Modifying the path variable in linux machine

Hello all, we often need to modify the environment path setting to access our most used programs easily or to make them available to run from anywhere in the system so that dependent components can make use of them.

Usually, in a Windows machine, you have the comfort of setting the PATH by going into the System Properties -> Environment Variables and adding in a new entry, making your life easier.

But when people are changing from Windows to Linux environments, they find it difficult at least new comers to modify / tweak the path setting. So, I am writing this post to show you how to add your favourite programs to path in a Linux Machine.

In the Linux Machine Home(/home/username) directory, you have 2 files .bashrc and .profile. These 2 files manage the path entries in linux system. You can see these files in a file explorer by enabling hidden files. Press Ctrl + H in a folder to show your hidden files in the file explorer.

You can open the above files in your favorite file editor. You need to make an entry in the PATH variable which usually present at the end or somewhere in the file. In Windows, each path entry is separated with a ; In linux, each entry is separated by a colon :

Suppose you have an executable in a folder, copy the path to the folder and append it to the existing path. After adding the entry, you need to logout and login into the PC.

So, what is the catch in editing .bashrc and .profile both? The programs in the .bashrc are available only in the command line or terminal. Suppose if you want to run the program from a GUI like run prompt you see in windows, Alt + F2 in ubuntu, you have to make the change in .profile

If you want to make the program to be accessible only in Terminal mode, make entry in .bashrc
If you want to make the program to be accessible in both Terminal and GUI, make entry in .profile

I hope this post makes some sense and helps some one. Thanks :)

Changing the lock screen wallpaper on CM12 or CM13

CYANOGENMOD provides a cool feature to apply themes system wide. But these themes have option to change the lock screen wallpaper too. After applying the theme, there is no way to revert back to the original lock screen wallpaper if it is deleted or applying another theme unless the new theme supports changing lock screen wallpaper.

The inbuilt theme doesn't have option to apply lock screen wallpaper, it uses the home screen wallpaper as lock screen wallpaper.

If you installed a theme and it had changed your lock screen wallpaper and you want to restore it, follow the simple steps below.

1. Go to Settings -> About Phone, tap build number continuously and enable developer options.
2. Go to Developer Options and enable the inbuilt terminal in the developer options.
3. You also need to have root access enabled in the developer options.
4. Open the terminal application visible in the launcher.

Type the below commands in the terminal application to restore the wallpaper.

1. su (This will prompt for root access or super user permission, give root access to terminal)
2. cd /data/system/users/0
3. rm keyguard_wallpaper
4. ln -s wallpaper keyguard_wallpaper
5. chown -h wallpaper keyguard_wallpaper

BOOM..!! Now you have set your current wallpaper to lock screen wallpaper, now enjoy your CYANOGENMOD like you were using previously.

This thing works not only on CM12 or CM13, it should work on any Android Phone with any version, but all you need is Root access in your phone.

Thanks :)
