grep for exact string

[TSch]

Hi folks,

I have a list containing several server names.

Like this:

servio1
servio2
rzvio1
rzvio2
brzvio1
brzvio2

Now I'd like to search this list for the server "rzvio1"

If I use grep it gives me rzvio1 as well as brzvio1 ...

Is there any way to perform a grep for an exact string so that it will only return rzvio1 as search output?

Regards
Thomas

oops, found it !

grep -w

Also, if this is the first column in your file, I think the following should also work

grep ^rzvio1 filename
