This really works good, but i cudnt exactly understand the logic behind it. I'm aware NF is for no. of fields in each line and \n is for newline.
But i cudnt understand the whole logic, if u cud explain me, that be really helpful for me to make changes to this in future.
Grateful to your comments.
Many Thanks!

Thanks for all ur comments. It works weel and good.
....
printf print without a newline
NF?$0:"\n" a conditional expression.
test_condition ? true_result : false_result
NF return 0 for blank lines. Zero is considered false.
$0 returns the whole line/record being considered
"\n" adds a newline to the output when NF is zero

I wrote my own long winded versions of the concise:
This one is just a verbose version of the above version:
This one actually breaks the fields down properly in case you need to process them but outputs field and record separators manually:

platform::shell
platform::shell(n) Tcl Bundled Packages platform::shell(n)
__________________________________________________________________________________________________________________________________________________NAME
platform::shell - System identification support code and utilities
SYNOPSIS
package require platform::shell ?1.1.4?
platform::shell::generic shell
platform::shell::identify shell
platform::shell::platform shell
_________________________________________________________________DESCRIPTION
The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.
This package allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
requirement is that the other shell (identified by its path), is actually executable on the current machine.
While for most platform this means that the architecture of the interrogated shell is identical to the architecture of the running shell
this is not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.
For applications like a code repository it is important to identify the architecture of the shell which will actually run the installed
packages, versus the architecture of the shell running the repository software.
COMMANDS
platform::shell::identify shell
This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.
platform::shell::generic shell
This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.
platform::shell::platform shell
This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
KEYWORDS
operating system, cpu architecture, platform, architecture
