To avoid a lot of 'or’s you could do something along the lines of:{x where “b”$(+/){x like y}[x;] each (“*foo*”;“*bar*”;“*baz*”)} read0:/path/to/file.txtOn May 12, 1:22?pm, pawan singh <pawan.sing...> wrote:&gt; something like... ?{x where (x like "*foo*")or(x like "*goo*")}read0&gt; :/q/log.txt>>>>>> On Wed, May 12, 2010 at 10:06 PM, Pravin <pravin198…> wrote:> > Hi all,>> > ?could you please help me in finding out how to match more than one> > strings in ?a file .
