Suppose you have a perl script "test.pl" as below saved with UNIX
line endings in your user directory, and in the same directory you
have three text files "a.txt", "b.txt", "c.txt" ...
#!/usr/bin/perl
foreach $file (@ARGV){
open FILE, $file;
print <FILE>;
}
and at the command prompt you type:
cd; perl test.pl a.text b.txt c.txt
then test.pl will loop through the array of path names -- @ARGV --
and print their contents to STDOUT -- the terminal.
The script can be abbreviated to just this:
for (<>) {print}
In other words, the argument array is whatever follows the script
name in the command line.
