A relatively easy implementation would be to fiddle shell commands: if (LASTCHAR(p) == '|') error(FATAL_RESTART, "pipe to nowhere?\n"); to interpret pipes to nowhere to, instead, be redirecting to a mkstemp file that gets read back in via an internal: sprintf(pc->command_line, "< %s", tmp_file); after the command completes, and unlink(tmp_file); after *those* commands complete. What you already have works. It's that this would be slick :). It would make shell scripting into a crash extension language. -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/crash-utility
