Create a .screen directory in your home directory.

mkdir "$HOME/.screen"

Add the following to your .bashrc or .bash_profile.

sp() {
  if [[ -f "$HOME/.screen/$1" ]]; then
    screen -c "$HOME/.screen/$1"
  else
    echo "Unknown screen profile '$1'."
  fi  
}

Create a file in the ~/.screen directory with whatever profile name you would like to use (below is a sample profile named tyrion).

You should copy the first line into each profile as it loads your default GNU Screen settings.

source "$HOME/.screenrc"

chdir "$HOME/src/tyrion/src"
screen -t code  0

chdir "$HOME/src/tyrion"
screen -t build  1

chdir "$HOME/src/tyrion/tests"
screen -t tests  2

chdir "$HOME/src/tyrion"

Reload your shell and test your profile (replace tyrion with whatever name you picked).

[silas@example ~]$ sp tyrion
