Create files or directories with underlying path

Usage Examples:

tt foo/bar/file  # => Create a file with parent directories relative to the current path "/current/path/foo/bar/file"
tt /foo/bar/file # => Create a file with parent directories starting with an absolute path "/foo/bar/file"
tt /foo/bar/dir/ # => Append "/" to the path to create a directory with parent directories "/foo/bar/dir"

Install or update:

wget -O /tmp/tt -- https://gist.githubusercontent.com/zinovyev/1f8caf9e886de610e2dd2c22a4ef7d69/raw/tt ; \
chmod +x /tmp/tt ; \
sudo mv -f /tmp/tt /usr/bin/tt
