12.4. Updating the Modification Time of a File: The Touch Factory

If you just need to update the recorded modification time for a file, use the Touch factory: 

Command(
    "file.out",
    "file.in",
    action=[
        Copy("$TARGET", "$SOURCE"),
        Touch("$TARGET"),
    ]
)

Which executes as: 

% scons -Q
Copy("file.out", "file.in")
Touch("file.out")
