The Coder’s Computer Notes

What are four important features to look for in a text editor?

  1. code completion
  2. syntax highlighting
  3. a nice variety of themes (to reduce eye strain and fatigue)
  4. the ability to choose from a healthy selection of extensions available when you need them

What do the following commands do?

Basic commands used in the command line interface of a Unix-b ased operating system such as Linux or macOS.

  1. pwd: Stands for “print working directory.” It shows the current working directory, which is the directory in the file system where the user is currently located.

  2. ls: Stands for “list.” It shows the contents of the current directory, which can include files, directories, and other types of files.

  3. cd: Stands for “change directory.” It is used to navigate through the file system and change the current working directory to a new location.

  4. mkdir: Stands for “make directory.” It creates a new directory (folder) in the file system with the specified name.

  5. touch: Used to create a new file in the file system with the specified name. If the file already exists, it updates the timestamp of the file.

Can you explain what is happening in the following scenario if these commands and arguments are entered into the command line? (Arguments are extra instructions given to a command.)

  1. cd projects: Changes current directory to the “projects” directory.

  2. mkdir new-project: Creates a new directory named “new-project” inside the “projects” directory.

  3. touch new-project/newfile.md: Creates a new file named “newfile.md” inside the “new-project” directory.

  4. cd ..: Changes the current directory to the parent directory.

  5. ls projects/new-project: Lists the contents of the “new-project” directory inside the “projects” directory. Since we created a file called “newfile.md” inside that directory, if it is listed then we can confirm the new file was created successfully.
