Files and Directories
These functions operate on files and directories.
-
access(path,mode) Checks read/write/execute permissions for this process or file
path. Returns 1 if access is granted, if not. See the Unix manual for the semantics. Availability: Unix.-
chmod(path,mode) Changes the mode of
pathto the numericmode. Availability: Unix, Windows.-
chown(path,uid,gid) Changes the owner and group ID of
pathto the numericuidandgid. Availability: Unix.-
link(src,dst) Creates a hard link pointing to
srcnameddst. Availability: Unix.-
listdir(path) Returns a list containing the names of the entries in the directory. The list is in arbitrary order. It doesn’t include the special entries "
." and ".." even if they are present in the directory. Availability: Macintosh, Unix, Windows.-
lstat(path) Like
stat(), but doesn’t follow symbolic links. Availability: Unix.-
mkfifo(path[,mode]) Creates a FIFO (a named pipe) named
pathwith numeric modemode. The default mode is 0666 (octal). The currentumaskvalue is first masked out from the mode. Availability: Unix.FIFOs are pipes that can be accessed like regular files. FIFOs exist until they are deleted (for example with
os.unlink()). Generally, FIFOs are used as rendezvous between client and server type processes: the server opens the FIFO for reading, and the client opens it for writing. Note thatmkfifo()doesn’t open the FIFO, it just creates the rendezvous point.-
mkdir(path[,mode]) Creates a directory named
pathwith numeric ...
