Python os.fchdir() Method with example



Hello dear readers! Welcome back to another section of my tutorial on Python. In this tutorial guide, we are going to be studying about the Os fchdir() method.

os fchdir() changes the current working directory into the directory which is represented by the file descriptor fd. The descriptor must refer to an opened directory, not an open file.

Syntax

The following below is the syntax for Python Os fchdir() method -

os.fchdir( fd );


Parameter Details

  • fd - This is the Directory descriptor.

Return Value

It does not return any value.

Example

The following below is a simple example -

#!/usr/bin/python

import os, sys

# First go to the "/var/www/html" directory
os.chdir("/var/www/html" )

# Print current working directory
print "Current working dir : %s" % os.getcwd()

# Now open a directory "/tmp"
fd = os.open( "/tmp", os.O_RDONLY )

# Use os.fchdir() method to change the dir
os.fchdir(fd)

# Print current working directory
print "Current working dir : %s" % os.getcwd()

# Close opened directory.
os.close( fd )

Output
When the above code is executed, it will produce the following result -

Current working dir : /var/www/html
Current working dir : /tmp
