Compressed data embedded in script
I have about 60 MB of text data I want to include at the bottom of a script. 60 MB is too big for us, but compressed it would be probably only 3-6 MB which is much better. Is there any way to put gzipped data in the DATA section of a script, and conveniently read it? I'd also prefer that my script be able to survive getting passed through a terminal -- is it hard to encode the data block (MIME perhaps?) so it will?

Change character code 160 to 32
I want to change character code 160 to character code 32 throughout a bunch of text files. I'm using this right now s/(.)/ord($1) == '160' ? chr(32) : $1 /eg; and it works, but I don't like it much. If anybody has another way they like better, I'd appreciate seeing it. It does not have to be a reg exp. Anybody know why this doesn't work? tr/\160/\32/d; Oddly it replaces 'p' (character code 80) with character code 26??? I get the digest version, so may not respond right away.

Well, Shawn gave you the correct answer, I'll just explain why it didn't work for you. The reason it doesn't is because \DDD uses octal digits - not decimal ones: http://en.wikipedia.org/wiki/Octal Regards, Shlomi Fish I get the digest version, so may not respond right away.

I'm using this right now s/(.)/ord($1) == '160' ? chr(32) : $1 /eg; Here you are using the decimal numbers 160 and 32. This is very inefficient as you are searching for *every* character (except newline) and replacing every character. It would be much simpler and more efficient to just search for the character you want and replace only that character: my $search = quotemeta chr 160; my $replace = chr 32; s/$search/$replace/g; and it works, but I don't like it much. If anybody has another way they like better, I'd appreciate seeing it. It does not have to be a reg exp. Anybody know why this doesn't work? tr/\160/\32/d; Oddly it replaces 'p' (character code 80) with character code 26??? The escape sequences you are using are octal (not decimal) representations of the ordinal values of the characters. You have to convert the decimal values 160 and 32 to the octal values 240 and 40. $ perl -le'printf %d decimal = %o octal and %d decimal = %o octal\n, 160, 160, 32, 32' 160 decimal = 240 octal and 32 decimal = 40 octal So it then becomes: tr/\240/\40/; (You do not need the /d option as you are not deleting any characters.) Or using substitution: s/\240/\40/g; John -- The programmer is fighting against the two most destructive forces in the universe: entropy and human stupidity. -- Damian Conway -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/

Hi Slick! On Sunday 04 Oct 2009 20:02:36 Slick wrote: I am new at this perl thing. I just want to know tips and simple scripting. I also use strawberry perl for my program. Strawberry Perl is a very fine choice for Perl on Windows - probably better than ActivePerl by now.

Perl Questions
I have a couple of questions. What is a good starter perl book to learn perl. Secondly, I am kinda having trouble assimilating all the perl information. I want to know ways that you all remember the format of a script as well as the main items that are normally use. I know about the Scalars (word for a word with $ used. $a=2), Array (several items @b= (1, 2, 3). I am just having problems figuring out when and where they would be used and to a point reading a script. Hope you don't mind my questions.
