Another question for Unix experts - this is a hexdump of a SunOS 4.0.1 install disk for Sun 386i systems. Does anyone recognise the file format? It looks like some sort of file system dump, but I don't think it's a variant of BSD dump(8).

The first fields seem to be (in ASCII) Access permissions, uid, and gid (and later the file/dir name).

#unix #filesystem #backup #disk #sunos #sun #sun386i

Alt...

Are you using X11 or Wayland or sth else?

Will you switch anytime soon?

Why did you choose the thing you choose?

#linux #unix #bsd #wayland #x11

I think in an alternate timeline where Apple didn't exist any longer, BSD/*nix OS's would have had a different outcome. I want to believe it would have been better, for sure.

I will also say: Linux is good right now. Yes, you need to pay attention to hardware choices. Yes, not every program is 1-to-1 with it's counterparts. But even for power users that do lots of coding, it works well. I have access to Firefox, Google Chrome (not just Chromium), VS Code, Discord, etc etc.

So to say it has a lot of the same issues is IMO incorrect because people such as ourselves wouldn't just grab a system off the shelf and then hope Linux works. 1/2

Delivered my "The Zen of Shell Scripting" presentation today. On my intro slide I mention that Shell is often treated as second class because it is "not a real language" and at the same time "too hard to learn".

Seemed like people enjoyed the talk and will take Shell scripting more seriously now. Success!

I even found and reported a small -snap bug in evilwm while testing 🙂

Example wrapper I’m using:

#!/bin/sh
#
# safeedit — RCS-backed safe editing with nvi
#
set -e
if [ $# -ne 1 ]; then
    echo "usage: safeedit <file>" >&2
    exit 1
fi
FILE="$1"
if [ ! -f "$FILE" ]; then
    echo "safeedit: file not found: $FILE" >&2
    exit 1
fi
DIR=$(dirname "$FILE")
BASE=$(basename "$FILE")
RCS_DIR="$DIR/RCS"
RCS_FILE="$RCS_DIR/$BASE,v"
mkdir -p "$RCS_DIR"
chmod 700 "$RCS_DIR"
if [ ! -f "$RCS_FILE" ]; then
    ci -l "$FILE"
else
    ci -u "$FILE" || true
    co -l "$FILE"
fi
exec nvi "$FILE"
