Command Line Magic

Is the post-mis-information age going to be any better?

It's a form field that asks for Today's Date

Bad UX design demonstrated in one form field.

It's funny how humans complain about AI hallucinations when humans make shit up all the time.

Vim users: If you'd like to highlight the whole line the cursor is on:

:set cursorline

I just used that when examining package output from dpkg -l so that I could easily see which description matched each package.

Being able to do stuff like this is what makes the command line pretty special:

ssh 192.168.0.15 'sudo dd if=/dev/sda bs=1M status=progress' > backup-old-drive.img

It's a clipart meme image with the first character saying "LInux: You can copy a file with the 'cp' command. and the 2nd character responding "THAT'S TOO HARD!". Then the next characters with beards. The one on the left asks "Sharepoint: How can I copy a file?" and the one of the right just responds "No."

All I wanted to do was copy a file.

This Minecraft MMO server has "command line terminals" in it. Non-functional, but I approve.

Couldn't help but notice the lunar eclipse tonight at least in eastern time zone is π (3.14159) as in March 14th in the 159th minute of the day (2:39am)

I tried to do standup comedy once.
But, by the time I finished editing the joke,
the audience was already walking out and
my computer was all over the floor.

Text from page 7-36 of the AmigaDOS manual, it has hotkeys that mimic Emacs keys and it talks about the characteristics of the shell.

I had forgotten how unixy the Amiga shell is.

If you mistakenly use curl like nc like the following:

curl www.example.com 80

the port number ends up being treated as an IP address of the form 0.0.0.N. So if you see traffic destined to 0.0.0.80, 0.0.0.22, etc. on your network, it's probably someone messing up their curl command.

Today I learned that not only Libreoffice didn't have a unique() function until recently, but apparently Excel didn't even have it until 2018. This is like 30 years later than you'd expect spreadsheets to implement it. Unix had it in 1982 as Brian Kernighan shows here www.youtube.com/watch?v=tc4R...

If you're concerned about how your use of wildcards and brace expansion will be interpreted by the shell and passed to the program, you can usually replace the command name with echo first to get a list of the args that will be generated:

echo Photos/\[Conference\]-*.{jpg,mp4}

If you're not sure what type of data is in a gzip, bzip2, or xz format file, one way to find out is to pipe its decompressed output into the 'file' command:

gzip -dc unknown-gzip-file | file -

It will tell you the type of file data that is inside. The -dc options also work with bzip2 and xz

I ran this yesterday to solve a CTF. It should have been called a WTF.
xxd -r data.txt | gzip -cd | bzip2 -cd | gzip -cd | tar x -O | tar x -O | bzip2 -cd | tar x -O | gzip -cd

Every Unix is sacred, every Unix is best.
Every Unix is different, when you run ps.
