    Command:

    program_invocation_short_name

    
    
    
    

    SYNOPSIS

           #define _GNU_SOURCE         /* See feature_test_macros(7) */
           #include <errno.h>
    
           extern char *program_invocation_name;
           extern char *program_invocation_short_name;
    
    
    

    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.
    
    
    

    CONFORMING TO

           These  variables are GNU extensions, and should not be used in programs
           intended to be portable.
    
    
    

    NOTES

           The Linux-specific /proc/[number]/cmdline file provides access to simi-
           lar information.
