       Watch the syslog in real time and highlight cases of ERROR or WARN showing up in them using grep color. The blank pattern in the regex 'or' will ensure you see all lines.sudo tail -F /var/log/syslog | egrep --line-buffered --color=auto 'ERROR|WARN|$'

       @climagic Weren’t egrep and fgrep deprecated in 2007 and definitely removed a few months ago? Probably better to use grep -E these days.

       @climagic What about `journalctl -f` ? There are good options for filtering the syslog with journalctl.

       @kaip Isn’t journalctl part of systemd? What about distros, like Slackware, and other UNIX operating systems that don’t ship it?@climagic

       @josemanuel @climagic They will have to use something else.

       @kaip Of course, Captain Obvious, but my point was that, when @climagic shows us one-liners, the idea is to make them as universal and portable across distros and operating systems as possible. If you use a systemd-ism, that defeats the purpose.

       @josemanuel @kaip I'm not strictly universal nor always POSIX compliant in my posts. I've stated a few times before that I'm mostly focused on bash on GNU/Linux because that's what I'm mostly familiar with. Bash also has the widest audience on Linux. While I do try to make stuff universal, that's impossible due to all the varieties and the SysV vs. BSD vs GNU split of options. If I know something is specifically GNU, then I try to put a #GNU hashtag in the post.
