    this isn’t perfect but i made one when i wanted to fetch a video for a specific resolution (because i prefer 480)

    ytgrab() {  
      local id="$1"  
      local res="${2:-480}" # default to 480  
      local url="https://www.youtube.com/watch?v=$id"  
    
      # fetch formats  
      local fmt  
      fmt=$(yt-dlp -F --cookies-from-browser vivaldi "$url")  
    
      # printing the format output  
      echo "$fmt"  
    
      # pick video format matching the requested resolution  
      local vfmt  
      vfmt=$(echo "$fmt" | awk -v r="${res}p" '$0 ~ r && /video/ {print $1}' | head -n1)  
    
      # pick best m4a audio  
      local afmt  
      afmt=$(echo "$fmt" | awk '/m4a/ && /audio/ {print $1}' | head -n1)  
    
      # safety check  
      if [ -z "$vfmt" ] || [ -z "$afmt" ]; then  
        echo "Could not find matching formats (video ${res}p or m4a audio)."  
        return 1  
      fi  
    
      echo fetching: yt-dlp -f ${vfmt}+${afmt} --cookies-from-browser vivaldi --write-subs --no-write-auto-subs --sub-lang "en.*" $url  
      yt-dlp -f "${vfmt}+${afmt}" --write-subs --cookies-from-browser vivaldi --no-write-auto-subs --sub-lang "en.*" "$url"  
    }

    You could make it an alias and shorten the number of keystrokes

    I prefer keeping my aliases in ~/.bash_aliases, which is sourced in my ~/.bashrc, ie

    . ~/.bash_aliases
    

    Then you would just need to source your bashrc to load it the first time.

    Very happy you had fun making the little script! One thing that will become important pretty quick if you continue making these scripts is that it’s almost always better to wrap your variables in quotes - so it becomes yt-dlp -x “$a. It’s okay here but if you ever paste something that has a space in it, this will keep it together ‘as one’.

    If you want to expand your knowledge with this, some fruitful paths to go down are the following:

    • can you find a way to download multiple urls one after the other if you paste them all at once? (Multiple arguments)
    • can you find a way to ask the user for these multiple urls one after the other? (loops)
    • and can you find a way to have it ask until you hit enter without a url pasted and only then it starts? (conditionals and test)

    The last one is already quite a bit advanced but if you can do that you have enough of the ‘programming’ basics of the shell down to a degree that you can create many little helpers like this with ease.

    Of course don’t feel forced to do any of that - if you’re happy with the improvement as-is, that’s all you need to enjoy the fun of Linux!

      Thanks might make it bigger now. The “$a” very helpful as I might copy url from web pages which may cause a error.

      Oh man, this reminds me of the joke that any program that’s more complex than Hello World has bugs – and folks still don’t even agree how to spell “Hello, World!”.

      Of course, Bash is a particular minefield in this regard…

        I once wrote a 2 line, 10 word script that had 9 bugs in it. I’m not overly proud of that one.

    Amazing.

    Injust switched a year ago and now I finally discovered bash scripts.

    It is so mich easier, I also automated some manual tasks with Python scripts to name my PDFs, never would have done that with windows.

    And the best part of it, it’s actually fun and I want to even do more.

    As always I have to thank DJT, for make me switch. 🤣

    Guess we’re sharing scripts now. I have a script that downloads playlists as MP3s and keep an archive.

    #!/usr/bin/env sh
    
    browser_cookies="firefox:1cvnyph7.YouTube TV"
    
    download() {
    	url="https://www.youtube.com/playlist?list=%241"
    	dir=$2
    	archive_name=$3
    
    	yt-dlp -x --audio-format mp3 --embed-thumbnail --embed-metadata --cookies-from-browser "$browser_cookies" --download-archive "archives/$archive_name.txt" -P "$dir" -o "%(title)s.%(ext)s" "$url"
    }

    That’s great! Here’s a few tips to take it a bit further; the world is your oyster!

    Open your .bashrc file (e.g. /home/yourusername/.bashrc) and add the following:

    alias get="/path/to/your/bash/file"

    Now open a terminal and type get, and it’ll launch the script. No clicking needed, it’ll run anytime from any terminal!

