A script to raise a GVIM window if the file is already being edited

gvim.sh

if [[ "$1" == -f ]]; then
	file=$2
else

  # The file exists so let's see if we are already editing
  #
  # List its long-form process details
  #
	psline=( $(ps -C gvim -o pid= -o args= | grep "gvim.* $file" 2>/dev/null) )
  #
  # If it exists, the first token will be the pid
  #
	GVIMPID=${psline[0]}
	if [[ "$GVIMPID" ]]; then
		#
		# It's already active - raise it
		#
    
    #
    # Find the window ID
    #
		WINID=( $(wmctrl -lp | awk '{print $3 " " $1}' | grep "^$GVIMPID" | awk '{print $2}') )

    #
    # If only one window ID was found, then raise it and exit
    #

# In all other circumstances, execute real gvim
