[Crash-utility] [PATCH] Suppress lkcd_speedo() spinner in redirected output

When redirecting output to a file or script the 'spinner' written by the lkcd_speedo() function complicates parsing output. Currently the spinner is only suppressed if crash is run with the '-s' option or the command 'set silent on' has been executed. The change in this patch suppresses the spinner when the output is redirected to a pipe or file. ---- diff -Nurp crash-7.1.0//lkcd_common.c crash-7.1.0+//lkcd_common.c --- crash-7.1.0//lkcd_common.c 2015-02-06 12:44:11.000000000 -0600 +++ crash-7.1.0+//lkcd_common.c 2015-02-11 13:50:11.000000000 -0600 @@ -623,7 +623,8 @@ lkcd_speedo(void) { static int i = 0; - if (pc->flags & SILENT) { + if (pc->flags & SILENT || + pc->redirect & (REDIRECT_TO_PIPE | REDIRECT_TO_FILE)) { return; }
