Minimal Bcrypt Hash Generation on Debian/Linux

Generate a valid bcrypt password hash on a minimal Linux installation using standard Perl without installing any additional packages or Perl modules.

How It Works

Standard Linux distributions (like Debian/Ubuntu) include libxcrypt/glibc, which natively support bcrypt through the system C library crypt(3).

Perl's built-in crypt() function directly delegates to this system library. By formatting a 22-character salt with the $2b$ prefix, Perl handles bcrypt natively out of the box.

`yq` command to find the full path by a key name – (using the go implementation by mikefarah/yq)

TL;DR

yq '.. | select(tag != "!!map" and tag != "!!seq" and (parent | key) == "<keyname>") | path | join(".")' \
 <filename.yaml>

Example

MP4 Total Duration in Hours

Calculate the total duration (in hours) of all MP4 files in the current directory and its subdirectories.

Requires the ffprobe utility (part of FFmpeg) to be installed.

find . \
  -type f \
 -iname "*.mp4" \

Synology drive download unsynced due to invalid file name or attribute

Usage:

chmod +x syno_check.sh
./syno_check.sh /path/to/your/synology/sync/folder

Remove old linux kernels

Script way

# Dry run to check
bash remove-old-kernels.sh

# Run
bash remove-old-kernels.sh exec

Pure ESM package

The package linked to from here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

Use ESM yourself. (preferred)
Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
Stay on the existing version of the package until you can move to ESM.

	# Configuration (can be modified here directly)

	# For standalone, let's use simple echo with prefixes instead of log_warning/log_info
