Following bash script can be used to run all at once. It is recommended to create file, e.g. buildMesh:

#!/bin/bash
# --------------------------------------------------------------------------- #
#   ==   ===  ==                                                              #
#  ||   ||=  || ))  support s. r. o. 2014, www.cfdsupport.com                 #
#   ==        ==                                                              #
# --------------------------------------------------------------------------- #

if [[ $(echo $WM_PROJECT_VERSION |  cut -c1-3) != "2.3" ]]; then
    echo "You need OpenFOAM 2.3 to build the mesh."
    exit 0
