Script for starting a gollum wiki (from anywhere) in the background when developing with RVM.

gollum.sh

#!/bin/bash
# Load RVM into a shell session *as a function*
if [[ -s "$HOME/.rvm/scripts/rvm" ]] ; then

# First try to load from a user install
  source "$HOME/.rvm/scripts/rvm"

elif [[ -s "/usr/local/rvm/scripts/rvm" ]] ; then

# Then try to load from a root install
  source "/usr/local/rvm/scripts/rvm"

else

  printf "ERROR: An RVM installation was not found.\n"

fi

# Open project folder
cd "$HOME"/wiki/;
# In case loading RVM isn't enough (c.f. in a project specific gemset) uncomment the next line
# rvm use 1.9.3@wiki

# Start gollum on port 61001 and run it in the background
screen -dmS wiki "$HOME"/.rvm/gems/ruby-1.9.3-p448@wiki/bin/gollum --port 61001

Starting Gollum Shell Script

Script for starting a gollum wiki (from anywhere) in the background when developing with RVM.

The first part of the script checks if the RVM-Ruby environment is used instead of your login shell (see https://rvm.io/workflow/scripting/).

The second part is starting the wiki in the background with screen.

About screen

• for checking all screens open in the background: screen -ls
• for reconnecting to the wiki: screen -r wiki
  • leaving the wiki running and returning to the shell: ⌃A + D
  • closing the background screen: ⌃C

Notes

I tried to set the path to the script in a variable like in this excellent article Personal Wiki using GitHub and Gollum on OS X.
But the example code DIR="$( cd -P "$( dirname "${BASH_SOURCE[0]}" )" && pwd )" didn't work for me. The above solution is running smoothly now with my setup.
