If path is a directory, it is copied recursively. In this case, if path ends with "/", only inside contents of that directory are copied to destination. Otherwise, if it does not end with "/", the directory itself with all contents is copied. This behavior is similar to Rsync. required: false default: null aliases: [] content: version_added: "1.1" description: - When used instead of 'src', sets the contents of a file directly to the specified value. required: false default: null dest: description: - Remote absolute path where the file should be copied to. If src is a directory, this must be a directory too. required: true default: null backup: description: - Create a backup file including the timestamp information so you can get the original file back if you somehow clobbered it incorrectly. version_added: "0.7" required: false choices: [ "yes", "no" ] default: "no" force: description: - the default is C(yes), which will replace the remote file when contents are different than the source. If C(no), the file will only be transferred if the destination does not exist. version_added: "1.1" required: false choices: [ "yes", "no" ] default: "yes" aliases: [ "thirsty" ] validate: description: - The validation command to run before copying into place. The path to the file to validate is passed in via '%s' which must be present as in the visudo example below. required: false default: "" version_added: "1.2" others: description: - all arguments accepted by the M(file) module also work here required: false author: Michael DeHaan notes: - The "copy" module recursively copy facility does not scale to lots (>hundreds) of files. For alternative, see "Delegation" section of the Advanced Playbooks documentation.
