A ubiquitous shell. The default for almost all Linux distributions.

Random notes on this software.

Note that you will find a lot of example and working code on GitHub:

• /dead/bash
• /dead/bash-windows
• /live/bash

• /live/wfl

  • Specific for Windows Subsystem for Linux

• sh

  • sh code usually works under Bash.

• 2018-10-10 - I kept using Babun for some time, but I switched to Windows Subsystem for Linux and VirtualBox.
• 2016-03-28 - 4.2.53(2) on Slackware 14.1 i486
• 2016-03-26 - 4.3.11(1) on Lubuntu 14.04.4 LTS
• 2016-01-30 - 4.3.42(5) on Git on Windows 2.7.4 64-bit

• 2016-01-29 - 3.1.20(4)-release on Git on Windows Git-1.9.5-preview20141217

  • (earlier than this)
  • This was so damned old at the time that I had to jump through hoops to do scripting under this restriction.

• 2009-04-21 - 3.1.17 on (distribution not recorded)

  • It's the standard, but I bloody well hate how it works. It's so clumsy and GNU.

• Bash has come with every distribution I have ever used.

Configuration ∞

• $HOME/.inputrc
• $HOME/.bashrc is the best way.

• $HOME/.bash_profile only works for the raw TTY console, but not in X (a terminal).
