Command Line

Knowing the shortcuts to navigate between directories can save you a huge amount of time. The GIF above shows the two cd commands that I use the most.

If you want to grab multiple files then do something with them, try fd.
For example, you can -x to apply the rm command on the files that end with txt.
You can find more about fd in my latest article.

If you want to measure the execution time of small code snippets on your terminal, use python -m timeit. Find an example of timeit in the image above.

Have you ever wanted to quickly try some ideas popping up in your head using a Python Shell (REPL)? You might be hesitant to use a classic Python shell since it doesn’t support auto-completion or docstring as Jupyter Notebook does.
You also cannot fix the mistake in the code after hitting Enter.
What if you can turn your boring Python shell into a multi-functional shell like above?
That is when ptpython comes in handy.

Have you ever wanted your terminal to display colorful text and symbols when executing “ls”? If so, try colorls.
After installation, the output of your “ls” command will look like above.

If you want to change the name of the command because it is too long to type or too complicated to remember, try symbolic link.
Symbolic link is a special type of file that points to another file or directory. In the code above, I can execute htop when typing information because they are linked.
Note: Use which <new_file_name>to make sure that <new_file_name> doesn’t already exist in your directory.
 

Is there a way that you can quickly search for files or directories that contains a specific pattern without dealing with complicated syntax?
That is when fd comes in handy. fd allows you to search for files or directories by typing fd pattern instead of typing find -iname '*pattern*.
Find other things that fd can do above.
Note that you can use fd for Linux, Mac OS, and Windows.
