incrontab - table manipulator for inotify cron (incron)
incrontab [-u user] [-f config] file
incrontab [-u user] [-f config] [-l | -r | -e | -t | -d]
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
-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
-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
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.
