\/li>\n<\/ul>\n
<\/span>Network commands<\/h2>\n
<\/span>Configuration<\/h3>\n
By default, the Raspberry Pi 3B+ comes with 2 interfaces (Ethernet and WiFi)\nThe ethernet is called eth0 and the WiFi is wlan0\nYou have to use these names with some of the commands below<\/pre>\n
