FILE AND DIRECTORY COMMANDS
- cat example.txt: Displays the contents of the file example.txt.
- cd /abc/xyz: Changes the current directory to the /abc/xyz directory.
- cp XXX: Copies the file or directory XXX and pastes it to a specified location; i.e. cp examplefile.txt /home/pi/office/ copies examplefile.txt in the current directory and pastes it into the /home/pi/ directory. If the file is not in the current directory, add the path of the file’s location (i.e. cp /home/pi/documents/examplefile.txt /home/pi/office/ copies the file from the documents directory to the office directory).
- ls -l: Lists files in the current directory, along with file size, date modified, and permissions.
- mkdir example_directory: Creates a new directory named example_directory inside the current directory.
- mv XXX: Moves the file or directory named XXX to a specified location. For example, mv examplefile.txt /home/pi/office/ moves examplefile.txt in the current directory to the /home/pi/office directory. If the file is not in the current directory, add the path of the file’s location (i.e. cp /home/pi/documents/examplefile.txt /home/pi/office/ moves the file from the documents directory to the office directory). This command can also be used to rename files (but only within the same directory). For example, mv examplefile.txt newfile.txt renames examplefile.txt to newfile.txt, and keeps it in the same directory.
- rm example.txt: Deletes the file example.txt.
- rmdir example_directory: Deletes the directory example_directory (only if it is empty).
- scp user@10.0.0.32:/some/path/file.txt: Copies a file over SSH. Can be used to download a file from a PC to the Raspberry Pi. user@10.0.0.32 is the username and local IP address of the PC, and /some/path/file.txt is the path and file name of the file on the PC.
- touch example.txt: Creates a new, empty file named example.txt in the current directory.
