I have copied this question over here from unix.StackOverflow
When I use incrontab out of the box, I mean no changes, I get no result, as if the cmd was not executed.
my incron line is : /crrae IN_CREATE,IN_CLOSE_WRITE,IN_MOVED_TO /usr/bin/unix2dos $#
the log give information as if everything was ok but no actually
the strace generated is: incrontab_trace_0.txt

When I change my incron to:
/crrae IN_CREATE,IN_CLOSE_WRITE,IN_MOVED_TO /usr/bin/unix2dos /crrae/$#
or
/crrae IN_CREATE,IN_CLOSE_WRITE,IN_MOVED_TO /usr/bin/unix2dos $@/$#
the log give me this:
May 4 18:15:10 srvovs incrond[20859]: (root) CMD (/usr/bin/unix2dos /crrae/u2dtmpPbqoFd)
May 4 18:15:10 srvovs incrond[20859]: (root) CMD (/usr/bin/unix2dos /crrae/u2dtmpN2Odxf)
May 4 18:15:10 srvovs incrond[20859]: (root) CMD (/usr/bin/unix2dos /crrae/u2dtmpN2Odxf)
multiple times, the incron.conf has not been modified. Any ideas?
