Re: Re: URGTENT: Need to remove undescore characters

[markinoz]

Hi thanks for your help. I didnt write the survey script, Im only trying to hack it for aesthetics sake. My client didnt like how the title looked with _ chars in it. Anyway I added the code you suggested ( I use seach and replace every day thru command line for line breaks etc ) so maybe I didnt explain myself correctly, I knew how to do the replace just wasnt sure of the structure for it. Again thanks and heres what I added

$String = "$survey"; 
$String =~ s/_/ /g;

then called $string instead of $survey in the html title simple huh?? see you around and thanks for everyone who posted. p.s. when the boss gives me a few minutes to breath Ill read the links as suggested. Mark R

You're welcome... it's good to see people learn, to be honest i often have to look up the most basic things myself.

One minor hint:
When you want to assign the value of one variable to another, you needn't quote the original variable.

Hence,

$String = "$survey";

is actually better written as:

$String = $survey;

Perl is flexible enough to live with the first version, but that ability was really meant more for things like this:

if ($something) {
    # do some stuff
}
else {
    # there was an error, set it
    $error = "informative error message";
    $error_num = 45;
}

print STDERR "Error $error_num    $error";

This will (if there was an error, ie $something was not true) produce:
Error 45    informative error message on the STDERR output (or in a logfile, or wherever you printed the error)

In any case, please do take a look at those other links in this thread, if you read/heed them, you'll actually get better answers much more quickly at this site.

have a great day!
