The LIBPATH command either sets or displays the value of the LIBPATH environment variable. With no argument, it writes the value of the variable to its standard output, in the form "LIBPATH=value". With an argument, it sets the value of the variable to that argument.
Note: On IBM OS/2, the library path is not an environment variable. It cannot be modified after the operating system has booted. Nor can it be displayed with commands that report the process' environment.
