Hide and Unhide Plex Media Servers Libraries

Plex media server is a famous media server, I use it at home to set local media server for myself and family.

However, to be able to hide some Libraries is not straightforward,  as it is not supported by the app itself, and there's a plugin that allows you to do so for 1 Library for free and pay for the others (It called Lock for Plex).

I used this extension and find out how it works, and I hacked it and be able to hide more than one Library.

How "Lock for Plex" work is by updating the database used by Plex.

It uses two bash files, one for lock and the other for unlock:

Plex Media Server/Plug-ins/Lock_for_Plex.bundle/Contents/Resources/lock_support/lock.sh

Plex Media Server/Plug-ins/Lock_for_Plex.bundle/Contents/Resources/lock_support/unlock.sh

Here's the content for myself after I've been modified on this file:

cat lock.sh #!/bin/bash lockplex="UPDATE metadata_items SET metadata_type=20 WHERE library_section_id=2 and metadata_type=1; DELETE FROM library_sections WHERE id=2;" lockplex2="UPDATE metadata_items SET metadata_type=4444 WHERE library_section_id=8 and metadata_type=4; DELETE FROM library_sections WHERE id=8;" cd "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-ins/Lock_for_Plex.bundle/Contents/Resources/lock_support/" ./sqlite3 "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/com.plexapp.plugins.library.db" "$lockplex" ./sqlite3 "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/com.plexapp.plugins.library.db" "$lockplex2" exit; mhewedy@probook:~$ cat unlock.sh #!/bin/bash unlockplex="UPDATE metadata_items SET metadata_type=1 WHERE library_section_id=2 and metadata_type=20; INSERT OR REPLACE INTO library_sections (id,name,section_type,language,agent,scanner,created_at,updated_at,scanned_at,user_fields,uuid) VALUES (2,'English Movies',1,'en','com.plexapp.agents.imdb','Plex Movie Scanner','2016-07-03 07:27:07','2016-07-03 08:35:21','2016-07-03 08:35:21','pr%3AenableCinemaTrailers=0&pr%3AincludeInGlobal=0','c07640f7-a137-4987-95ba-c3c5850383d3');" unlockplex2="UPDATE metadata_items SET metadata_type=4 WHERE library_section_id=8 and metadata_type=4444; INSERT OR REPLACE INTO library_sections (id,name,section_type,language,agent,scanner,created_at,updated_at,scanned_at,user_fields,uuid) VALUES (8,'TV Shows',2,'en','com.plexapp.agents.thetvdb','Plex Movie Scanner','2016-07-07 03:45:33','2016-07-07 03:45:55','2016-07-13 21:03:02','pr%3AincludeInGlobal=0','0d670ea9-0da4-4639-8f52-2fcd64f3d8c8');" cd "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-ins/Lock_for_Plex.bundle/Contents/Resources/lock_support/" ./sqlite3 "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/com.plexapp.plugins.library.db" "$unlockplex" ./sqlite3 "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/com.plexapp.plugins.library.db" "$unlockplex2" exit;

One other way to achieve the same result is to have some other disk partition and mount it on-demond.

Ifelse shortcut

if (testCondition() && executeMe() || executeMeOtherwise());

Origin come from bash, to execute if else on a single line:
[ $# == 0 ]  && echo 'invalid input' || processInput($*)
If no parameters passed, the echo 'Invalid input' else, start processing the input.

continually monitor CPU usage for a command

cmd=[m]oviecrawler;while :; do echo -ne "CPU: `ps aux | grep $cmd | awk '{print $3}'`\\r" ;  sleep 1; done

refactor (find and replace in files)

If you want to refactor (find and replace in files) , you could use the following script (on your own)

Periodically change the background of Linux desktop

I've wrote a script that periodically change the background of your Linux desktop.

The script and installation description are on github=> bg_cycle

Have fun!

Convert Jar files to executables on Linux

After finished the image-downloader, I find it very funny to use it to crawl the site to download different backgrounds!

But I find it uncomfortable if I use it as Java jar, so I needed to either wrap it in some shell script (very easy), or convert it into some shell executable, so to forget about the JAR file at all.

I found this command to convert any JAR to shell executable (instead of just wrapping it):

(echo '#!/usr/bin/java -jar'; cat blahblah.jar) > blah
(echo '#!/usr/bin/java -jar'; cat ImageDDL.jar) > imageddl; chmod +x imageddl

It is very awesome!

BTW, You can download the Linux executable from here imageddl!

jboss7_mod_util

Because the "modules" in jboss7 is the worst thing ever, it like manage maven dependencies by hand...

I decided to write some shell scripts to help me manipulate and organize the modules..

The first script is "mod_create", to create a module....
the second script is "mod_dependency_add", to add module dependency to existing module...

My plan is to add additional scripts for example ...

"mod_modify" to add jars to existing module

Any contributions are welcome .....

The project is on github at:

Thanks.

Shell: a script file to search a directory of Jars about which jar cointains which file?

Hi folks,

Today I am coming with some shell script that is useful if you want to need to know from a group of Jars in certain directory which one of them contains a certain file (Java class)

#! /bin/sh

path=$1
segment=$2

if [ -z "$path" ] || [ -z "$segment"  ]
then 
    echo "Usage: $0 <path> <segment>"
    exit
fi

for jar in $path/*.jar ; do echo " *** $jar *** " ; jar tf $jar| grep --color=always $segment; done;
