>From 7b9a194fd6d2d2d7d1bc39f28064dd2cb9340aad Mon Sep 17 00:00:00 2001 From: "Yuriy M. Kaminskiy" <yumkam@xxxxxxxxx> Date: Sun, 28 Feb 2016 03:34:13 +0300 Subject: [PATCH] taskset.1: fix description of `-c` option Commit 42f15e9848dc07e86a2b80c742a0179aaced6c71 introduced a certain inaccuracy in -c option description; it is not _the option with an argument_, but it is the flag that changes interpretation of `mask` parameter. The difference is almost not noticeable, but there are one corner case where it is: taskset -c 1 -p $$ fails (but it would work if 42f15e was correct). Instead, taskset -c -p 1 $$ works (but it should not have if 42f15e was correct). --- P.S. argument parsing in taskset (and chrt) is rather unusual and confusing, and I'd voted to change it instead... unfortunately, people/scripts/... already depend on current behavior (and it is not outright broken, just unusual), so it is impossible. schedutils/taskset.1 | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/schedutils/taskset.1 b/schedutils/taskset.1 index 50cbe6b..901f9fa 100644 --- a/schedutils/taskset.1 +++ b/schedutils/taskset.1 @@ -73,9 +73,9 @@ CPU. .BR \-a ,\ \-\-all\-tasks Set or retrieve the CPU affinity of all the tasks (threads) for a given PID. .TP -.BR \-c ,\ \-\-cpu\-list \ \fInumbers -Specify a numerical list of processors instead of a bitmask.
