Description

program_invocation_name contains the name that was used to invoke the calling program. This is the same as the value of argv[0] in main (), with the difference that the scope of program_invocation_name is global.

program_invocation_short_name contains the basename component of name that was used to invoke the calling program. That is, it is the same value as program_invocation_name, with all text up to and including the final slash (/), if any, removed.

These variables are automatically initialized by the glibc run-time startup code.

Versions
