File this under #shell #functions I should have written years ago:
function grepc {
#Do a grep -c, but skipping files with no results
grep -c "$@" |grep -v ':0$'
}
P.S., the body of the parent #toot was created by a simple #shell #function:
function apod {
#Today's NASA Astronomy Picture of the Day info-fetcher
curl -sL 'https://apod.nasa.gov/apod/archivepix.html' \
|grep -m1 "[0-9][0-9]:" \
|sed 's/^/Date: /;
s|: *<a href="|\nURL: https://apod.nasa.gov/apod/|;
s/">/\nTitle: /; s/<.*$//'
echo
echo "#NASA #Astronomy #PictureOfTheDay"
}

David Cantrell 🏏I've been playing with #ntfy. It seems nifty, but if I'm going to use it to get notifications from a #cron job I want more reliability - I want cron to email me if there's an error sending the notification. And so I wrote a thing: https://github.com/DrHyde/shellscripts/blob/c8ac050e4e1284f6b17d4a20dcdcf5a1d75d2c69/cronntfy.
After pushing I noticed some dead code, left over from an earlier version. And I noticed the "ask #Copilot" thing on Github. So I asked it if all the code was reachable. See follow-up for the impressive results.
Chrisquicktipp #110: Looking at minified html output from curl isn't always fun.
Let's create a simple `htmlcat` bash function around `tidy` (for prettyprint) + `bat` (for syntax highlight) so we can just run
"curl https://example.com | htmlcat"
or
"htmlcat file.html"
