 awk: ignore SIGPIPE Hi, IMHO, awk(1) should ignore SIGPIPE. Currently, if awk(1) get's a SIGPIPE when writing to a pipe, it just dies. With the patch below, it dies, too, but at least you get a reasonable error message. diff -x CVS -rNu ../awk.orig/main.c ./main.c --- ../awk.orig/main.c Thu Dec 30 14:06:17 2004 +++ ./main.c Wed Mar 29 15:05:20 2006 @@ -69,6 +69,7 @@ exit(1); } signal(SIGFPE, fpecatch); + signal(SIGPIPE, SIG_IGN); yyin = NULL; symtab = makesymtab(NSYMTAB); while (argc > 1 && argv[1][0] == '-' && argv[1][1] != '\0') { Sample awk script: #!/usr/bin/awk -f BEGIN { for (i = 0; i < 32768; i++) print "" | "./foo" x = close("./foo") print x } Matching "foo": #!/bin/sh echo foo Any Comments? Ciao, Kili ps: I've some more diffs to awk(1) around, but I first have to sort out what's usable and what is junk or still incomplete.      |
