Perl: File: Line: Read: All: How to read all lines in given text file
(s) from command line?

Use the '<>' diamond operator.

This operator gets its data from the file(s) you specified on the
command line.

Steps: Overview:

 1. -Create a Perl file (e.g. 'test.pl') containing this text

--- cut here: begin --------------------------------------------------

while( <> ) {
 print $_;
}

--- cut here: end ----------------------------------------------------

 2. -On the MSDos command line type the command

      perl <your perl filename> <your text file1> <your text file 
2> ... <your text file last>

     e.g.

      perl test.pl ddd1.txt ddd2.txt

     respectively
