thanks for the input guys, I've tried the suggestions but can't get it to work. I have a file named test.htm in my directory, and when I run the following command: rename -vn 's/(.*)\.htm$/model.html/' *.htm from the shell in that directory I get the following output: test.htm renamed as model.html now my python script is called test.py, is located in the same directory, and is called from the shell with 'python test.py' the contents of test.py: import subprocess p = subprocess.Popen(['rename','-vn','s/(.*)\.htm$/ model.html/','*.htm'],stdout=subprocess.PIPE,stderr=subprocess.PIPE) print p.communicate()[0] i change to print p.communicate()[1] in case the output is blank the first time this is the output: *.htm renamed as model.html when I add shell=True to the subprocess command, I get the following output: Usage: rename [-v] [-n] [-f] perlexpr [filenames] am i doing something wrong? -- http://mail.python.org/mailman/listinfo/python-list
