( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Thank you all for the help.

Figured it out.

To error is human. To really screw things up required a computer!

Perl 5: how to read rom a pipe and command line parameter at the same time:

PeadPipe.pm

package ReadPipe; require Exporter; use strict; use warnings; use diagnostics; # use diagnostics "-verbose"; use Term::ReadKey qw ( ReadKey ReadMode ); # our @ISA = qw( Exporter ); use Exporter qw(import); our @EXPORT = qw(); # symbols to be exported by default (space- +separated) our $VERSION = 0.01; our @EXPORT_OK = qw( ReadPipe ); # Refernece: https://metacpan.org/pod/Term::ReadKey # ReadMode MODE [, Filehandle] # # Takes an integer argument, which can currently be one of the foll +owing values: # # 0 Restore original settings. # 1 Change to cooked mode. # 2 Change to cooked mode with echo off. # (Good for passwords) # 3 Change to cbreak mode. # 4 Change to raw mode. # 5 Change to ultra-raw mode. # (LF to CR/LF translation turned off) # # Or, you may use the synonyms: # # restore # normal # noecho # cbreak # raw # ultra-raw

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
