Change (NEXT or PREV) the songs on the iDevice using volume keys (JAILBROKEN)

If you have a jailbroken iDevice(iPhone, iPad or iPod) then you can use the volume keys to change the songs while playing. You can either Next the playing song or Prev(Previous) the playing song. You just need a simple Cydia tweak known as 'Activator' to do so!

Activator is a simple but very important tweak developed by Ryan Petrich used for defining many tasks for simple gestures. It can be downloaded by adding this repo:

NOTE: 

• The above process will work only on the locked iDevices. 
• Similar process can be carried out to play the previous track. Just tap on 'Down Short Hold' instead of 'Up Short Hold' and 'Previous Track' instead of 'Next Track'.

Change permission of all the contents of a folder in Ubuntu

The method for changing the permission of specific file or folder was discussed in this post. However, if anyone is not allowed accessing multiple files or folder inside a folder then you might be trying the code for every single contents. That's just a waste of time in my opinion. Here's quick method of changing the permission of every contents of a folder:

• Open the terminal: Ctrl+Alt+T
• Change the directory by using the change directory command, 'cd' as:

  cd location/location/.../location

• Type the following codes(here, foldername means the name of the folder whose contents are to be accessed):

  chmod -R 777 foldername
  

• This will give you access to every contents of the folder.

Change permission of specific file or folder in Ubuntu

Sometimes user might not get access to read/write a file or folder. This is due to the fact that the user is not granted full permission to modify them. The simplest method to change the permission for files and folder in Ubuntu are given below:

• Open the terminal: Ctrl+Alt+T
• Change the directory by using the change directory command, 'cd' as:

  cd location/location/.../location

• Type the following codes:

  chmod 777 filename_with_extension/foldername

• This will give you access to the specific file or folder.
