Rebooting a Linux server unattended – twm’s blog

Posted by jpluimers on 2020/09/21

[WayBack] Rebooting a Linux server unattended – twm’s blog:

/sbin/shutdown -r now

Simple, but I keep forgetting where Linux has short/long command options and short/long verbs.

I need to dig into IPP / driverless printer confuguration

Posted by jpluimers on 2020/09/07

It looks like I need to learn about IPP and driverless based on [WayBack] TIL that your Linux desktop can probably use your somewhat recently made printer, efficiently, with all major features exposed, without needing to download a ton of vendor shitware, without needing to find a PPD file in the depths of hell, without needing to pay extra for explicit PostScript 3 support, and without needing to accept that it will do 0.2 instead of 20 pages per minute because the in-printer PostScript rasterizer runs on a Z80…. – Maik Zumstrull – Google+.

So here are some links:

When adding my printer in the Chrome tool, it can properly detect it:

Printer information
Printer make/model: OKI-MC342-36855D
Printer state: idle
Accepting jobs: true
IPP server version: 1.1
Supports PDF natively: true
Supports PWG raster: false
Supports Postscript: true
Supports Unirast: true
Supports application/octet-stream: true
CUPS server: No
Compatability report: PASS Printer should be compatible – try printing

bash – convert comma separated values into a list of values using shell script – Stack Overflow

Posted by jpluimers on 2020/09/07

For a simple comma separated list (no quotes), I was expecting a sed script (and indeed it is possible), but tr is more elegant:

Use tr to change , into newlines:

tr , "\n" < list.txt

See https://en.wikipedia.org/wiki/Tr_(Unix)

find – display only files starting with . (hidden) – Unix & Linux Stack Exchange

Posted by jpluimers on 2020/08/21

find . -type f -name '\.*' -print

Must work if you want list every hidden file down in the directory hierarchy.

This sort of works on Linux, but fails on VMware ESXi (on Linux it only works when applying -maxdepth 1, deeper levels fails because they list all files where the top directory starts with a .):

If you want hidden files and hidden directories, without . and .. :

find -regex '\./\..+' -print

This works on both Linux and VMware ESXi:

If you want hidden files and hidden directories, without . and .. :

find . \( -type f -o -type d \) -name '\.*' -print

Based on:

Dirvish

Posted by jpluimers on 2020/08/17

I think it was Thomas Mueller pointing to this, but I’m not sure as I found it in a browser tab from long ago: [WayBack] Welcome to Dirvish

Dirvish is a fast, disk based, rotating network backup system.

With dirvish you can maintain a set of complete images of your filesystems with unattended creation and expiration. A dirvish backup vault is like a time machine for your data.

Dirvish was originally created by jw schultz .

Before starting, I want to read these:
