"Cloning" file attributes and permissions

[Kevin Kelley]

This is what I (just now) put together as an example:

from os import stat,mknod,chown

def match_perms(org_fname,new_fname):
    # Get information on old file
    st = stat(org_fname)
    st_mode = st.st_mode
    st_uid = st.st_uid
    st_gid = st.st_gid

    # Create the new file
    mknod(new_fname,st_mode)

    # Matching permissions
    chown(new_fname,st_uid,st_gid)

if __name__ == "__main__":
    match_perms('old_filename','new_filename')
