Windows Information Passing (pipe into REBOL standard input)

Hi, this was discussed here some time ago. Pipe on the command line works in Windows 95, NT 4 and 2000 as shown in the following example, but Windows 98 prints a cryptic error message "Intermediate file error during pipe", I could not find the cause of this. command.com in both Windows 95 and 98 internally implements the | semantics with temporary files in %TEMP%, but "cmd.exe" in NT or 2000 uses real pipes. Since you mention "ipconfig /all", you probably have NT or 2000 so it should work. The important thing is that piping input into REBOL works only when output is piped to some command as well. AFAIK there are no "no-op filters" in Windows like UNIX "cat" or "tee", but I discovered that "more" can be used if REBOL output is less than a page of text, or better "findstr ." in Windows NT or 2000. The example (paste into the command line as one line, including the trailing dot): Microsoft Windows 2000 [Version 5.00.2195] (C) Copyright 1985-2000 Microsoft Corp. C:\>ipconfig /all | rebol.exe -wq --do "print {REBOL from stdin: } while [ line: pick system/ports/input 1 ] [ print line ] quit" | findstr .

Yes, that helps a lot! Thanks. Now I just need to parse out the MAC addresses, and I'm home free. gary Quoting Michal Kracik ([michal--kracik--net]):
