jesuashok has asked for the wisdom of the Perl Monks concerning the following question:

all monks, 

#!/usr/bin/ksh

set -x
ls
echo "Hello World"

[download]
In the above shell script we can see the line by line execution when I execute the script. I would like to have the same feature when I execute the perl script too. could anyone recommend a module for this.
I am aware that using the debug we will be able to see the line by line execution as follows :- 
perl -d <program.pl>

[download]
anotherway which, I can use is logging mechanism. But I would like to have some other alternative. could anyone adive me on the same ? It is better If I have the same feature like set -x as shell programming does.

    search.cpan.org is your friend; the second item that shows up for a search for "sh -x" is the answer, Devel::Trace.
