       incrontab - table manipulator for inotify cron (incron)

       incrontab  is a table manipulator for the inotify cron (incron) system.
       It creates, removes, modifies and lists user tables (incrontab(5)).

       Each user (including even system users without home directories) has an
       incron  table  which  can’t  be  manipulated  directly  (only  root can
       effectively change these tables and is NOT recommended to do so).

       All informational messages of this program are printed to the  standard
       error output (stderr).

       If  /etc/incron.allow  exists  only  users  listed here may use incron.
       Otherwise if /etc/incron.deny exists only users NOT listed here may use
       incron.  If  none  of  these  files  exists  everyone is allowed to use
       incron. (Important note: This behavior is insecure and will be probably
       changed  to be compatible with the style used by ISC Cron.) Location of
       these files can be changed in the configuration.

       The first form of this command imports a file, validates it and  stores
       to the table. "-" can be used for loading from the standard input.

       -u  (or  --user)  option overrides the current (real) user to the given
       one. This option is intended for manipulation with system users’ tables
       (such  as  apache,  postfix,  daemon  etc.). It can be used only if the
       current user has root’s effective rights.

       -l (or --list) option causes  the  current  table  is  printed  to  the
       standard output.

       -r   (or  --remove)  option  causes  the  current  table  (if  any)  is
       permanently remove  without  any  warning  or  confirmation.  Use  with

       -e  (or  --edit) option causes executing an editor for editing the user
       table (see below for the information about editor selection).  You  can
       edit  your  incron  table  now.  If  the table is changed it stores the
       modified version.

       -t (or --types)  option  causes  the  list  of  supported  event  types
       (delimited  by  commas) is printed to the standard output. This feature
       is intended for front-end applications to find out  which  event  types
       was compiled in.

       -d   (or  --reload)  option  causes  reloading  the  current  table  by
       incrond(8). It is done through "touching" the table  (writing  into  it
       without  modifying  it).  This  feature  is  intended e.g. for creating
       watches on newly created files (with already  existing  rules)  or  for
       rearming IN_ONESHOT watches.

       -f  <FILE>  (or  --config=<FILE>) option specifies another location for
       the configuration file (/etc/incron.conf  is  used  by  default).  This
       feature requires root privileges.

       There  is a few complex algorithm how to determine which editor will be
       user for editing. If any of the following rule succeeds the appropriate
       editor is used:

       1. EDITOR environment variable

       2. VISUAL environment variable

       3. configuration value

       4. etc/alternatives/editor

       5. hard-wired editor (vim by default)

       It’s  not  recommended  to  use  graphical editors (such as gVim, KEdit
       etc.) due to possible problems with connecting to the X server.
