copying files from directory listed in a text file

[parijat24]

Hi ,

Actually I have just to copy some specific files from a directory. As there are 5000 files and I have to copy only 300. so I just want to make program which read the name of the file given in text file and then copies those file from the directory to some other directory . for ex

Directory parijat : a1.mol2 a2.mol2 ................................a5000.mol2

I want to copy a3.mol2, a890.mol2,a675.mol2,a4500.mol2 etc

so I have given alist containing file name

a3.mol2
a890.mol2
...
.
.
-
a4500.mol2

I am using bash but ...but it wont work out

cat file | while read line ; grep $line directory

This is Python forum and it is easy to do in Python, but in Linux or other unix style system you can use backquotes.

So to copy listed files from file 'file' to directory 'directory' you could do:

cp `cat file` directory

import shutil, os 
srcfolder = "/source/folder/here"
destinationfolder = "/destination/folder/here"
f = open("listed.txt")
for filename in f:
    shutil.copy(os.path.join(cwd, filename), destinationfolder)

This should do it?
