Man Pages | ManKier (converted to HTML5 from troff or mdoc); TLDR pages for many command-line examples

Posted by jpluimers on 2026/10/05

This archive seems to have very recent HTML5 renderings of many man pages from their troff or mdoc sources: [Wayback/Archive] Man Pages | ManKier.

I bumped into it via [Archive/Archive] ipmitool: utility for controlling IPMI-enabled devices | ipmitool Commands | Man Pages | ManKier when writing Some links on Dell R730xd fan noise.

The site is not only very up-to-date on rendered man pages, but the rendering has great features too. Read more on those at [Wayback/Archive] About | ManKier.

A nice history on how ManKier came to be is at [Wayback/Archive] Blog – ManKier. It’s less than a dozen posts, and recommended reading.

Oh, I almost forget: I have added the man search shortcut to my browsers; these two examples should get you going by adding www.mankier.com/?q=%s as a search template:

Some links on Dell R730xd fan noise

Posted by jpluimers on 2026/10/02

Some combinations of hardware/OS will result in high FAN speed despite low power usage on Dell R730/R730xd systems.

For me, altering the BIOS or iDRAC thermal settings did not solve it, nor did updating all firmwares to the most recent versions, so I went digging further.

Below are some links in case I want to resolve that (after figuring out that Dell R730 and R730xd are 13G systems).

There are lots of quotes in them as it will help me find back the information later on.

Note to self: I really wonder what the difference between raw 0x30 0xce and raw 0x30 0x30 is (I think 3rd party PCIe support and forced fan speed level) and how they differ from the system.thermalsettings.ThirdPartyPCIFanResponse setting.

Installing Poppler on Windows via Chocolatey, which includes pdfimages for lossless extraction of images from PDF files

Posted by jpluimers on 2026/03/09

At the time of writing there was an almost 3 year old [Wayback/Archive] Chocolatey Software | Poppler 0.89.0 version so I filed the issue [Wayback/Archive] poppler 23.03 has been out for a few weeks, can you please update the build? · Issue #88 · chtof/chocolatey-packages mentioning [Wayback/Archive] Pull requests · oschwartz10612/poppler-windows

Poppler 23.03.0

Since that did not get really solved, I finally found out that after installing scoop, then scoop install poppler did work and installed version 23.08.0 (which I documented in [Wayback/Archive] Poppler version out of date · Issue #75 · chtof/chocolatey-packages installs from the most recent [Wayback/Archive] Releases · oschwartz10612/poppler-windows).

A very different approach is to install Poppler inside Windows Subsystem for Linux (WSL) as explained in [Wayback/Archive] Poppler On Windows. Python, PDFs, and Window’s Subsytem for… | by Matthew Earl Miller | Towards Data Science.

I needed Poppler (or actually the Windows equivalent of poppler-utils) of two reasons:

  1. I wanted to experiment with pdftotext as it has these very compelling command-line switches.
  2. I needed to export images for which pdfimages is the poppler tool to go.

pdftotext

Let’s start with qoutes from [Wayback/Archive] pdftotext: Portable Document Format (PDF) to text converter (version 3.03) | poppler-utils Commands | Man Pages | ManKier:

GitHub – kellyjonbrazil/jc: CLI tool and python library that converts the output of popular command-line tools and file-types to JSON or Dictionaries. This allows piping of output to tools like jq and simplifying automation scripts.

Posted by jpluimers on 2023/10/17

I already knew about jq and jo (output: the echo for JSON), but not yet about jc for JSON.

Like jq is for querying (the sed for JSON), jc tries to be the universal parser of common command-line tools into JSON:

[Wayback/Archive] kellyjonbrazil/jc: CLI tool and python library that converts the output of popular command-line tools and file-types to JSON or Dictionaries. This allows piping of output to tools like jq and simplifying automation scripts.

Via [Wayback/Archive] Kris on Twitter: ““Jc” verwandelt den Output von üblichen Linux Kommandozeilen Tools in JSON. “Jc” kann auch als Import in Python Programmen verwendet werden und mit subprocess kombiniert werden. Danke, ⁦@janwalzer⁩ und ⁦@the_mutax⁩ für den Tip. “

A few weeks later though, Kris discovered that command-line tools aren’t that portable in their output format: [Wayback/Archive] Kris on Twitter: “As much as I love the idea of @kellyjonbrazil’s jc, this is not a winnable game. sigh Probably still better than a self-cooked parser, but the slightest bit of extra makes it catch fire in multiple possible ways …”
