I think the default for less is not to have --use-color set, so that is probably why it didn't work for you. I set it on login. This could be put as a function in .bashrc so that invoking something like jrctl would run it automatically. I'm not sure how that would work for the OP who wanted to use cat though. I tried $ SYSTEMD_COLORS=16 journalctl -r | sed 's/\x1b\[0;34m/\x1b\[0;31m/g' | cat - and it worked to send the output colored correctly to stdout, but there was no paging, it just was a continuous stream. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
