https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D258409 Bug ID: 258409 Summary: top(1) outputs no processes when TERM is not set Product: Base System Version: 12.2-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: freqlabs@FreeBSD.org We capture the output of top -SHIwz -d 2 in a debug script, but there are no processes shown. The lines for the processes are all blank. Upon investigation, this only occurs when TERM is not set in the environmen= t. This can be easily reproduced: $ env TERM=3Ddumb top -SHIwz -d 2 | cat Processes are listed. $ env -u TERM top -SHIwz -d 2 | cat Blank lines are displayed where processes should be listed. We are working around this issue with -n to force non-interactive mode, but= it would be good to fix top since screen_width =3D 0 doesn't seem like it woul= d ever be what someone actually wants. I've reproduced this on 12 13 and CURRENT. --=20 You are receiving this mail because: You are the assignee for the bug.=
