Add new path to path variable linux

To add a new path to the PATH variable in Linux, you can follow these steps:

Method 1: Using the export command

1. Open a terminal and type the following command:

   export PATH=$PATH:/new/path

   Replace /new/path with the actual path you want to add.

Method 2: Using the export command with a permanent change

1. Open a terminal and type the following command:

   export PATH=$PATH:/new/path
   echo "export PATH=$PATH:/new/path" >> ~/.bashrc

   This will add the new path to the PATH variable and also update the ~/.bashrc file, which is a configuration file that is read by the shell when it starts.

Method 3: Using the export command with a system-wide change

1. Open a terminal and type the following command:

   sudo export PATH=$PATH:/new/path

   This will add the new path to the PATH variable system-wide, which means it will affect all users on the system.

Method 4: Editing the ~/.bashrc file

1. Open the ~/.bashrc file in a text editor:

   nano ~/.bashrc

2. Add the following line at the end of the file:

   export PATH=$PATH:/new/path

3. Save the file and restart your terminal or run source ~/.bashrc to apply the changes.

Method 5: Using the update-alternatives command (for system-wide changes)

1. Open a terminal and type the following command:

   sudo update-alternatives --install /usr/bin/path path /new/path 1

   This will add the new path to the PATH variable system-wide and make it the default.

Note: The update-alternatives command is used to manage alternatives for commands, but it can also be used to add new paths to the PATH variable.

After adding the new path, you can verify that it has been added by running the following command:

echo $PATH

This will display the updated PATH variable.
