Zaxon,
Look at this example to see if it makes sense.
2>&1 means "send standard error (file descriptor 2) to the same place standard output (file descriptor 1) is going."
n>&m is an operator
in this case
5>&1 is an operator
5 is file descriptor 5
1 is file descriptor 1
Hope it helps!

inotify_rm_watch
INOTIFY_RM_WATCH(2) Linux Programmer's Manual INOTIFY_RM_WATCH(2)
NAME
inotify_rm_watch - remove an existing watch from an inotify instance
SYNOPSIS
#include <sys/inotify.h>
int inotify_rm_watch(int fd, int wd);
DESCRIPTION
inotify_rm_watch() removes the watch associated with the watch descriptor wd from the inotify instance associated with the file descriptor
fd.
Removing a watch causes an IN_IGNORED event to be generated for this watch descriptor. (See inotify(7).)
RETURN VALUE
On success, inotify_rm_watch() returns zero, or -1 if an error occurred (in which case, errno is set appropriately).
ERRORS
EBADF fd is not a valid file descriptor.
EINVAL The watch descriptor wd is not valid; or fd is not an inotify file descriptor.
VERSIONS
Inotify was merged into the 2.6.13 Linux kernel.
CONFORMING TO
This system call is Linux-specific.
