=============================================================================== ===============================================================================
shelltube will be a collection of (pretty POSIX) shell scripts to shelltube is a simples shell-script that lets you browse Youtube--
browse YouTube quickly, and entirely without captive UIs. searching for playlists, videos, channels, showing their metadata
Right now, there's only one script, yt-search (including items on playlsits and channels, etc) all from the terminal.
shelltube is written in pure shell; its only dependencies It YouTube quickly, and entirely without a captive UI.
are any modern shell (pdksh, bash, zsh), lynx, and curl/wget/ftp.
Your terminal should accept ANSI color-codes, too~
Before, shelltube was a set of scripts that culimated in a wrapper shelltube is written in pure shell; its only dependencies are any
script for browsing Youtube (like mpsyt). You could even download modern shell (pdksh, bash, zsh), lynx, and curl/wget/ftp.
videos from YT in pure shell! But, now, all videos require JS execution
to download (as far as I can tell), so it stopped working.
Now I'm refocusing a bit, ditching the wrapper script (begone, captive UIs, Your terminal should accept ANSI color-codes, and be >79chars wide,
ye spectre of ole!), and starting from scratch. :) for best experience~
shelltube isn't for downloading videos-- it's for *browsing* for them.
Use youtube-dl or something for that, that's not my job. :P
----------------------------------------
INSTALLATION
----------------------------------------
Just place "ytlib.sh" in either the CWD, ./lib/ytlib.sh, /usr/lib/, or
/usr/local/lib/
Then put `gendl` and `yt` in your $PATH. /usr/local/bin/ is nice (IMO),
or ~/bin/.
Profit!
----------------------------------------
EXAMPLES
----------------------------------------
yt video --search "wixoss op 1"
yt v -s "wixoss op 1"
yt playlist --search "my hero academia ops"
yt p -s "my hero academia ops"
yt playlist --title "PLY4D6ucZdLWC_yM3R_A1Hj9fAXZO_rSeK"
yt p -t "PLY4D6ucZdLWC_yM3R_A1Hj9fAXZO_rSeK"
yt playlist --list "PLY4D6ucZdLWC_yM3R_A1Hj9fAXZO_rSeK"
yt p -l "PLY4D6ucZdLWC_yM3R_A1Hj9fAXZO_rSeK"
yt video --author "https://youtube.com/watch?v=yu0HjPzFYnY"
yt v -a "https://youtube.com/watch?v=yu0HjPzFYnY"
yt video --desc "https://youtube.com/watch?v=yu0HjPzFYnY"
yt v -d "https://youtube.com/watch?v=yu0HjPzFYnY"
yt video --date "https://youtube.com/watch?v=yu0HjPzFYnY"
yt v -D "https://youtube.com/watch?v=yu0HjPzFYnY"
---------------------------------------- ----------------------------------------
USAGE USAGE
---------------------------------------- ----------------------------------------
YT-SEARCH YT
-------------------- --------------------
yt-search lists videos matching a certain search query. `yt` is the shelltube script-- it's executed with a subcommand [arguments]
USAGE: yt-search [-csmb] query system, like `apt` or `git`.
Each option [-csmb] represents a different format-method. USAGE: yt subcommand action [arguments]
-b big TITLE \n DURATION | VIEWS | URL
-m medium TITLE | DURATION | URL
-s small TITLE | URL
-c compact TITLE | ID
Big takes up two lines, while the rest only use one. The subcommands are:
If you're piping output, you might wanna usa -m, -s, or -c. * (v)ideo
* (p)laylist
They refer to actions related to videos and playlists, respectively.
Every subcommand and action thereof supports "-h" and "--help".
YT-DESC
YT VIDEO
-------------------- --------------------
yt-desc prints the description of a YT video. `yt video` is for anything related to videos-- here it is:
USAGE: yt-desc url/id
The only argument it takes is the URL/ID of the video. USAGE: yt (v)ideo [action]
This script requires `lynx`.
Here are the actions:
SHORT LONG ARGUMENTS
----------------------------------------------
-s --search [-csmb] search_query
-t --title url/id
-d --desc url/id
-v --views url/id
-a --author [-nu] url/id
-D --date url/id
The only actions with weird arguments are --search and --author:
* normally, --author returns the channel URL and name on two
seperate lines
* "--author -n" returns only the name
* "--author -u" returns only the URL
* normally, --search prints results in the "big" format (title on
one line, other metadata on second line)
* "--search -c" for "compact" format, etc.
* "-c", "-s", "-m", "-b", for "compact", "small", "medium", and "big",
respectively
YT PLAYLIST
--------------------
`yt playlist` is for anything related to playlists-- here it is:
USAGE: yt (p)laylist [action]
Here are the actions:
SHORT LONG ARGUMENTS
----------------------------------------------
-s --search [-csmb] search_query
-l --list [-csmb] url/id
-t --title url/id
-v --views url/id
-a --author [-nu] url/id
-D --date url/id
The only actions with weird arguments are --search, --list and --author:
* --author acts just like "video --author"
* --search acts just like "video --search"
* --list acts just like --search, with [-csmb]
YT CHANNEL
--------------------
`yt channel` is for anything related to channels-- here it is:
USAGE: yt (c)hannel [action]
Here are the actions:
SHORT LONG ARGUMENTS
----------------------------------------------
-s --search [-csmb] search_query
-l --list [-csmb] url/id
-t --title url/id
-d --desc url/id
-v --subscribers url/id
-D --date url/id
The only actions with weird arguments are --search, --list and --author:
* --search acts just like "video --search"
* --list acts just like "playlist --search"

SHELLTUBE Shell scripts for easy YT-browsing
===============================================================================
shelltube is a collection of (pretty POSIX) shell scripts to
browse YouTube quickly, and entirely without captive UIs.
shellTube is written in pure shell; its only dependencies
are any modern shell (pdksh, bash, zsh) and curl/wget/ftp.
Your terminal should accept ANSI color-codes, too~
----------------------------------------
USAGE
----------------------------------------
There are three different scripts that make up shelltube:
* yt-search
* yt-channel
* yt-meta
In all three scripts:
'index' means what page of results you're on--
'results' means how many of them will be displayed.
yt-search lists videos matching a certain search query.
USAGE: yt-search [-i index] [-r results] query
yt-channel lists the videos of a given channel.
USAGE: yt-channel [-i index] [-r results] URL/ID/name
yt-meta lists the metadata of a given video
USAGE: yt-meta URL/ID
