Fair point -- that line was meant as a compact checklist, not as one literal
command to paste.

I should have written it more like this:

uname -a ip addr ip route systemctl --failed journalctl -b -p warning..alert
--no-pager | tail -100 df -h lsblk -f

Or, if someone wants one pasteable line, with separators:

uname -a; ip addr; ip route; systemctl --failed; \
    journalctl -b -p warning..alert --no-pager | tail -100; \
    df -h; lsblk -f

The newline version is safer for notes and mail, though. Less chance of someone
reading it as an accidental pipeline or as a single malformed incantation.
