# Command line interface
|
|
|
|
The Raspberry Pi OS, Raspbian, uses CLI as its primary user interface (which is common for Linux-based operating systems). You can use [a secure shell connection](ssh.md) to access the command line.
|
|
|
|
## Basic commands
|
|
|
|
> **Hint** Double-tapping the `Tab ↹` key autocompletes the command or its argument. This is known as "tab completion".
|
|
|
|
Show the contents of the current directory:
|
|
|
|
```bash
|
|
ls
|
|
```
|
|
|
|
Change current (working) directory:
|
|
|
|
```bash
|
|
cd catkin_ws/src/clover/clover/launch
|
|
```
|
|
|
|
Go one directory level up:
|
|
|
|
```bash
|
|
cd ..
|
|
```
|
|
|
|
Print path to the current directory:
|
|
|
|
```bash
|
|
pwd
|
|
```
|
|
|
|
Go to the user's home directory:
|
|
|
|
```bash
|
|
# all three commands are equivalent, where the tilde character (~) is an abbreviated
|
|
# path entry to the home directory, and the $HOME variable stores this path
|
|
cd
|
|
cd ~
|
|
cd $HOME
|
|
```
|
|
|
|
Print contents of the `file.py` file:
|
|
|
|
```bash
|
|
cat file.py
|
|
```
|
|
|
|
Run `file.py` as a Python script:
|
|
|
|
```bash
|
|
python3 file.py
|
|
```
|
|
|
|
Reboot Raspberry Pi:
|
|
|
|
```bash
|
|
sudo reboot
|
|
```
|
|
|
|
You can terminate currently running (foreground) program by pressing `Ctrl`+`C`.
|
|
|
|

|
## Editing files {#editing}
|
|
|
|
You can use **nano** to edit files on the Raspberry Pi. It is one of the more user-friendly console-based text editor.
|
|
|
|
1. Use the following command to edit or create a file:
|
|
|
|
```bash
|
|
nano path/to/file
|
|
```
|
|
|
|
For example:
|
|
|
|
```bash
|
|
nano ~/catkin_ws/src/clover/clover/launch/clover.launch
|
|
```
|
|
|
|
<img src="../assets/nano.png" alt="Editing files in nano" data-action="zoom">
|
|
2. Edit the file.
|
|
3. Press `Ctrl`+`X`, `Y`, `Enter` to save your file and exit.
|
|
4. Restart the `clover` service if you've changed .launch files:
|
|
|
|
```bash
|
|
sudo systemctl restart clover
|
|
```
|
|
|
|
You may also use other editors like **vim** if you prefer.
|
|
|
|
## Resetting changes
|
|
|
|
For resetting all the changes in Clover package related files (`launch`-files), use git:
|
|
|
|
```bash
|
|
cd ~/catkin_ws/src/clover
|
|
git checkout .
|
|
sudo systemctl restart clover
|
|
```
