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 "$@" |grep -v ':0$'
}

#unix #UnixShell #ShellScripting #bash #ksh

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"
}

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.

#ShellScripting

quicktipp #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"

#bash #linux #alias #curl #html #shellscripting #shell

Just three new bash #functions I don't know why I didn't write months/years ago ;)

function binfind {
    #search for patterns in the system bin directories
    local d oIFS="$IFS"
    IFS=:
    for d in $PATH; do
        ls -1 $d/$@ 2>&-
    done
    IFS="$oIFS"
}

function tootlookup {
    #Show a fediverse thread when given a url
    url="$*"
    [[ $url == http* ]] || ( warn "please specify URL"; return 1 );
    toot --no-color thread $(toot --no-color search "$url" |awk '$1=="*" {print $2}' |head -1)
}

function colors {
    #uses ImageMagick identify to print the number of colors in a specified image
    local oIFS="$IFS" output maxlen=0
    IFS=$'\n'
    for f in $@; do
        (( ${#f} >> maxlen )) && maxlen=${#f}
    done
    ((maxlen+=4))
    for f in $@; do
        printf "%-${maxlen}s " $f
        output=$(identify -verbose $f |& grep Colors: |sed 's/^ *Colors: //')
        [[ -n $output ]] || output="(unknown)"
        echo $output
    done
    IFS="$oIFS"
}

Ahh, seems like vm.stats.vm.v_active_count is the closest to what I want in terms of RAM actually used by processes then, thank you both!! :D

Wait, spoke too soon. XD
Still working it out...

Ok,

echo $(( ($(sysctl -n vm.stats.vm.v_active_count) + $(sysctl -n vm.stats.vm.v_inactive_count) ) * $(sysctl -n hw.pagesize) /1048576 ))

...seems to get me the closest to what I want, and closely matches what systat -vmstat displays, as well as top "Active" + "Inact", although btop disagrees and shows about half as much. XD

Ok guys, I got it. ;)

Is there any framework to create shell scriprs?

I'm getting the nerves with so much shell-foo.

I use git in a shell because that's just what I prefer, and I have a lot of aliases set up to shorten commands, e.g. just "g" will be git commit, "gp" is git push etc.
I just realized that this also gives me some safety. I use PageUp to complete the currently typed thing to the last command I executed that starts the same. This will never wrongly complete my aliases to something like "git reset" because I do not have aliases for that and none of my aliases start with "gi".

#PSA regarding #GNU #coreutils #sort's unexpected or at least non-intuïtive behaviour of its --unique (-u) option together with --numeric (-n) or --human (-h).

The output of piping something through

sort -nu

might not be equal to the output of piping the same thing through

sort -n | uniq

as it might miss some lines completely. 🤌

And it's NOT documented in the man page, just in the info page.

Liebe Folglinge,

ich suche nach einem neuen Job als #iOS und/oder #macOS Entwickler. Ich spreche #ObjectiveC, #Swift (auch Server-Side) und #SwiftUI und nutze die ganzen Tools drumherum (#Xcode, #Git, #GitHub, #GitHubActions, #ShellScripting etc.). Ich bringe 30 Jahre Berufserfahrung als Software-Entwickler mit, davon knapp 20 im #Apple Ökosystem.

Am Idealsten waere eine #Festanstellung zu 100% remote. Sollte es im Raum #Bregenz oder #Dornbirn etwas geben, dann auch gerne vor Ort.

Ich danke euch fuers Teilen. 🙏🏻
