 Posted: Fri Mar 20, 2020 12:54 pm Post subject: [solved] journalctl output color codes messed up |
 |
|
I have a Gentoo VPS where I use systemd/journalctl, as I do on my laptop. On my laptop, colored output of journalctl works as it should. When ssh'ing into my VPS and looking at colored output, the color codes show, seem duplicated and some colors are shown and some are not. When consulting man pages, no such issue exists.
Example output from VPS (on every line everything after the first '245m' is red):
| Code: | kernel: ^[[0;38;5;245m^[[0;38;5;245me820: update [mem 0x00000000-0x00000fff] usable ==> reserved

The ‘corresponding’ lines in my latop's journal (the lines with color above are now colored gray, as they should be):

I have another VPS (with Ubuntu), where the journalctl output is properly colored.
What might be the issue on my Gentoo VPS setup. I'm assuming it is some misconfiguration, but have no clue where to start looking.

I discovered it myself: on my VPS I hadn't set SYSTEMD_PAGER to /usr/bin/less, but my PAGER was used (most). So to fix it, I added a file systemd_pager.sh to /etc/profile.d with as contents | Code: | | export SYSTEMD_PAGER=/usr/bin/less |
