For a command like this one on Linux debian-linux 4.19.0-1-amd64 #1 SMP Debian 4.19.12-1 (2018-12-22) x86_64 GNU/Linux with xfce I get :
alain@debian-linux:~$ dbus-send --system --type=method_call --print-reply --dest
=org.freedesktop.DBus /org/freedesktop/DBus org.freedesktop.DBus.ListActivatable
Names
The same command on OpenBSD LeOpenBSD 6.4 GENERIC.MP#364 amd64 with xfce I get :
ktop/DBus org.freedesktop.DBus.ListActivatableNames <
On linux, at the end of screen, we go to next line.
On BSD(OpenBSD-NetBSD), the command line continue on the same line and the first words disapear.
It's the same in xfce-terminal-emulator, xterm or in TTY (Alt-Ctrl-F3)
I try to add am in gettytab in the defaut section with no avail.
Termcap man page say :
If the display wraps around to the beginning of the next line when the cursor reaches the right margin, then it should have the am capability.
What can I do ?
I think what you're actually describing may be a difference between the two very different shells used on Linux and most BSDs and their very different command-line editing implementations.
This probably has nothing to do with differences between various terminal emulator implementations; nor with differences between terminal capabilities databases describing those terminal emulations.
On the BSD system(s) the default shell's command-line editor scrolls the whole like across the width of the screen depending on the position of the cursor. On some Linux systems I've seen the default shell's command-line editor wrap long lines around to continue on the next line.
