The PATH is an environment variable in Unix-like operating systems that specifies a list of directories where the system looks for executable files when a command is entered in the terminal.
When you type a command, the shell searches through the directories listed in the PATH variable, in the order they are listed, to find the corresponding executable file.
Example:
You can view your current PATH by running:
echo $PATHThis might output something like:
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/binKey Points:
- Each directory in the
PATHis separated by a colon (:). - You can modify the
PATHto include additional directories, allowing the system to find executables in those locations. - Modifying the
PATHis often done in shell configuration files (like.bashrcor.zshrc).
