Python os.fchown() Method The method fchown() changes the owner
and group id of the file given by fd to the numeric uid and gid.
To leave one of the ids unchanged, set it to -1. Note:This
method is available Python 2.6 onwards. Following is the syntax
for fchown() method os.fchown(fd, uid, gid); fd -- This is the
file descriptor for which owner id and group id need to be
setup. uid -- This is Owner ID to be set for the file. gid --
This is Group ID to be set for the file. This method does not
return any value. The following example shows the usage of
fchown() method. #!/usr/bin/python import os, sys, stat # Now
open a file "/tmp/foo.txt" fd = os.open( "/tmp", os.O_RDONLY ) #
Set the user Id to 100 for this file. os.fchown( fd, 100, -1) #
Set the group Id to 50 for this file. os.fchown( fd, -1, 50)
print "Changed ownership successfully!!" # Close opened file.
os.close( fd ) Let us compile and run the above program, this
will produce the following result: Changed ownership
successfully!!
