bashrc

The one bashrc to rule them all

To clone:

GIT_SSH_COMMAND='ssh -i ~/.ssh/id_rsa_personal' git clone ...

Mac OS X:

Install Homebrew or MacPorts

brew install bash-completion
brew install zsh-completions
sudo port install bash-completion
sudo port install zsh-completions

Windows:

pacman -S git

Set MSYS=winsymlinks:nativestrict or CYGWIN=winsymlinks:nativestrict. This will change the behavior of ln to use mklink and create native Windows symlinks.

WARNING: You need to run install.sh as administrator, as users don't have the permission to create symlinks. (http://superuser.com/questions/124679/how-do-i-create-a-link-in-windows-7-home-premium-as-a-regular-user)

If the Windows user you are running msys under is not an administrator, run cmd.exe as administrator, then run msys2 shell and then do 'export $HOME=/home/' befor running the install.sh script

Also, the msys2 vim package comes without 'vi' alias, run cmd.ex as administrator and do in /usr/bin 'ln -s vi vim.exe'

To share Windows and MSys2 home directories, add the following line to /etc/fstab and relogin to Windows

C:/Users /home ntfs binary,noacl,auto 1 1

CentOS

yum install bash-completion -y

Automatic macOS keychain unlock over SSH

The SSH client sends SNAPPY_KEYCHAIN_PASSWORD only when connecting to snappy or snappy.ts. On a trusted Linux client, save the password in the local mode-600 file ~/.ssh/snappy-keychain-password:

~/src/bashrc/scripts/set-snappy-keychain-password

On the macOS SSH server, install the tracked sshd configuration once:

sudo install -m 644 ~/src/bashrc/sshd-keychain.conf /etc/ssh/sshd_config.d/100-bashrc-keychain.conf
sudo launchctl kickstart -k system/com.openssh.sshd

Interactive SSH clients without the saved password still get the normal keychain password prompt. Command-only SSH sessions unlock the keychain from the received password before running their command.

Known hacks

Windows shrc.cmd doesn't load the aliases file

• Symptom: Aliases added to the Unix-side aliases file don't automatically show up in cmd on Windows.
• Cause: shrc.cmd doesn't source aliases. It hardcodes a minimal set of doskey definitions inline (ls, cat, e, cld, cdx, cpl) and that's the whole list.
• Workaround: If you need an alias in cmd, duplicate it as a doskey line inside shrc.cmd.
• When it breaks again: Every time a new alias gets added to aliases and someone expects it to Just Work in cmd. It won't. Edit shrc.cmd manually, or finally bite the bullet and teach shrc.cmd to parse aliases (lol, no — screw that guy).
