[SOLVED] Display Items, but select original

anon033 · 06-26-2019, 10:45 PM

The title is terrible, but essentially sums up what I need to do. I have a script that does the following:

Code:

cds into the home directory

finds all the videos in the vids directory

sorts them into order

removes the pathway and makes them more orderly

pipes them into dmenu for selection

passes the selected item to mpv

the UNIX shell script used is as follows:

Code:

cd ${HOME} && find vids/ -type f \( -name "*.mp4" -o -name "*.mkv" \) | sort | sed 's/.*\///' | pmenu -l 5 | xargs -I {} mpv "{}"

Now this works, sorta. This does display the output how I want, but once I select a video and it gets passed to mpv it can't play the video as the video doesn't exist. This is due to the fact that when the sed command gets run it changes the name of the file that mpv will try to play. I really want to change the name shown as it looks so much better and makes it easier to read, but how do I get mpv to play the original video?

Some sample output would be this:

Code:

#This is the vinilla output without using sed to parse output:

The fix:

cd ${HOME} && find vids -name "*$chosen" -exec mpv \{} \;

You can't do it like that with either pmenu or dmenu I think - they simply spit back out what you chose.
This would require some proper scripting, possibly with bash arrays, not a oneliner.
Have you tried simply using bash's tab completion feature on the command line?

Code:

mpv vids<Tab><Tab>etc.

Or a command line filemanager like nnn?

wadapad · 06-27-2019, 06:55 AM

between pmenu and xargs, add another find with '-name $(cat)', so find will give xargs file with full path
or replace last xargs with 'find vids -name "$(cat)" -exec mpv "{}" \;'

I am very sorry, but could you give me a more detialed example? I am still learning the ins and outs of UNIX shell script and feel a little confused. To help myself with this I am breaking up the script like so

Code:

#!/bin/sh
cd ${HOME}

# find all videos
files=$(find vids/ -type f \( -name "*.mp4" -o -name "*.mkv" \))

# make titles easier to read
sorted=$("$files" | sort | sed 's/.*\///')

# select video to watch
chosen=$("$sorted" | pmenu -l 5 | xargs -I {} mpv "{}")

if I understand you correctly I am supposed to run:

Code:

find vids/ -type f \( -name "*.mp4" -o -name "*.mkv" \)

between

Code:

pmenu -l 5 |

# and 

xargs -I {} mpv "{}"

If you don't mind using a fuzzy-finder like fzy or fzf, you could probably do that in a couple of lines.

Code:

#!/bin/sh

listings="$(find vids -type f -print)"

mpv "$(echo -n "$listings" | fzy -q "$(echo -n "$listings" | sed 's|.*/||' | fzy)")"

Thank you, I'll keep this in my backpocket; but I want to do my best to do this with the tools I have at the moment.

Is it because you want to learn how "core utilities" work? Or is it because of "bloat?" There is a difference. Anyway, here is a POSIX-compliant version of the above, without the easy selection.

Code:

#!/bin/sh

cd "$HOME" || exit

find vids -type f -print | sed 's|.*/||'
read -p '> ' -r chosen
find vids -name "*$chosen" -exec mpv \{} \;

Thank you so much! This worked!

Code:

#!/bin/sh
chosen=$(cd ${HOME} && find vids/ -type f \( -name "*.mp4" -o -name "*.mkv" \) | sort | sed 's|.*/||' | pmenu -l 5)

cd ${HOME} && find vids -name "*$chosen" -exec mpv \{} \;

You're welcome. You can also do "*$chosen*" so you don't need to type the full name. I forgot to include that in my post.

Example:

Code:

Blade Runner 2049.mp4
Blade Runner.mp4
S01EP36 1.28.mkv
S01EP37 New World.mkv
S01EP35 Malice.mkv
> 1.28
Playing: vids/TV/Death Note/S01EP36 1.28.mkv

EDIT: Don't duplicate the work by cd'ing into $HOME twice. Just do it once at the beginning of your script.

IDK, I find this very... inelegant. and error perone, too: what if 2 videos are in different folders, but have the same name? And mpv does not seem to take a list of files by default.

