Bash statusline

statusline.sh

# Color codes look like this: \033[1;34m
#
# When used in a prompt, color codes and other special sequences have to be
# escaped so they are not counted in the width of the bash prompt. If the width
# is not calculated correctly backspace, up arrow, etc. will not work correctly.
#
# In the bash prompt itself (PS1) you should use the \[ \] an escape sequence.
# This indicates to bash that these characters are not part of the prompt.
#
# If you're using color codes in a bash function that is used in your prompt,
# you instead need to use \001 and \002 to indicate the start and end of special
# codes, respectively.

# Git Prompt

# Note you can get these via git clone https://github.com/git/git ~/code/git

Last part i was doing git clone, so I ended with this:

for file in git-completion.bash git-prompt.sh; do
   [ -f ${code}/${file} ] || curl -sSL https://raw.githubusercontent.com/git/git/master/contrib/completion/${file} -o ${code}/${file}
done

source ${code}/git-completion.bash
source ${code}/git-prompt.sh

Ah great idea!
