#
# file .sh that rename the file name and string inside the files 
#
# simply choose the string to be replaced and launch ./run_rename.sh in command line
# place the .sh file outside the folder (and subfolders) that you want to modify
# you have to choose the path of the folder to modify
#
#
# step 1: put the run_rename.sh just outside the robotran project
# step 2: modify the run_rename file : type_path, old_name, new_name
# step 3: run the run_rename.sh in command line ( "./run_rename.sh" if it is put as a executable file).
# 
# BE ADVISED: 
# the .sh modifies files names and content ! 
#
# FOR UNIX ONLY 
# FOR GIT PROJECT ONLY
# 
# if you want to use for a non-git project, just suppress the "git" commands
