Regex Match "words" That Contain Periods perl <p>I am going through a TCPDUMP file (in .txt format) and trying to pull out any line that contains the use of the "word" V.I.D.C.A.M. It is embedded between a bunch of periods and includes periods which is really screwing me up, here is an example: </p> <blockquote> <p>E..)..@.@.8Q...obr.f...$[......TP..P&lt;........SMBs......................................NTLMSSP.........0.........`b.m..........L.L.&lt;...V.I.D.C.A.M.....V.I.D.C.A.M.....V.I.D.C.A.M.....V.I.D.C.A.M.....V.I.D.C.A.M..............W.i.n.d.o.w.s. .5...1...W.i.n.d.o.w.s. .2.0.0.0. .L.A.N. .M.a.n.a.g.e.r..</p> </blockquote> <p>How do you handle something like that? </p>
