argv -- C Language Argument passed to main() char *argv[]; argv is an abbreviation for ``argument vector''. It is the traditional name for a pointer to an array of string pointers passed to a C program's main function; by convention, it is the second argument passed to main. By convention, argv[0] always points to the name of the command itself. Example This example demonstrates both argc and argv[], to recreate the command echo. main(argc, argv) int argc; char *argv[]; { int i; for (i = 1; i < argc; ) { printf("%s", argv[i]); if (++i < argc) putchar(' '); } putchar('\n'); exit(0); } See Also argc, C language, envp, main() ANSI Standard, §5.1.2.2.1
