ls

Ls used to display everything in some directory, by default ls doesn’t show hidden (started with .) files and directories.

ls is one of most popular GNU Utilities tool.

List of common commands:

• List files in directory: ls <dir>
• Display everything in <dir>, including hidden files: ls -a <dir>
• Display all files, along with the size and timestamp: ls -lh <dir>
• Display files, sorted by size: ls -S <dir>
• Display directories only: ls -d */ <dir>
• Display directories only, include hidden: ls -d .*/ */ <dir>
• Display files sorted by create time: ls -lt
• To display files in a single column, without details: ls -1
• Show all the subtree files (Recursive Mode): `ls -R

I also use “modern” replacement - eza, with dynamic aliases in my Zsh config (~/.zshrc file):

if (( $+commands[eza] )); then
  IGNORE_GLOB="UnrealEngine"
  alias eza="eza --group-directories-first --git";
  alias l="eza -bl -I $IGNORE_GLOB";
  alias ll="eza -abghilmu -I $IGNORE_GLOB";
  alias la="LC_COLLATE=C eza -ablF -I $IGNORE_GLOB";
  alias lm='ll --sort=modified'
  alias tree='eza --tree'
  alias treel='eza --color=always --tree|less'
else
  alias l='ls'
  alias ll='ls -la'          # long listing format
  alias la='ls -d .* --color=auto' # hidden files
  alias lm='ls -lt'          # by modification date, newest first
fi
