It's not obvious what the functions you call do. I'd be clearer if you
posted all the code. I will assume `lilynameGen(name)` returns a new
name for a file named `name`. So a script to rename one file might
be::
#!/usr/bin/env python
def lilynameGen(name):
... your rename logic here ...
return newname
import sys, shutil
name = sys.argv[1] # first command-line arg (argv[0] is script name)
shutil.move(name, lilynameGen(name))
If you want to work on a list of files, just use a for loop at the end::
for name in sys.argv[1:]: # all command-line args
shutil.move(name, lilynameGen(name))
This script can be run with a list of names, e.g.::
$ script.py a.ly b.ly
If you use glob patterns in the command line::
$ script.py *.ly
the shell expands them to a list of arguments - the script never knows
you didn't type them one by one. If you don't get names from the
command line and want to expand glob patterns inside python code, you
can use the glob module::
import glob
for name in glob.glob('*.ly'):
shutil.move(name, lilynameGen(name))
Hope that helped. If you have more questions, please post the entire
code you wrote and/or state the precise behavior you need.
And post python question to python@linux.org.il to get quicker help.
