Batch rename files by providing a string to be `eval`ed, using variable `x` as
|
|
the current filename.
|
|
Yes I know this is weird, but for certain tasks it's just too quick and easy to pass up.
|
|
|
|
For example:
|
|
|
|
Prefix all the files:
|
|
brename.py "'Test_' + x"
|
|
|
|
Keep the first word and extension:
|
|
brename.py "(x.split(' ')[0] + '.' + x.split('.')[-1]) if ' ' in x else x"