    And if you do use the alias then you can use another refinement, you can drop the echo: instead of $a, you can use $1 and remove the echo & read as you no longer need them:

    #! /usr/bin/bash yt-dlp -x $1

    Now for example you can type in a terminal:

    get http://url.to.video/

    And yt-dlp will do it’s stuff. $1 passes the first parameter after starting the script as a variable to it.

    You can use the keyboard shortcut Control+shift+v to paste a URL into the terminal, no mouse needed; just remember to add a space after typing get

      The op script is meant to be opened in the GUI in a terminal then the URL gets pasted in there. It took me a second to see it.

      What does your ~/.bashrc look like? My last change was modifying a playlist command

      spoiler: I explain my last change to my ~/.bashrc file
      playlist https://www.youtube.com/@YouTube/videos
      

      or

      playlist /home/username/Videos
      

      or just from any directory with files

      playlist
      

      And then takes all the videos found at the url or at the path (including within folders), adds them to a playlist, shuffles them, and plays them from mpv.

      playlist() {
              param=""
      
              # If the first parameter has a length more than 1 character
              if [ ${#1} -gt 1 ]; then
                      param="${@}"
              else
                      param="."
              fi
      
              screen mpv $param --shuffle --ytdl-raw-options-add=cookies-from-browser=firefox --loop-playlist=inf --no-keepaspect-window --no-auto-window-resize
      }
      
      other functions and aliases in my ~/.bashrc

          The version I have was copied from stackoverflow. It doesn’t work very well, it makes a rough estimate to get the video file size under the set value. As an example

          resize video.mp4 10
          

          Which then resizes the video to 10 megabytes if possible.

          resize.sh code
          file=$1
          target_size_mb=$2  # target size in MB
          target_size=$(( $target_size_mb * 1000 * 1000 * 8 )) # target size in bits
          length=`ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 "$file"`
          length_round_up=$(( ${length%.*} + 1 ))
          total_bitrate=$(( $target_size / $length_round_up ))
          audio_bitrate=$(( 128 * 1000 )) # 128k bit rate
          video_bitrate=$(( $total_bitrate - $audio_bitrate ))
          ffmpeg -i "$file" -b:v $video_bitrate -maxrate:v $video_bitrate -bufsize:v $(( $target_size / 20 )) -b:a $audio_bitrate "${file}-${target_size_mb}mb.mp4"
          

          I’ll probably replace it eventually.

            Definitely not the same lol

            Mine uses ffmpeg to change the resolution, it doesn’t so much care about file sizes.

            It could be a one-liner if you only ever feed it a single file to manipulate…

              I might add one for scaling. I just don’t use it as frequently as trying to meet a file size limit. The scaling is also much easier to remember

              ffmpeg -i  in.mp4 -vf "scale=600:-1" -an out.mp4
              

              It does get complicated though, when scaling many videos and images, I’ve used something like the following in the past

              find .  -exec ffmpeg -i {} -vf "scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:-1:-1:color=black" {}.mp4 \;
              

              Those were the only two that showed up when I typed history | grep scale.

              after commenting, I also added a new video file resizer.

              It works significantly better than the one I previously posted. It’s also copied from stackoverflow.

              bitrate="$(awk "BEGIN {print int($2 * 1024 * 1024 * 8 / $(ffprobe \
                  -v error \
                  -show_entries format=duration \
                  -of default=noprint_wrappers=1:nokey=1 \
                  "$1" \
              ) / 1000)}")k"
              ffmpeg \
                  -y \
                  -i "$1" \
                  -c:v libx264 \
                  -preset medium \
                  -b:v $bitrate \
                  -pass 1 \
                  -an \
                  -f mp4 \
                  /dev/null \
              && \
              ffmpeg \
                  -i "$1" \
                  -c:v libx264 \
                  -preset medium \
                  -b:v $bitrate \
                  -pass 2 \
                  -an \
                  "${1%.*}-$2mB.mp4"
