From a749414f16d0871d7e430460d396334b57784319 Mon Sep 17 00:00:00 2001 From: Jim Warner Date: Sun, 27 Feb 2022 00:00:00 -0600 Subject: [PATCH] top: tweaked the recently introduced 'STARTED' support When the 'STARTED' field was added, the width was made the same as the 'TIME+' field. Thus, a full time could be shown (which then included hundredths of a second). That kind of granularity is totally unnecessary. After all, this column is potentially confusing enough since it is so counterintuitive. So, this commit will reduce the width of the field with some help from scale_tics. Henceforth it will not include those ol' centiseconds. [ along the way let's expand the man document with a ] [ a remainder about content representation & scaling ] Reference(s): . introduced 'start time' field commit 7647e96b0a35d473fa9bc644ea6107487b3b0527 Signed-off-by: Jim Warner --- top/top.1 | 7 ++++++- top/top.c | 14 +++++++------- top/top.h | 2 +- top/top_nls.c | 2 +- 4 files changed, 15 insertions(+), 10 deletions(-) diff --git a/top/top.1 b/top/top.1 index 61d62fd3..d448d7eb 100644 --- a/top/top.1 +++ b/top/top.1 @@ -980,10 +980,15 @@ member of the session, called the session leader, which is usually the login shell. .TP 4 -\fBSTARTED \*(Em Start Time \fR +\fBSTARTED \*(Em Start Time Interval\fR The length of time since system boot when a process started.
