Maintain separate bash_histories and remember the last pwd for each tmux session/window/pane!

This is useful for setting up tmux project sessions with multiple windows and panes. Each time you create a new tmux session with the same name as a previous session, each windows' pane will maintain it's own separate bash_history and pwd!

This is very useful for long-running tmux sessions, especially when something happens to any of the shells. That very complex but useful log tailer that was started 6 months ago? It's the last command that was run ... in that pane!

Pay attention to the pwd and command history for each of the split-window panes in tmux!

	Q:
	how can i build a jenkins plugin from source, including all of its java dependencies also from source? Understand that I will have access to all source code but no active connection to the internet at all. No binary artifacts can be fetched to assist with the build process and all java jar files must be built from source only.

	A:
	Building a Jenkins plugin from source, along with its Java dependencies, without any internet connection and only using source code can be a complex and involved process. Here's a general guide on how you might approach this:

	1. Set Up Your Environment:

	- Install Java and Maven: Ensure you have Java JDK and Maven installed on your machine. Make sure you're using compatible versions with the Jenkins source code.

	#!/usr/bin/env perl

	# $ perl aes.pl decrypt $(perl aes.pl encrypt 123 qaz) # 123 is the key and qaz is the plaintext
	# qaz # qaz is the plaintext from the 123 ciphertext encryption

	# $ key=123 ciphertext=08eaad9aec6b6ccba1067aa4de838dd3d5c6423024d5eb087a4e70cd32b9caba
	# $ perl aes.pl decrypt $key $ciphertext
	# qaz
	# $ perl aes.pl decrypt 40bd001563085fc35165329ea1ff5c5ecbdbbeef40bd001563085fc35165329e $ciphertext
	# qaz # 40b...29e is the actual key derived from 123 and used in the enc/dec

	#!/bin/bash

	# This allows modifying a library with, e.g., patchelf and updating the FIPS-required .libXXX.hmac
	# to ensure that the library can be loaded on a FIPS-enabled system.

	# $ extract-hmackey libcrypto.so.1.1 '^[A-Za-z0-9 ]+$' '.\{16,64\}'
	# orboDeJITITejsirpADONivirpUkvarP
	# success
	# $ extract-hmackey libcrypto.so.1.1 '^a$' '.\{16,64\}'
	# fail
