An Overview of Source Command in Linux with Examples ?

This article covers how to use the source command in Linux. source reads and executes commands from file filename in the current shell. If filename does not contain a slash, directories in PATH are searched for filename.

Using source to execute the commands in a file is not the same as running a script. For one thing, the file does not need to be executable (e.g., with chmod u+x). For another, the commands will execute in the current shell environment; for example, any variables set will retain their value after the source is finished executing.


Source Command Syntax

The source command uses the following syntax:

$ source [filename] [arguments]

Where:

  • [filename]: The name or path to the file you want the source command to execute.
  • [arguments]: Any arguments you provide become positional parameters when the file is executed.
