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 .
