For learning purposes I would appreciate if some one can suggest a more concise approach (even if it comes at the cost of readability).

Taking you at you word; you can do this extremely concisely with a one-liner:

perl -ple1 file1 file2 ...

[download]

Or, if you prefer it as a 'full program'; type this into a file called ptype.pl:

#! perl -pl

[download]

And then on your command line:

ptype file1 file2 file3 file4 ...

[download]

If you're using *nix, then it would have to be (something like):

#!/usr/bin/perl -pl

[download]

With the advantage of being able to use wilcards:

ptype *.pl *.txt

[download]
With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
