One more thing. But I am not clear why the ; after condition is really needed or not
Take an easier example, the
date and
who commands. If we want to run both commands, we might use two lines:
date
who
or we can enter both commands on a single line if we use the semicolon like this:
date ; who
But we gotta have something separating the two commands. Usually we have the newline character as the delimiter between commands, but the semicolon also works.
So it's a matter of style whether you use
if [ ... ] ; then
or
if [ ... ]
then
I like the first style because it lets more of the script be visible on a page. But I wouldn't call the second style "wrong".

CPANPLUS::Shell(3pm) Perl Programmers Reference Guide CPANPLUS::Shell(3pm)
NAME
CPANPLUS::Shell - base class for CPANPLUS shells
SYNOPSIS
use CPANPLUS::Shell; # load the shell indicated by your
# config -- defaults to
# CPANPLUS::Shell::Default
use CPANPLUS::Shell qw[Classic] # load CPANPLUS::Shell::Classic;
my $ui = CPANPLUS::Shell->new();
my $name = $ui->which; # Find out what shell you loaded
$ui->shell; # run the ui shell
DESCRIPTION
This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
shell.
Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
loading class), so please consult the documentation of your shell of choice.
BUG REPORTS
Please report bugs or other issues to <bug-cpanplus@rt.cpan.org<gt>.
