# Python os.lchflags() Method

## Description:

This method sets the flags of path to the numeric flags. This method does not follow symbolic links unlike chflags() method.

Here flags may take a combination (bitwise OR) of the following values (as defined in the stat module):

- UF_NODUMP: Do not dump the file.

- UF_IMMUTABLE: The file may not be changed.

- UF_APPEND: The file may only be appended to.

- UF_NOUNLINK: The file may not be renamed or deleted.

- UF_OPAQUE: The directory is opaque when viewed through a union stack.

- SF_ARCHIVED: The file may be archived.

- SF_IMMUTABLE: The file may not be changed.

- SF_APPEND: The file may only be appended to.

- SF_NOUNLINK: The file may not be renamed or deleted.

- SF_SNAPSHOT: The file is a snapshot file.

NOTE: This method has been introduced in Python 2.6

## Syntax:

    os.lchflags(path, flags)

## Parameters:

Here is the detail of parameters:

- path: This is the file path for which flags to be set.

- flags: This could be a combination (bitwise OR) of the above defined flags values.

## Example:

    #!/usr/bin/python

    import os, sys

    # Open a file
    path = "/var/www/html/foo.txt"
    fd = os.open( path, os.O_RDWR|os.O_CREAT )

    # Close opened file
    os.close( fd )

    # Now change the file flag.
    ret = os.lchflags(path, os.UF_IMMUTABLE )

    print "Changed file flag successfully!!"

This would produce following result:

    Changed file flag successfully!!
