regex for multiple strings -

i have 2 strings i'm trying match in file , return line.

the first string match i'm looking not completely.

example:

i might looking matcht in matchthisstring match not entire string.

string 1 might come before or after string 2 , might start uppercase or lower case letter.

example:

i might looking have actually.

but , have things matchthisstring.actually or actually.matchthisstring or matchthisstring.someotherjunkidon'tcareabout.actually other combinations that.

i'm having problems using 2 search strings , getting reggae work.

here's example of code works:

 @matches;    while (<$in_fh>) {      #push @matches, $_ if / \q$wanted\e .* \q$prefix\e /x;      #push @matches, $_ if / \q^*(.*)$wanted\s*(.*)\e .* \q^*(.*)$prefix\s*(.*)\e /x;      push @matches, $_ if / \q$wanted\e /x;    } 

what want work 1 of other options that's commented out. don't think i'm joining 2 searches 1 string properly.

thanks in advance assistance.

sounds want

push @matches, $_ if /\q$wanted\e/ , /\q$prefix\e/; 

demo:

$ perl -ne 'use strict; use warnings; use vars qw($wanted $prefix @matches); >    begin {  $wanted = "/donate"; $prefix = "lghfound"; } >    push @matches, $_ if /\q$wanted\e/ , /\q$prefix\e/; print @matches' <<'here' > http://www.google.com/donate > http://lghfoundation.com/pages/donate.html > http://example.com > here http://lghfoundation.com/pages/donate.html http://lghfoundation.com/pages/donate.html
