[gentoo-user] script help - removing newlines
I have text files that are sometimes; property "something" comment "whatever" but sometimes there are newline characters in the comment field; property "something" comment "something something else a third thing" I want to replace any newlines between 'comment "' and the next '"' with spaces so the whole comment is on a single line. How can it be done?

I dug around in the garage and found an old i5 Clarksdale machine that literally hadn't been turned on since we sold a house back in about 2013. Unboxed it, cleaned it up a bit, took out all the old hard drives, the CD and the floppy and put in 2 500GB WD Enterprise drives I had sitting here from a previous upgrade. Darned if the machine didn't boot right up from a FreeNAS (now TrueNAS Core) flash drive. I installed the OS to a second USB thumb drive, booted the machine, created a 500GB ZFS mirrored pool, created a user directory and 3 hours later I'm doing backups. So far it's done 30GB of about 450GB and just seems to be humming along nicely. CPU usage is only about 5% most of the time. The processor is only 2 cores, 4 threads, but most of the time it's only using about 5% CPU. No idea how stable it will be but the computer itself was always a good machine 10 years ago so I'll keep my fingers crossed and see how it goes. I'll be adding a SSD front end cache to the storage pool later this week and will likely move the OS to something internal (SSD or maybe an old HDD) as I don't like the idea of depending on a USB boot. Cheers, Mark Anyone looking for some similar solution so far I really couldn't be happier with how easy it was to get this up and running.

By jove, you’re right. Maybe I’ve written that stuff before I knew about
default values. I checked in that code in September of 2016. And it could
possibly be even much older, because I clean up my config git repository
only very sporadically, as in two or three times a year.

Maybe inexperience? :D
Or sometimes, explicit is better than implicit?

Some drive-by after-the-fact comments:

[ "$RANGER_LEVEL" ] && PS1_JOBS_COUNT="${PS1_JOBS_COUNT}R "
I've taken to using things like the following:
PS1_JOBS_COUNT="${PS1_JOBS_COUNT}${MC_SID:+MC }${RANGER_LEVEL:+R }"
Leverage Bash's (and Zsh's) expansion conditional. If the variable is
set, then expand it to a different value.
${VARIABLE:+alternate text to show if VARIABLE is set}
if [[ -z "$PROMPT_COMMAND" ]]; then
PROMPT_COMMAND=__jobsprompt
else
PROMPT_COMMAND="$PROMPT_COMMAND ; __jobsprompt"
fi
Is there a reason to not simply do the following, eliminating the if
conditional:
PROMPT_COMMAND=${PROMPT_COMMAND:+${PROMPT_COMMAND} ; __jobsprompt}

Nope. Check dmesg. Check syslog. Try launching the game from a terminal. Even Steam games usually give *some* kind of hint.
