## 2.12. The tclsh Shell

On the UNIX and Linux operating systems, the tclsh shell included with the Intel® Quartus® Prime software is initialized with a minimal PATH environment variable. As a result, system commands might not be available within the tclsh shell because certain directories are not in the PATH environment variable.
To include other directories in the path searched by the tclsh shell, set the QUARTUS_INIT_PATH environment variable before running the tclsh shell. Directories in the QUARTUS_INIT_PATH environment variable are searched by the tclsh shell when you execute a system command.
