Search for a file using a wildcard
I want get a list of filenames with a search pattern with a wildcard. Like:
getFilenames.py c:\PathToFolder\*
getFilenames.py c:\PathToFolder\FileType*.txt
getFilenames.py c:\PathToFolder\FileTypeA.txt
How can I do this?
You can do it like this:
>>> import glob
>>> glob.glob('./[0-9].*')
['./1.gif', './2.txt']
>>> glob.glob('*.gif')
['1.gif', 'card.gif']
>>> glob.glob('?.gif')
['1.gif']
Note:
If the directory contains files starting with .
they won’t be matched by default. For example, consider a directory containing card.gif
and .card.gif
:
>>> import glob
>>> glob.glob('*.gif')
['card.gif']
>>> glob.glob('.c*')
['.card.gif']
This comes straight from here: http://docs.python.org/library/glob.html
glob
is useful if you are doing this in within python, however, your shell may not be passing in the *
(I'm not familiar with the windows shell).
For example, when I do the following:
import sys
print sys.argv
On my shell, I type:
$ python test.py *.jpg
I get this:
['test.py', 'test.jpg', 'wasp.jpg']
Notice that argv
does not contain "*.jpg"
The important lesson here is that most shells will expand the asterisk at the shell, before it is passed to your application.
In this case, to get the list of files, I would just do sys.argv[1:]
. Alternatively, you could escape the *
, so that python sees the literal *
. Then, you can use the glob
module.
$ getFileNames.py "*.jpg"
or
$ getFileNames.py \*.jpg
from glob import glob
import sys
files = glob(sys.argv[1])
