my-ls

Objectives

• my-ls consists on creating your own ls command.

• The ls command shows you the files and folders of the directory specified after the command. By exclusion of this directory, it shows the files and folders of the present directory.

• The behavior of your ls must be identical to the original ls command with the following variations :

  • You must incorporate in your project at least the following flags of the ls command :
    • -l
    • -R
    • -a
    • -r
    • -t
  • Note that you can use various flags, in various ways, just like in ls.
  • When it comes to the ls -l display, it must be identical to the system command.
  • Other flags displays are up to you.

Instructions

• Your project must be written in Go.
• The code must respect the good practices.
• It is recommended to have test files for unit testing.
• The use of the os/exec package is prohibited within the my-ls codebase.

Allowed packages

• fmt
• os
• os/user
• strconv
• strings
• syscall
• time
• math/rand
• errors
• io/fs

Hint

• We strongly recommend that you account for the implications of the option -R from the very beginning of your code.

• The order that files and folders appear must be taken in consideration.

• We suggest that you consult the ls command manual.
