RTR's Super ReadyPak: The GAWK Manual


The #! mechanism works on Unix systems derived from Berkeley Unix, System V Release 4, and some System V Release 3 systems.


The line beginning with #! lists the full pathname of an interpreter to be run, and an optional initial command line argument to pass to that interpreter. The operating system then runs the interpreter with the given argument and the full argument list of the executed program. The first argument in the list is the full pathname of the awk program. The rest of the argument list will either be options to awk, or data files, or both.


Since all variables in awk are global, this program uses the common practice of prefixing the variable name with an underscore. In fact, it also suffixes the variable name with an underscore, as extra insurance against using a variable name that might be used in some other library file.
