i = 0


##  search substring to replace
pattern = "wp-content\\\\uploads\\\\"


##  replace with...
replacement = ""


## folder to look in for file pattern
base_path = "/home/jogi/Projects/elusive.github.io/assets/images/"


## loop through files found by pattern
for pathname in  glob.glob(base_path + "wp-content\\uploads\\*.*"):


    # PATHNAME
    print("pathname =", pathname) ## TEST OUTPUT


    ## BASENAME
    basename = os.path.basename(pathname)
    #print("basename =", basename) ## TEST OUTPUT


    ## CALCULATE NEW FILENAME WITH REGULAR EXPRESSIONS
    NewFilename = re.sub(pattern, replacement, pathname)
    print("new-file-name = ", NewFilename)  ## TEST OUTPUT


    ## Change the name
    os.rename(pathname, NewFilename)
    i = i + 1


print("Total files renamed: " + str(i))
