raspberry pi terminal commands

Reference: RPi Serial ConnectionThis article from: Http://www.raspberry-projects.com/pi/programming-in-c/uart-serial-port/using-the-uartUsing the UARTIf you is running Raspbian or similar then the UART would be used as a serial console. Using a suitable cable, such as the Ttl-232r-3v3-we, you can connect it to your PC and using some simple terminal software Set to 115200-8-n-1 use the command line interface

activated the next time you start Raspberry Pi. There are also. Bash_aliasesFile Reference. By default, this file does not exist: if [ -f ~/.bash_aliases ]; then . ~/.bash_aliasesfi The IF condition is used to check whether the file exists between the imported files. You can create this. Bash_aliasesFile, and add more aliases in it, for example: alias gs='git status' You can also directly add other th

Raspberry Pi's. bashrc and. bash_aliases files, In your home directory, you can find a hidden file that contains user configurations.. Bashrc. You can modify the file as needed. The file provides some useful adjustment settings. By default, some of these settings are commented out. For example, someLsCommand alias: alias ls='ls --color=auto'#alias dir='dir --color=auto'#alias vdir='vdir --color=auto'alias grep='grep --color=auto'alias fgrep='fgrep --c

Raspberry Pi 2 install the latest version FPC and Lazarus 1.5 The Raspberry Pi2 launched in February 2015 does not support Lazarus installation using the previous method. When installing fpc, the following problems occur. Slave:1. Install subversion and unzipSudo Apt-get updateSudo Apt-get install subversion unizp2. Obtain and compile the latest FreePascal Compil

Because the Raspberry Pi is an arm architecture, there is no binary package download for ARM architecture on node. js. Tried using apt package to manage installation and direct node. JS source code compilation installation (compiled for four or five hours ...) ), failed to report an illegal instruction error, or due to a compiled processor architecture error. However, some of Google's small partners have su

Raspberry Pi-Cron, Crontab (scheduled task), croncrontab Cron is a tool for configuring scheduled tasks in Unix systems. It is used to execute commands or scripts on a regular basis or at a certain interval; the task scope can be to automatically back up the user's home folder every night, or to record CPU information logs every hour. The crontab (cron table) com

Linux-Raspberry Pi system partition There are two main partition commands: fdisk and parted.Both commands require the root permission,First, we will introduce the fdisk command: Fdisk allows you to view the usage of the current file system. fdisk -l Because I installed the system on the SD card, the partition starts

to open another file, enter something and then pause the session. If you enter "FG" you will go back to the second file opened with Nano. You will only be back to the first file opened with Nano until you exit the Nano and enter "FG".4. Use Nohup to still run commands after logging out of an SSH sessionThe nohup command is really useful if you are using SSH to log on to other machines.So how do you use Nohup?Imagine that you telnet to another compute

I've been using Linux for 10 years, and I'm going to show you a series of commands, tools, and techniques from the beginning, and I hope someone tells me that from the start, not the way I've been growing. 1. command line daily system shortcuts The shortcuts below are very useful and can greatly improve your productivity: CTRL + U-cut content before the cursor CTRL + K-cut the cursor to the end of the line CTRL + Y-paste CTRL + E-Mov
