Sometimes.  In this case, it was quite a reasonable question (I hope
you don't get offended by ``RTFM''; IMO, you'd learn a lot more if I
told you where to find the answer rather than provide it for you).
That said, there are a few places you could look:

  1) The ``SEE ALSO'' section in related manual pages.  ipcs(1) lists
     ipcrm(1) in its ``SEE ALSO'' section.

  2) apropos(1).  This is convenient if you know what the description
     of the command might contain, but not what the actual command is.  E.g.,
     `apropos ipc` yields:

	ftok(3) - create IPC identifier from path name
	ipcrm(1)                 - remove the specified message queues, semaphore sets, and shared segments
	ipcs(1)                  - report System V interprocess communication facilitiesstatus
	mbuf(9)                  - memory management in the kernel IPC subsystem
	perlipc(1)               - Perl interprocess communication (signals, fifos, pipes, safe subprocesses, sockets, and semaphores)
	IPC::Msg(3), s-1IPC:s0:Msg(3) - SysV Msg s-1IPCs0 object class
	IPC::Open2(3), s-1IPC:s0:Open2(3), open2(3) - open a process for both reading and writing
	IPC::Open3(3), s-1IPC:s0:Open3(3), open3(3) - open a process for reading, writing, and error handling
	IPC::Semaphore(3), s-1IPC:s0:Semaphore(3) - SysV Semaphore s-1IPCs0 object class
	IPC::SysV(3), s-1IPC:s0:SysV(3) - SysV s-1IPCs0 constants

     As you can see, not everything is relevant, but unless you get
     pages after pages of matches, it can't hurt to look through it just in
     case you find what you need.  In this case, ipcrm(1) jumps out as
     a potential answer.
