Thank you,

I'm using Arch Linux and didn't know this, but since I'm aware that
"apt" does not have a stable CLI interface, I wanted to ensure that
"dpkg -l" works. I already used "dpkg" instead of "apt", since even not
all DEB based installs provide "apt", at least not one still supported
Ubuntu release. Running "dpkg -l *jack* | grep ii" in an empty
directory gains nothing over "dpkg -l '*jack*' | grep ii", but I didn't
know that "dpkg -l '*jack*' | grep ii" does work. I'll try to keep this
in mind, OTOH the transition to apt, at least for Ubuntu, already
started, so dpkg soon or later will be obsolet.

Regards,
Ralf
