       incrond - inotify cron (incron) daemon


       incrond [ -f file ] [ -n | -k ]


       The  inotify  cron  daemon  (incrond)  is  a  daemon  which monitors filesystem events and
       executes commands defined in system and user tables. It's  use  is  generally  similar  to

       incrond  can  be  started  from  /etc/rc,  /etc/rc.local  and  so on. It daemonizes itself
       (returns immediately) and doesn't need to be started with & and through nohup(1).  It  can
       be run on foreground too.

       incrond  uses  two categories of tables incrontab(5). System tables are usually located in
       /etc/incron.d and are maintained outside of incron (e.g. by various  applications).  These
       tables  work  on  root  rights  level  and  thus  any file may be watched and commands are
       executed with root privileges.

       User tables are located in /var/spool/incron by default  and  have  names  based  on  user
       accounts. These tables use users' access rights, thus only files which the user may access
       are watched. Commands are executed with users' privileges.

       If a table (incrontab) is changed  incrond  reacts  immediately  and  reloads  the  table.
       Currently running child processes (commands) are not affected.

       There are two files determining whether an user is allowed to use incron. These files have
       very simple syntax - one user name per line. If /etc/incron.allow exists the user must  be
       noted  there  to  be  allowed to use incron. Otherwise if /etc/incron.deny exists the user
       must not be noted there to use incron. If none of these files exists  there  is  no  other
       restriction  whether anybody may use incron. Location of these files can be changed in the

       The daemon itself is currently not protected against looping. If a command executed due to
       an  event causes the same event it leads to an infinite loop unless a flag mask containing
       loopable=true is specified. Please beware of this and do  not  allow  permission  for  use
       incron to unreliable users.

       -n  (or  --foreground)  option causes running on foreground. This is useful especially for
       testing, debugging and optimization.

       -k (or --kill) option terminates a running instance of incrond.

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

       Environment  variables:  For  system  tables, the default (the same as for incrond itself)
       environment variable set is used. The same applies to  root's  table.  For  non-root  user
       tables,  the  whole environment is cleared and then only these variables are set: LOGNAME,
       USER, USERNAME, SHELL, HOME and PATH. The variables (except PATH)  take  values  from  the
       user     database     (e.g.    /etc/passwd).    The    PATH    variable    is    set    to


       incrontab(1), incrontab(5), incron.conf(5)


       incrond is currently not resistant against looping.
