+Skip default ignore statements. By default, watchexec ignores common temporary files for you, for example `*.swp`, `*.pyc`, and `.DS_Store`.

 ## ENVIRONMENT

-Processes started by watchexec have the `$WATCHEXEC_UPDATED_PATH` environment variable set to the path of the first modification observed. In addition, the `$WATCHEXEC_COMMON_PATH` environment variable is set to the common path of all observed modifications.
+Processes started by watchexec have environment variables set describing the modification(s) observed. Which variable is set depends on how many modifications were observed and/or what type they were.

+* `$WATCHEXEC_CREATED_PATH`, the path of the file that was created
+* `$WATCHEXEC_REMOVED_PATH`, the path of the file that was removed
