Python os.fchdir() Method with example

Hello dear readers! Welcome back to another section of our 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.


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.


The following below is a simple example -


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

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

# Close opened directory.
os.close( fd )

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

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