Is there a way to use the tarfile module to recursively compress the
contents of a directory and maintain the directory structure in the
tar archive?
Simply doing os.system('tar -czvf ' + fileName +'.tar.gz ' +
directory)
works great on linux, but I need this script to work on windows as
well :( 8 11143

GNU tar, and surely others, have been ported to Windows. Check within
the DJGPP and Cygwin projects.

Starting from Python 2.3 there is a tarfile module in the stdlib http://docs.python.org/lib/module-tarfile.html

You can use os.walk (or os.path.walk for older versions of Python) to
recurse a directory tree. Here's a simple script to use tarfile and
os.walk:
import tarfile, sys, os
t = tarfile.TarFile (sys.argv[1], "w")
for f in sys.argv[2:]:
for dirpath, dirnames, filenames in os.walk(f):
for f in filenames:
f = os.path.join(di rpath, f)
print "Adding", f
t.add(f)
t.close()
Here's a sample session with it:
* Creating a simple directory structure
$ mkdir a
$ touch a/file.txt
$ mkdir a/subdir
$ touch a/subdir/subfile.txt
* Invoking the script
$ python ~/mktar.py test.tar a
Adding a/file.txt
Adding a/subdir/subfile .txt
* Checking on the results
$ tar tvf test.tar
-rw-rw-r-- jepler/jepler 0 2004-08-17 21:00:57 a/file.txt
-rw-rw-r-- jepler/jepler 0 2004-08-17 21:01:03 a/subdir/subfile.txt
I suspect that to get compressed output would involve use of gzip.open
and the 3-argument TarFile constructor, something like
import gzip
g = gzip.open(sys.a rgv[1], "w")
t = tarfile.TarFile (sys.argv[1], "w", g)
...
indeed, this seems to work for me.
$ python ~/mktargz.py test.tar.gz a
Adding a/file.txt
Adding a/subdir/subfile.txt
$ file test.tar.gz
test.tar.gz: gzip compressed data, was "test.tar", max compression

Far too complicated... tarfile.py is rather high-level:
import tarfile
tar = tarfile.open(fi lename, "w:gz")
tar.add(directo ry)
tar.close()
The add() method is recursive by default. More information and examples
here: http://docs.python.org/lib/module-tarfile.html

That doesn't maintain the directory structure. When you untar it all
the files are in the base directory (when I untar it on windows with
winzip).
I haven't tried jeff's suggestion yet, but I'll let ya'll know how
that goes.

Winzip is probably broken? It works for me using GNU tar on Linux.

There was a bug report relating to tarfile & WinZip: http://sourceforge.net/tracker/?grou...ail&aid=949052
Looks like it was closed today.

This works perfectly on linux, but it wasn't working for me on windows
yesterday. I'll try it again the next time I'm on windows. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

when creating a project with namespace like:

is it good practice to have the directory structure like that also:
c:\wrox\csharp\basics\overflowtext.cs
Also if it is then is there a way to make visual studio set it up for
me as i'm creating the cs files? or do i have to first create the
directory structures and then as i save files save them in the correct
places depending on the namespace i create.
