NAME

       dnotify - Execute a command when the contents of a directory change

SYNOPSIS

       dnotify [OPTION]... DIRECTORY... [-e COMMAND...]

DESCRIPTION

       This manual page document describes the dnotify command.

       The  dnotify program executes COMMAND every time the contents of any of
       the specified directories change. If a command is not specified,  `echo
       {}' is assumed.

       What   is   considered  a  change  is  determined  by  the  `--access',
       `--modify', `--create', `--delete', `--rename' and  `--attrib'  options
       (see  below).  These  options  may  be  combined.  If  none of them are
       specified, create and delete are assumed.

       The string `{}' in the command specification is replaced by the name of
       the directory that was updated.

OPTIONS

       This  program  follow  the  usual  GNU  command  line syntax, with long
       options starting with two dashes (`-').

       -A, --access
              Trigger the command when a file in one of  the  directories  was
              accessed (read).

       -M, --modify
              Trigger  the  command  when a file in one of the directories was
              modified (i.e. written or truncated).

       -C, --create
              Trigger the command when a file was created in a directory.

       -D, --delete
              Trigger the command when a file was removed from a directory.

       -R, --rename
              Trigger the command when a file in one of  the  directories  was
              renamed.

       -B, --attrib
              Trigger  the  command  when a file in one of the directories had
              its attributes changed (as a result of chmod or chown).

       -a, --all
              Trigger the command when any of the events above  occurs.   That
              is, this is a shorthand for '-AMCDRO'.

       -e, --execute=COMMAND...
              This  option  specifies  the  command  to execute. All arguments
              (including possible options) following this option  are  treated
              as arguments to the command.

              The  string `{}' in the command specification is replaced by the
              name of the directory that was updated (just like find(1)).

       -f, --file=FILE
              The option  specifies  a  file  containing  directory  names  to
              monitor,  as  if  they  had  been specified on the command line.
              There must be one directory name per line in the file.

              This option can be used multiple times.

       -p, --processes=COUNT
              This option specifies the maximum number of commands to  be  run
              at the same time. It is possible to allow an unlimited number of
              commands to be run at the same time by specifying COUNT as 0  or
              -1.

              The default value is 1.

       -q, --queue=DEPTH
              This option specifies the maximum number of commands to queue up
              while there  are  other  commands  already  executing.  This  is
              usually  used  in  conjunction  with  the --processes option. An
              unlimited depth of the queue can be achieved by specifying DEPTH
              as -1.

              The default value is -1.

       -t, --times=COUNT
              Exit  dnotify  once  the  command  has  been  run  (and finished
              running) COUNT times.

       -o, --once
              Exit dnotify when the specified command has been run once.  This
              is equivalent to `--times 1'.

       -r, --recursive
              Traverse    the    specified   directories   and   monitor   all
              subdirectories (at any depth) as well.

              dnotify  will  only  scan   directories   once   to   find   out
              subdirectories to monitor when recursive mode is enabled. If you
              want to monitor any subdirectory created, you will have to  stop
              and restart dnotify every time a create or delete event occurs.

       -b, --background
              Run  dnotify in the background - detach from terminal.  Prior to
              executing  any  commands,  dnotify  will  change   the   current
              directory  to  the  root directory (`/'). Relative path names of
              directories to monitor will be made  absolute  automaticly,  but
              make  sure  the command you specify does not rely on the current
              directory being unchanged.

       -s, --silent, --quiet
              Do not print warnings when the executed commands  exits  with  a
              non-zero return value.

       --help Show summary of options.

       --version
              Output version information and exit.

EXAMPLES

       Print  'change'  to the terminal every time a file (or part of file) in
       /etc is read.
            dnotify -A /etc -e echo change

       Execute the script 'informdelete' every time a  file  in  /var/mail  is
       created or deleted.
            dnotify -CD /var/mail -e informdelete
