# Usage:        ff [option] [path file or folder]
#
#               --help : prints usage info
#               -v     : prints created files
#
# Description:  Bash script which is a combination of 'mkdir' and 'touch'.
#               It can create directory structures and files simultaneously
#               and lists the created objects using eza, lsd, or ls.
#
# Dependencies: bash
#               eza (optional)
#               lsd (optional)
#
# Examples:     - Single file:
#                   ff file
#               - Single directory:
#                   ff dir/
#               - Multiple files:
#                   ff file1 file2 file3
#               - Multiple directories:
#                   ff dir1/ dir2/ dir3/
#               - File in a directory
#                   ff dir/file
#               - Directory in a directory
#                   ff dir1/dir2/
#               - Multiple files in multiple directories
#                   ff dir1/dir2/file1 dir3/file2
#               - If your shell supprts brace expansion e.g bash, zsh, fish
#                   ff dir1/{dir2/{file1,file2}.txt,dir3/file3.txt}
