I use prefix qq for my commands because:

  1. It is easy to discover all customizations 
     via autocomplete
  2. It is not going to clash 
     with existing functionality

  # (Sort stuff by size, latest down, in a directory)
  alias qqsize="ls -lSrh"
  alias qqdate="ls -lrt"
  
  # First 100 of largest files/directories in a folder

    du -a ./ | sort -n -r | head -n 100
  }

  # Symlink config file
  # 1. Move dotfile to a config directory.
  # 2. Strip the dot

  function qqsymlink_config_file(){
      directory_for_dot_file=$2
      name_of_dot_file=$1
      basename_of_dotfile=$(basename $name_of_dot_file)
      echo "Basename of dotfile: $basename_of_dotfile"
      dot_file_with_striped_dot=${basename_of_dotfile:1}

     while true; do 
      echo -ne "$(date -u --date @$((`date +%s` - $date1)) +%H:%M:%S)\r"; 
      sleep 0.1
     done

Some other stuff that I use daily and is too long to list here is:

  * an increment, deduplicating backup that takes
    around $0.52 per month on BackBlaze and on the 
    external hard drive via one command. 
    (Shameless plug: https://github.com/MichaelLeachim/borg_backblaze_backup)
  * Internet blocker.  (https://github.com/MichaelLeachim/internet_block)

Edit, formatting.
