+The datalad run command can record the impact a script or command has on a Dataset.
|
|
|
+In its simplest form, datalad run only takes a commit message and the command that
|
|
|
+should be executed.
|
|
|
+
|
|
|
+Any datalad run command can be re-executed by using its commit shasum as an argument
|
|
|
+in datalad rerun CHECKSUM. DataLad will take information from the run record of the original
|
|
|
+commit, and re-execute it. If no changes happen with a rerun, the command will not be written
|
|
|
+to history. Note: you can also rerun a datalad rerun command!
