Convert Form Feed to new line

Bluejay07 · Aug 24, 2016

Hello,

I have never used Perl although I'm trying to modify some code.

From a unix system, a line of text might end with \f\n.
Is it possible to convert \f to \n so that the line would end with \n\n?

I have found the following although it doesn't appear to work.

Code:

$temp=~s/\f/\n/g;

I could also remove the \n and then \f

Code:

    if ($temp=~/\n/) {
      chop($temp);
      }
    if ($temp=~/\f/) {
      chop($temp);
      }

Do this, I would like to add a \n although I'm not sure how.
I've tried a few things, such as

Code:

$temp=$temp."\n";

I don't know if I'm even using proper syntax or not.

Any help would be appreciated.

Thanks.

There is no [tt]\f[/tt] char in Windows systems output strings, [tt]\r[/tt] might be used instead.
With Perl you simply use [tt]\n[/tt] that is converted, when sent to an output device, to the proper sequence depending on operating system.
If you want an additional new line in your string, just append a newline char: [tt]$temp.="\n";[/tt]

Hi prex1,

Thanks for the reply.
The file is being created on a unix system, processed through a program to convert it to a pdf file then viewed on a windows system.
I'm not entirely certain although I'm relatively confident that the file does have a \f.

I'll try your suggestion for appending a newline character.

Thank you.

the unix shell command tr (translate) is often used to accomplish that conversion
