import ""

Package utils contains common methods used in most packages in Statping. This package contains multiple function like: Logging, encryption, type conversions, setting utils.Directory as the current directory, running local CMD commands, and creating/deleting files/folder.

You can overwrite the utils.Directory global variable by including STATPING_DIR environment variable to be an absolute path.
