Python3 os.mknod() Method
Python3 OS File/Directory Methods
Overview
The os.mknod()
method is used to create a filesystem node (file, special file, or named pipe) with a specified filename.
Syntax
The syntax for the mknod() method is as follows:
os.mknod(filename[, mode=0600[, device=0]])
Parameters
-
filename -- The filesystem node to be created.
-
mode -- The mode specifies the permissions for creating or using the node, combined (or bitwise) with stat.S_IFREG
, stat.S_IFCHR
, stat.S_IFBLK
, and stat.S_IFIFO
(these constants are in the stat
module). For stat.S_IFCHR
and stat.S_IFBLK
, the device defines the newly created device special file (possibly using os.makedev()
), and others will be ignored.
-
device -- Optional, specifies the device for the file creation.
Return Value
This method does not return a value.
Example
The following example demonstrates the use of the mknod()
method:
#!/usr/bin/python3
import os
import stat
filename = '/tmp/tmpfile'
mode = 0600|stat.S_IRUSR
# Specify different modes for the filesystem node
os.mknod(filename, mode)
Executing the above program will produce the following output:
-rw-------. 1 root root 0 Apr 30 02:38 tmpfile
