Blank Lines in a Perl Script
 

Hi all,

I am a total newbie at Perl and was just asking if there is a way to add line spaces when asking for user interaction in a script.

For example:

So this is asking a question but has a space/empty line at the top of the screen and 2 spaces/empty lines below. I've seen it done in a bash script using for each line/space needed

So what does perl use??

Sorry if its a dumb question to most of you all.

Thanks in advance.

Hello,

You could use a standard regular expression within your print statement, such as \n which means new line. For a list of all regular expressions used, see here: http://www.ryerson.ca/perl/manual/pod/perlre.html

Thanks I will check that out.

No problem! If you have any more questions, feel free to ask. Mark my posts helpful if you feel the need to also, thanks!

Small amendment for completeness' (& correctness') sake:
"\n" in the context of print (or any string, really) is simply
an escape sequence, not a regular expression; while the escape
sequence has a meaning in REs (same meaning as in a string,
matching a newline) it is NOT an RE in this context.

I knew that man :) I refered to the regular expressions because you can also use expressions to create blank and new lines. Thanks for clarifying that though, since I forgot to.

Cheers,
