+The `publishDir` directives for one task can be spread over the workflow file and many config files. Each `publishDir` has to be disabled individually. To skip all publishDir directives at once for a process, set the `skipPublishDir` directive for the according process.

+```groovy
+process foo {
+    publishDir '/data/chunks1', mode: 'copy', overwrite: false
+    publishDir '/data/chunks2', mode: 'copy', overwrite: false
+    publishDir '/data/chunks3', mode: 'copy', overwrite: false
+    skipPublishDir true
