Find the String "house[1]" in Another String?

| Faethon 2004-03-29, 4:39 am |
| I know that "[" and "]" are special characetrs for
Perl/CGI. However, I need to find the strings, say,
house[1] and house[2] in a given text file.
Naturally, "house[1], "house[2]" do not work.
But "house\[1\]", "house\[2\]" do not work either.
What strings should I actually use to look for them?
Thanks.

Well,
I figured it out after several hours!
I look for "\Qhouse[1]\E" and "\Qhouse[2]\E".
Thanks!

Do you? What has CGI to do with it?
Those are special characters in Perl regular expressions.

Yes, they do.
Show us the code that made you draw that incorrect conclusion.

But all that does is convert them into "house\[1\]" and "house\[2\]" -
which you already said _didn't_ work[1].
$ perl -le 'print "\Qhouse[1]\E"'
house\[1\]
Dave...
[1] But I strongly suspect that you were wrong to say that.
