Filing and directory manipulation

Managing files and directories is a fundamental skill when working in a Unix-based environment. As a data scientist, you’ll frequently need to create, delete, move, and copy files and directories. Knowing how to use these commands in your daily activities may become a core skill, depending on the systems you are using. However, in a technical interview, these topics might occasionally come up. Therefore, we will only quickly review a few core operations here.

The following list will explain these operations and discuss how to manipulate file and directory contents:

• Creating files: To create a new file, use the touch command followed by the name of the file you want to create. For instance, to create a file named analysis.py, you would use the following command:

  touch analysis.py

• Creating directories: To create a new directory, use the mkdir command. For example, to create a directory named new_data, use the following:

  mkdir new_data...
