foreach my $word (keys %count_hash)
{
            print $word," Comes for ",$count_hash{$word}," times\n";
}

The output I am getting is follows

Code:
6 Comes for 1 times
4 Comes for 1 times
3 Comes for 1 times
2 Comes for 2 times

strip_stx(1)						      General Commands Manual						      strip_stx(1)

NAME
strip_stx - a simple literate programming tool SYNOPSIS
strip_stx [ -c commentchars ] [ -B open close ] [ file file ... ] DESCRIPTION
strip_stx takes all structured text (Stx) markup away from the listed files, leaving only text in preformatted blocks. If no files are listed, standard input is read instead. The result is written to standard output. This is intended as a simple literate programming tool: programmers may write their programs as documents, processing them with stx2any for documentation and publication but with strip_stx for compilation / running the code. More information about Stx is on the manpage of stx2any. OPTIONS
-c commentchars comment out the non-code portions (text outside preformatted blocks) with the given commentchars at the beginning of every line. If this option (or the next one) is not given, non-code portions are simply deleted. -B open close surround the non-code portions with (comment-)opening and closing markers open and close respectively. This option can be used together with the -c option. --version, -V Just show version information and exit. --help, -? Just show a short help message and exit. EXAMPLES
strip_stx parse.py.stx > parse.py Strip documentation away from the source file parse.py.stx, supposedly only leaving python code there. strip_stx -B '/*' ' */' -c ' * ' my.c.stx > my.c Make a literate C code document into proper C source file, leaving the documentation in neatly-formatted comments. strip_stx -B 'cat < < EOT' 'EOT' embshell.stx > embshell.sh Turn the document embshell.stx into an "embedded shell" script, where all non-program portions are printed to the standard output when exe- cution reaches them. This is akin to PHP or eperl; but strip_stx is not really meant for this. There are other options for making embed- ded scripts, such as defining your own markup for the code portions or handling the program logic with m4 within stx2any. SEE ALSO