Not that I could think of a better solution; the whole premise is faulty IMO.

Normally I would agree, but that wasn't the purpose of my post. It provided a starting point for the OP, and if he wants to expand, then more power to him. The directory/file structure is quite specific in this case so the likelihood of duplicate show/movie titles is low.

anon033 · 06-27-2019, 02:12 PM

I actually have one other thing I am trying to figure out if you have a moment, this is something I will actually be implementing in several scripts. As you know this script will find all videos in the vids directory. The way I order my directories is:

Code:

vids/TV/"show names"/"seasons if any is available"
vids/Movies/"name of movies"

Now the thing I want to add is that I want the output (IE when I select my video) to show sections, like show all tv shows under "TV/show name/season if any is there" and movies as "Movies/moviename". A better way to display this would be with an example, so a better visual would be this:

Code:

TV:

Death Note:

Season one:

S01EP01 Rebirth.mkv

ETC

Movies:

Blade Runner 2049.mp4
Blade Runner.mp4
ETC

I have no idea how to do this, what would be the best way to do this? I want to get this working here as I plan to use it in a similar script for music. Just for clarification this would mean that the show for example is stored under ~/vids/Death Note/Season One/EP Name

ondoho · 06-28-2019, 01:59 AM

So basically you want to split paths along '/' characters?
bash has some nice tools for that, specifically string manipulation:
https://mywiki.wooledge.org/BashFAQ/100 (you really want to read ALL of the BashFAQ)
Example:

Code:

#!/bin/bash

path="/home/ondoho/video/CSI Crime Scene Investigation/CSI - 3x23 - Inside The Box.avi"
lastbit="${path##*/}"
echo "$lastbit"
beforelast="${path%/$lastbit}"
beforelast="${beforelast##*/}"
echo "$beforelast"
# etc...

I'm not sure I completely understood your question. You want to print out all files that are in the same directory as the selected one? If that's what you want you can add a few lines to what you already have.

Code:

# list all files in the vids directory and allow a user to choose one.
mediaFile="$(find vids -type f -print | sed 's|.*/||' | sort | pmenu -l 5)"

# find the directory that the chosen file resides in.
mediaDir="$(find vids -iname "*$mediaFile*" -exec dirname \{} \; -quit)"

# remove vids/ from the front of the directory name; replace / with a newline; replace the end of each resulting string with ':.'
echo "$mediaDir" | cut -d'/' -f2- | tr '/' '\n' | sed 's|$|:|'

# list the contents of the directory.
ls -1 "$mediaDir"

# start mpv with $mediaFile here?

And the result:

Code:

TV:
Death Note:
Season One:
S01EP01 Rebirth.mkv
S01EP02 Confrontation.mkv

EDIT: I learned something new as well. You can stop find after the first match by using -quit.

anon033 · 06-28-2019, 11:43 AM

I am gonna rewrite this to make it easier to read (sorry about the last one, it was poorly formatted). What I am trying to do in this script is the following:

Code:

1) Find all videos in ~/vids/ (this is done using: find ${HOME}/vids/ -type f \( -name "*.mp4" -o -name "*.mkv" \))

2) Find the directories the files are listed in under ~/vids/ (IE: TV/showname/season or Movies/Moviename etc) I don't know how to do this part

3) Ask the user which video they want to watch via dmenu (which would look like this):

TV:

Death Note:

Season one:

S01EP01 Rebirth.mkv

ETC

Movies:

Blade Runner 2049.mp4
Blade Runner.mp4
ETC

4) Play the video the user selected

5) If the user doesn't select a video (IE $file = nothingor they use escape which closes dmenu) exit

Right now I have this version:

Code:

#!/bin/sh
chosen=$(find ${HOME}/vids/ -type f \( -name "*.mp4" -o -name "*.mkv" \) | sort | sed 's|.*/||' | pmenu -l 5)

find ${HOME}/vids/ -name "*$chosen" -exec mpv \{} \;

As you know this version asks the user which video to watch and then plays it. I can't figure out how I would get this to work the other way.
