Hi,
I recently switched form an image based on fsl-image-qt5 to one based on
core-image-base.
The new image works fine in every regard except that the output of some
commands looks weird.
I have attached the output of commands "nmcli" and "systemctl status dbus".
Once executed on the fsl-image-qt5 based system and once on the core-image-base
based system (_weird.txt).
There are two main points I gather from that weird output:
1. There are some codes like "[[32m"+"[[0m" or "[[0;1;32m"+"[[0m", which I
assume are colour codes, that are printed and not applied.
2. The output appears to be opened in a vi-like editor?! It clears and fills
the entire terminal page and seems to display an input mode at the bottom.
Both of these aspects are non-existent on the fsl-image-qt5 based system.
There, colours are displayed normally and the output is just printed right
beneath my command call.
I have discovered that I can get these two commands to work properly on the
core-image-base based system, if I pipe their output into cat: "nmcli | cat".
My assumption for the colour codes is that, the core-image-base system uses a
different text encoding, or a different style of colour codes and therefore
does not recognize the ones presented by nmcli.
I have tried to install the ttf-dejavu-* fonts that are present on the
fsl-image-qt system. I also verfied that both systems seem to be using POSIX as
their LANG setting ("locale" produces the same output on both).
I have no idea why the output is presented in what seems to be a vi editor
though. Both systems have their EDITOR variable set to "vi".
Am I missing some kind of package or setting in my image?
I am at my wits' end and would greatly appreciate anyone trying to shed some
light on what is going on here.
