So I've been messing around with the webp encoder cli tool and I really wish I could quickly achieve a workflow more similar to photoshop's previews. Is there a GUI tool out there where I can specify the arguments for an CLI executable then it lets me adjust the values and run the command. Ideally it would automatically let me view the output file, and define presets would be great.

I use this constantly, it just plays music by file name, specifically matching *NAME* with case-insensitivity. Requires bash 4.something.

# play -ln SONGS ...
# -l don't shuffle
# -n dry run
mpv_args="--no-audio-display --no-resume-playback \
          --msg-level=all=status --term-osd-bar"
shopt -s globstar nullglob nocaseglob

shuffle=true
dry=false
while [[ "$1" == -* ]]; do
    if [[ "$1" == "-l" ]]; then 
        shuffle=false
    elif [[ "$1" == "-n" ]]; then
        dry=true
    fi

    shift 1
done

if [[ "$shuffle" == true ]]; then
    mpv_args="--shuffle $mpv_args"
fi

songs=()
while [[ "$#" != 0 ]]; do
    songs+=( ~/music/**/**/*"$1"*.* ) # change this to match your music directory layout
    shift 1                                               # could probably use find instead
done

if [[ "$dry" == true ]]; then
    if [[ "$shuffle" == true ]]; then
        printf "Shuffle mode is on\n"
    fi

    for song in "${songs[@]}"; do
        printf "$song\n"
    done
  
    exit
fi

if [[ ${#songs[@]} != 0 ]]; then
    mpv $mpv_args "${songs[@]}"
fi

I make no claims to the quality of this but it works!
