"find" equivalent for strings?

[Mike Miller]

Simple example input file:

bob
joe
sally
bob
bob

reading in the data:

x=textread("file.txt","%s");

x =

{
  [1,1] = bob
  [1,2] = joe
  [1,3] = sally
  [1,4] = bob
  [1,5] = bob
}

Now I want to determine which elements of x consist of "bob" (so I want 
the vector [1,4,5] returned), but I'd rather not use a loop.  Is there any 
way to do this without doing strcmp on every element of the cell?

Mike
