The most important global environment variable that you must set is the PATH variable. This is the variable that tells the bash shell where to find different executable files and scripts. The shell will check the directories listed in the PATH variable for the script you are trying to find.

What is Bash? In short, Bash is the Unix command-line interface (CLI). You’ll also see it called the terminal, the command line, or the shell. It’s a command language that allows us to work with files on our computers in a way that’s far more efficient and powerful than using a GUI (graphical user interface).
CMD is the command line for Microsoft Windows operating system, with command-based features. Powershell is a task-based command-line interface, specifically designed for system admins and is based on the . Net Framework.

For Bash, you simply need to add the line from above, export PATH=$PATH:/place/with/the/file, to the appropriate file that will be read when your shell launches. There are a few different places where you could conceivably set the variable name: potentially in a file called ~/. bash_profile, ~/. bashrc, or ~/.
Linux: Add to PATH Permanently
- Open the .bashrc file using a text editor. The example below uses Vim.

The PATH environment variable is a colon-delimited list of directories that your shell searches through when you enter a command. Program files (executables) are kept in many different places on the Unix system. Your path tells the Unix shell where to look on the system when you request a particular program.
Manipulating your PATH variable
bashrc file. To make the change permanent, enter the command PATH=$PATH:/opt/bin into your home directory’s . bashrc file. When you do this, you’re creating a new PATH variable by appending a directory to the current PATH variable, $PATH .
A bash script is a file containing a sequence of commands that are executed by the bash program line by line. It allows you to perform a series of actions, such as navigating to a specific directory, creating a folder, and launching a process using the command line.
The PATH variable is an environment variable containing an ordered list of paths that Linux will search for executables when running a command. Using these paths means that we don’t have to specify an absolute path when running a command.
When the user executes a command by using the full path, the shell uses that path to find the command. However, when users specify only a command name, the shell searches the directories for the command in the order specified by the PATH variable.
