https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217159 Conrad Meyer <cem@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Assignee|freebsd-bugs@FreeBSD.org |cem@freebsd.org CC| |cem@freebsd.org --- Comment #1 from Conrad Meyer <cem@freebsd.org> --- Some history on this one. This dates back to an improvement by "bloom@" (Jim Bloom?) in BSD in 1985 to use the terminal's size: > get screen width ioctl added and hold passwd file open https://svnweb.freebsd.org/csrg/bin/ps/ps.c?r1=3D18105&r2=3D18106&=20 Prior to that, it was hardcoded at 80. Kirk McKusick merged 5.4.1.1 (of what, I'm not sure), which changed the ioc= tl to check stdout instead of stdin (CSRG r27213). In 1990, marc@ added the fallback checking for stderr, stdout, and stdin, a= nd dropped the width from 80 to 79, as you see today. The commit log was... terse: > new version https://svnweb.freebsd.org/csrg/bin/ps/ps.c?r1=3D40675&r2=3D40674&pathrev= =3D40675 It hasn't changed significantly since. --=20 You are receiving this mail because: You are the assignee for the bug.=
