In Gnome from nautilus to shell

Nautilus Scripts

Nautilus is the official file manager for the GNOME desktop. It has ability to run add-on scripts written in any scripting language (or binary file) without a problem. All add-on scripts must be created and stored at ~/.gnome2/nautilus-scripts ($HOME/.gnome2/nautilus-scripts) location.

Create Open Terminal Here (Open Shell Prompt Here) Shell script

Create file as follows using gedit text editor:
$ gedit "$HOME/.gnome2/nautilus-scripts/Open Terminal Here"
Append shell script code:

#!/bin/bash
# From Chris Picton
# Replaces a Script by Martin Enlund
# Modified to work with spaces in path by Christophe Combelles
 
# This script either opens in the current directory,
# or in the selected directory
 
base="`echo $NAUTILUS_SCRIPT_CURRENT_URI | cut -d'/' -f3- | sed 's/%20/ /g'`"
if [ -z "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS" ]; then
     dir="$base"
else
     while [ ! -z "$1" -a ! -d "$base/$1" ]; do shift; done
     dir="$base/$1"
fi
 
gnome-terminal --working-directory="$dir"

NAUTILUS_SCRIPT_CURRENT_URI variable gives current location for directory. NAUTILUS_SCRIPT_SELECTED_FILE_PATHS sets a newline-delimited paths for selected files.

Save and close the file. Now, setup permissions, enter::
$ chmod +x "$HOME/.gnome2/nautilus-scripts/Open Terminal Here"
And you are done. Open nautilus file manager, select directory > Right Click > Scripts > Open Terminal Here:
