Question
Thank you vino and casphar!
I was invoking the script just by entering the name of the script (i.e. without "./" or ". ./").

I was trying to use this inside the code below (invoking it by . ./script.ksh)


Code:
#!/bin/ksh

echo "Enter folder name: \c"
read folder

#Remember current path to go back when loop finishes

pwd > current_path

#Start Loop

for file in `ls $folder`
do
      cd $folder
      mv $file new_$file
      cd | echo $current_path
done

rm current_path

... and it does modify the files in the given directory (folder_name) correctly however it gives the error below:

ksh: current_path: parameter not set
ksh: folder_name: not found
ksh: current_path: parameter not set
ksh: folder_name: not found
ksh: current_path: parameter not set
ksh: current_path: parameter not set
rm: current_path non-existent

Could someone tell me why I'm getting this error and how I can stop this error to appear?

cpanplus::shell

CPANPLUS::Shell(3perl)					 Perl Programmers Reference Guide				    CPANPLUS::Shell(3perl)

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.

       Please report bugs or other issues to <bug-cpanplus@rt.cpan.org<gt>.
