This works . I have seen this error before . That time it was because I was missing a semi colon. I suspect its the same in your case

Code:
echo "enter file name " ; read input ; if [ -e $input ]; then echo "$input fo
und"; else echo "$input not found"; fi
enter file name
ntsuser.ini
ntsuser.ini not found


 echo "enter file name " ; read input ; if [ -e $input ]; then echo "$input fo
und"; else echo "$input not found"; fi
enter file name
ntuser.ini
ntuser.ini found

Mail::Mbox::MessageParser::Perl(3)			User Contributed Perl Documentation			Mail::Mbox::MessageParser::Perl(3)

NAME
Mail::Mbox::MessageParser::Perl - A Perl-based mbox folder reader SYNOPSIS
#!/usr/bin/perl use Mail::Mbox::MessageParser; my $filename = 'mail/saved-mail'; my $filehandle = new FileHandle($filename); my $folder_reader = new Mail::Mbox::MessageParser( { 'file_name' => $filename, 'file_handle' => $filehandle, } ); die $folder_reader unless ref $folder_reader; # Any newlines or such before the start of the first email my $prologue = $folder_reader->prologue; print $prologue; # This is the main loop. It's executed once for each email while(!$folder_reader->end_of_file()); { my $email = $folder_reader->read_next_email(); print $email; } DESCRIPTION
This module implements a Perl-based mbox folder reader. Users must not instantiate this class directly--use Mail::Mbox::MessageParser instead. The base MessageParser module will automatically manage the use of faster implementations if they can be used. METHODS AND FUNCTIONS The following methods and functions are specific to the Mail::Mbox::MessageParser::Perl package. For additional inherited ones, see the Mail::Mbox::MessageParser documentation. $ref = new( { 'file_name' => <mailbox file name>, 'file_handle' => <mailbox file handle> }); <file_name> - The full filename of the mailbox <file_handle> - An opened file handle for the mailbox The constructor for the class takes two parameters. The optional file_name parameter is the filename of the mailbox. The required file_handle argument is the opened file handle to the mailbox. Returns a reference to a Mail::Mbox::MessageParser object, or a string describing the error. BUGS
