NAME
       file - event signalling that a file has changed

SYNOPSIS
       file FILE=PATH EVENT=TYPE [MATCH=PATH]

DESCRIPTION
       The file event is generated by the upstart-file-bridge(8) daemon when a
       file whose details match the file event condition and environment spec‐
       ified in a job's start on or stop on stanza is modified.

       The FILE and EVENT environment variables will be set to the same values
       as specified by the job. Note that if the job  did  not	specify	 EVENT
       this  will still be set to one of create, modify or delete depending on
       what type of file event caused the event to be emitted.

       If the job specified a glob pattern in the file part of the FILE	 envi‐
       ronment variable, the event will contain the MATCH environment variable
       which will be set to the full path of the file that matched the pattern
       in FILE.

NOTES
       ·   When	 specifying  a path that contains spaces, ensure that the path
	   is quoted.

       ·   FILE values specified by jobs are not canonicalised; this cannot be
	   done reliably as they may not exist so cannot be fully resolved.

       ·   If  you  wish  to match on MATCH, ensure that FILE does not contain
	   multiple consecutive runs of slashes since otherwise your job  will
	   find it difficult to perform such a match.

EXAMPLES
       start on file FILE=/run/app.pid EVENT=create
	   Event emitted when file is created.

       start on file FILE=/run/app.pid
	   Event emitted when file is created, modified or deleted.

       start on file FILE=/var/log/
	   Event  emitted  when files within a directory are created, modified
	   or deleted.

       start on file FILE=/var/crash/*.crash EVENT=create
	   Event emitted when files that match a glob pattern are  created  in
	   the indicated directory.

       start on file FILE="/this/path/contains whitespace.txt"
	   Specify a file that contains a space character.
