This ain't a contest, but below is a sufficiently short lex program to chop off the headers of map files as they are sent out. ----------------cut here-------guillotin.l------------------ %START A B %% {BEGIN A;} [^\000] {} "if " {BEGIN B; printf("%s",yytext);} "export " {BEGIN B; printf("%s",yytext);} "sed " {BEGIN B; printf("%s",yytext);} "cat " {BEGIN B; printf("%s",yytext);} "echo " {BEGIN B; printf("%s",yytext);} [^\000] {printf("%s",yytext);} %% ----------------cut here------------------------------------ All that this little lex program does is throw away all input until it sees a word it recognizes. It then goes into state B and simply transcribes stdin to stdout (hence the name guillotin, it chops off headers :-) I set up cron to wake up every night, go to the usenet maps directory, assert a uucp lock to keep uuxqt from running while I do. For each file in the directory run it through "cat $file | guillotin | sh" mv the output to my real maps directory and rm the usenet map file. After this I run pathailas on the contents of my real maps dir. It was pretty simple and I managed to do it in an afternoon. I'm guess-tamating I spent as much time "re-inventing" a package as I would have spent hunting it down and installing/understanding it. -brad- -- v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v^v Brad Turner 1330 Ashleybrook Ln.
