    In perl, using one of my favorite module: Path::Tiny.

    From the doc:

    Combines mkpath and touch. Creates the parent directory if it doesn't exist, before touching the file.

    I like typing very little, so I put this command into a named fn in my .profile, but I used this formulation for years before I did it:

    mkdir -p dirname/sub/dir && touch $_/filename.ext

    The variable $_ stores the last argument to the previous command. Pretty handy to know about overall.
