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 specified 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 environment 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.
