How to use the command 'sl' (with examples)
This article provides examples of different use cases for the ‘sl’ command, which is used to display a steam locomotive running through the terminal. The ‘sl’ command is a fun and interactive way to add a little entertainment to your command line experience.
Use case 1: Let a steam locomotive run through your terminal
Code:
sl
Motivation:
This use case is the simplest and most basic use of the ‘sl’ command. It allows you to see a steam locomotive running through your terminal, adding a bit of visual interest to an otherwise static command line interface.
Explanation:
The ‘sl’ command without any arguments is used to start the steam locomotive animation in your terminal.
Example output:
(sl animation runs through the terminal)
Use case 2: The train burns, people scream
Code:
sl -a
Motivation:
This use case adds some additional animation and sound effects to the steam locomotive. It makes the train appear as if it is burning and includes a sound effect of people screaming. This can be a fun way to add a bit of excitement to your command line experience.
Explanation:
The ‘-a’ argument is used to enable additional animation and sound effects for the steam locomotive. It changes the appearance of the train to make it look like it is burning and includes a sound effect of people screaming.
Example output:
(sl animation with burning train and screaming sound effect)
Use case 3: Let the train fly
Code:
sl -F
Motivation:
This use case allows the steam locomotive to appear as if it is flying. It adds a whimsical and fantastical element to the command line experience, making it more visually interesting and enjoyable.
Explanation:
The ‘-F’ argument is used to enable the flying animation for the steam locomotive. It changes the appearance of the train to make it look like it is flying instead of running on tracks.
Example output:
(sl animation with flying train)
Use case 4: Make the train little
Code:
sl -l
Motivation:
This use case allows you to adjust the size of the steam locomotive. It can be useful if you want a smaller and less obtrusive animation in your terminal.
Explanation:
The ‘-l’ argument is used to make the steam locomotive appear smaller in size. It reduces the size of the animation, making it less prominent in the terminal.
Example output:
(smaller sl animation)
Use case 5: Let the user exit (CTRL + C)
Code:
sl -e
Motivation:
This use case provides a way for the user to exit the ‘sl’ animation. It can be used to stop the animation if you no longer want it to run in the terminal.
Explanation:
The ‘-e’ argument is used to enable the user to exit the ‘sl’ animation by pressing CTRL + C. When this argument is included, the animation will continue running until the user manually stops it.
Example output: (The animation continues until CTRL + C is pressed)
(sl animation runs until interrupted by the user)
Conclusion:
The ‘sl’ command is a fun and interactive way to add visual interest and entertainment to the command line. With different arguments, such as -a, -F, -l, and -e, you can customize the appearance and behavior of the steam locomotive animation. Whether you want a simple animation or a more elaborate and immersive experience, the ‘sl’ command provides a playful element to your command line interactions.
