How To Run a Script In Linux

To run a script in Linux, you will need to make the script executable and then run it using the appropriate command interpreter.

Here is the general process for running a script in Linux:

1. Make the script executable: In order to run a script, you will need to make it executable. You can do this by changing the permissions of the script file using the chmod command.

For example, if the script file is named script.sh, you can make it executable by running the following command:

chmod +x script.sh

This will set the executable permission bit on the script.sh file, allowing you to run it as a program.

2. Determine the command interpreter: The next step is to determine the command interpreter that should be used to run the script. This is typically specified in the first line of the script, using a shebang (#!) followed by the path to the command interpreter.

For example, a script that is written in the bash shell might have the following first line:

#!/bin/bash

This specifies that the bash shell should be used to interpret the script.

3. Run the script: Once the script is executable and the command interpreter has been determined, you can run the script by specifying the path to the script file as an argument to the command interpreter.

For example, if the script file is named script.sh and the command interpreter is bash, you can run the script by using the following command:

bash script.sh

Alternatively, you can simply specify the path to the script file on the command line. If the script file is in the current directory, you can use the following command:
