Find string by regular expression

I need to make a regular expression to extract some strings.

The searching string could be like:

ANY_STRING(string1)this is
searching string1
ANY_STRING(string2)this is
searching string2

The match strings should be:

(string1)this is searching string1
(string2)this is searching string2

Any idea?

Thanks.

assuming your strings to search are always between the brackets and assuming you are on *nix

$ awk '{match($0,/\(/);printf "%s ", substr($0,RSTART)} !/\(/{print ""}' file
(string1)this is searching string1
(string2)this is searching string2

Otherwise, you should provide more concrete data.

Have a look at interactive evaluators for regular expressions e.g. the one at fileformat.info (for Java syntax) or rubular.com (Ruby syntax). Those might help you determine the expression you need.

Replace all newlines with space, then split the string with separator ANY_STRING.
