https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=258409 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 environment. This can be easily reproduced: $ env TERM=dumb 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 = 0 doesn't seem like it would ever be what someone actually wants. I've reproduced this on 12 13 and CURRENT. -- You are receiving this mail because: You are the assignee for the bug.
