DESCRIPTION¶
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 caution!
-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.
