Help please with code to find and move files.
Hello,
I am new to python and wanted to write something for myself where
after inputing two words it would search entire drive and when finding
both names in files name would either copy or move thoe files to a
specified directory.
But couple of attempts did not work as desired this is one of them.
Could someone help fix it or maybe give a better example.
Thank you very much.
import os, os.path, shutil
path = r"c:\\"
dest_file = 'C:\\files'
name_search = raw_input('Please enter name searchs : ').split()
dup = []
for root, dirs, files in os.walk(path):
for name in files:
file_name = os.path.join(root, name)
if (name_search[0] in file_name) and (name_search[1]
in file_name):
#if os.path.join(root, name) in dest_file:
if file_name in dup:
break
else:
print "copied %s to %s" % (name,
dest_file)
shutil.copy(os.path.join(root, name),
dest_file)
dup.append(file_name)

John,
What I was trying to do is find files that are scattered all over my
hard drive that contain similar two words in them like bar and foo
and move them to one desired location removing from where they were
originally. The did not work as desired were attempts when it would
attempt to read and write to the same location.so i would get an error
saying that source and destination were the same.

I am sorry if I was not clear in what I was trying to achieve. All I
wanted was simple way to achieve what windows does when you use search
for Files or Folders, and all the files that mach two words like foo
and bar in the file name to be moved or copied to a specified folder,
duplicates should not be copied just skipped.

Extract value from a attribute in a string
Hello, I am looking for some help in reading a large text tile and extracting a value from an attribute? so I would need to find name=foo and extract just the value foo which can be at any location in the string. The attribute name will be in almost each line. Thank you for any suggestions. -- http://mail.python.org/mailman/listinfo/python-list
