README

Linux configs by mikldt

This gist contains a couple of configs that I use. They're a combination of default config files, things I've found online, and my own work. They're mostly set up for my own use, but should be generic enough that you can adapt them as needed.

Feel free to download, use, modify, redistribute. If you redistribute any of my contributions to these files, attribution would be nice.

Included are a .bashrc and .screenrc. The .bashrc uses a .bash_prompt config file where a fance prompt is set up. There is also install.sh which creates links to all these files from the repository so you can pull updates.

Quick install:
cd ~; git clone git://gist.github.com/427834.git conf-gist; conf-gist/install.sh

install.sh

#!/bin/bash
# install.sh: Create symlinks so that user will use the 
# configurations specified in this repository
# ( http://gist.github.com/427834 )

LSOF=$(lsof -p $$ | grep -E "/"$(basename $0)"$")
MY_PATH=$(echo $LSOF | sed -r s/'^([^\/]+)\/'/'\/'/1 2>/dev/null)
CONFIG_DIR=$(dirname $MY_PATH)

cd $HOME

# Save old configs for posterity
if [ -f .bashrc ]; then
  mv .bashrc .bashrc.old
  echo ".bashrc moved to .bashrc.old"
fi

if [ -f .bash_prompt ]; then
  mv .bash_prompt .bash_prompt.old
  echo ".bash_prompt moved to .bash_prompt.old"
fi

if [ -f .screenrc ]; then
  mv .screenrc .screenrc.old
  echo ".screenrc moved to .screenrc.old"
fi

# Link in configs from this directory

`ln -s $CONFIG_DIR/.bash_prompt .bash_prompt`
