No matter how many times I write a shell script it always feels like partaking in an act of arcane sorcery.

The syntax is so unintuitive, but the finished product is enchanting in its beauty. Weird.

As I prepare my Tek talks — “Shell Scriptung for PHP Developers” and “Better Dotfiles” — are there specific issues/aspects you’d like me to cover?

Are there particular challenges you have - or maybe a function you wish you had - when shell scripting using dates/times ?

Bash Tip:

There are 2 ways to create a function in Bash

function hello {

your code here

}

or

hello() {

your code here

}

using the function keyword and the empty parentheses is rendundant

For your shell scripts — what are you using for testing them?

#Bash #CLI #ShellScript #testing

If "#!/usr/bin/env foo" is the preferred #shebang (for portable scripts) in order to find "foo" independent of its path, why isn't the recommended shebang "#!env foo" which would not assume a path for "env" either? 🤔

what do you wish was easier about Bash scripting?

Hey #Unix-y peeps (#AskFedi),

Is there a script somewhere (Perl, preferably, or Python, or even a compiled program) that performs
blah |sort |uniq -c |sort -n
in an efficient manner using a dictionary?
Because sorting everything just to get a count with uniq -c seems very slow and wasteful.

SOLUTION, thanks to JdeBP@tty0.social:
awk '{x[$0]++;} END {for(k in x) {print x[k],k;}}'

I wanted to create a "jukebox" page for my #website where I list albums in my collection.

I could just write in #markdown but if the page gets big enough it'll be a pain.

Besides, I'm a techie by trade, I can automate this. I figure I'll use a #plaintext #database and a #shellscript that looks for two files:

"${BAND}.tsv": tab separated, 2 fields: band name, band description
"${BAND}.psv" pipe separated, 4 fields: year, album, label, MusicBrainz link

Then I can update my #makefile.

testing my "jukebox.sh" shell script in a terminal window. It prints Markdown text to standard output and appears to work.
