Another guess what you might want:
Code:
while IFS= read pat
do
  printf "%s match %s times\n" "$pat" $(grep -c "$pat" input_file)
done < pattern_file

Code:
hot.*aaa.* match 2 times
cold.*bbb.* match 1 times
cold.*aaa.* match 2 times

Regexp::Common::list(3) 				User Contributed Perl Documentation				   Regexp::Common::list(3)

NAME
Regexp::Common::list -- provide regexes for lists SYNOPSIS
use Regexp::Common qw /list/; while (<>) { /$RE{list}{-pat => 'w+'}/ and print "List of words"; /$RE{list}{-pat => $RE{num}{real}}/ and print "List of numbers"; } DESCRIPTION
Please consult the manual of Regexp::Common for a general description of the works of this interface. Do not use this module directly, but load it via Regexp::Common. $RE{list}{-pat}{-sep}{-lastsep} Returns a pattern matching a list of (at least two) substrings. If "-pat=P" is specified, it defines the pattern for each substring in the list. By default, P is "qr/.*?S/". In Regexp::Common 0.02 or earlier, the default pattern was "qr/.*?/". But that will match a single space, causing unintended parsing of "a, b, and c" as a list of four elements instead of 3 (with "-word" being "(?:and)"). One consequence is that a list of the form "a,,b" will no longer be parsed. Use the pattern "qr /.*?/" to be able to parse this, but see the previous remark. If "-sep=P" is specified, it defines the pattern P to be used as a separator between each pair of substrings in the list, except the final two. By default P is "qr/s*,s*/". If "-lastsep=P" is specified, it defines the pattern P to be used as a separator between the final two substrings in the list. By default P is the same as the pattern specified by the "-sep" flag. For example: $RE{list}{-pat=>'w+'} # match a list of word chars $RE{list}{-pat=>$RE{num}{real}} # match a list of numbers $RE{list}{-sep=>" "} # match a tab-separated list $RE{list}{-lastsep=>',s+ands+'} # match a proper English list Under "-keep": $1 captures the entire list $2 captures the last separator $RE{list}{conj}{-word=PATTERN} An alias for $RE{list}{-lastsep=>'s*,?s*PATTERNs*'} If "-word" is not specified, the default pattern is "qr/and|or/". For example: $RE{list}{conj}{-word=>'et'} # match Jean, Paul, et Satre $RE{list}{conj}{-word=>'oder'} # match Bonn, Koln oder Hamburg $RE{list}{and} An alias for $RE{list}{conj}{-word=>'and'} $RE{list}{or} An alias for $RE{list}{conj}{-word=>'or'} SEE ALSO
