Please recommend a regular expression excluding return character...

All-

Can anyone recommend a regular expression that excludes the return
character?

My objective is to find occurances of a string WITHIN A LINE of a text
file. Thus, if givein some_string1 and some_string2, match:

<some_string2>

Thanks!

The '.' doesn't match newlines.

In other words:

/#{some_string1}.#{some_string2}/

If you use readline or gets you don't even need to bother with the
newlines:

File.open("file.txt", "r") do |f|
while ( line = f.gets )
line.chomp!

if /my_regexp/ =~ line
puts "Found it!"
end
end
end

Otherwise omitting the /m flag at the regexp avoids "." to match the
newline.
