Search between two words in a file
How can I search between two words in a file using perl e.g. a file contains some paragraphs and in each paragraph there are some words between "FROM" and "WHERE". My query is how to search between these two words and store the data.

One way would be to read each paragraph into a single variable
(either by setting $/ or by appending line to the variable until you get to the end of the paragraph), then simply match using something like $paragraph=~/FROM(something wild)WHERE/;

To the Original Poster:
The manuals perldoc perlrequick and perldoc perlre describe it quite well.
You will understand matija's solution after a quick glance into one of them and be able to use it.
$paragraph =~ m/FROM(.*?)WHERE/; # now everything in between is in $1
my $inbetween = $1;
If that still doesn't make much sense, everything else can be found in perldoc perlintro.

can you give me the command used for appending line to a variable until end of line. and after matching the data using "$paragraph=~/FROM(something wild)WHERE/;", how can I print that variable?
