Python method chflags() sets the flags of path to the numeric flags. The flags may take a combination (bitwise OR) of the various values described below.
Note − This method is available Python version 2.6 onwards. Most of the flags can be changed by super-user only.
Following is the syntax for chflags() method −
path − This is complete path of the directory to be changed to a new location.
flags − The flags specified are formed by OR'ing the following values −
so.UF_NODUMP − Do not dump the file.
so.UF_IMMUTABLE − The file may not be changed.
so.UF_APPEND − The file may only be appended to.
so.UF_NOUNLINK − The file may not be renamed or deleted.
so.UF_OPAQUE − The directory is opaque when viewed through a union stack.
so.SF_ARCHIVED − The file may be archived.
so.SF_IMMUTABLE − The file may not be changed.
so.SF_APPEND − The file may only be appended to.
so.SF_NOUNLINK − The file may not be renamed or deleted.
so.SF_SNAPSHOT − The file is a snapshot file.
This method does not return any value.
The following example shows the usage of chflags() method.
#!/usr/bin/python import os import stat path = "/tmp/foo.txt" # Set a flag so that file may not be renamed or deleted. flags = os.SF_NOUNLINK retval = os.chflags( path, flags) print "Return Value: %s" % retval
When we run above program, it produces following result −
Return Value : None
