Unable to open a file in perl

Not able to open a file using this code

why not?

Code:
use strict; 
use warnings;
my $file = "verInfo.txt";
unless(open FILE, $file) {
 # Die with error message
 # if we can't open it.
 die "\nUnable to open $file\n";
}
my $line = <FILE>;
print $line;
close FILE;

NAME
medit - text editor SYNOPSIS
medit [OPTION]... [FILES] DESCRIPTION
medit is a text editor. OPTIONS
-n, --new-app run new instance of medit. By default medit opens FILES (or creates a new document if none are given) in an existing instance of application -s, --use-session[=yes|no] load and save session. By default medit does it when -n is not used. If this option is not given on command line then medit uses the corresponding preferences setting. --pid PID use existing instance with process id PID. --app-name NAME use instance name NAME. If an instance with this name is already running, then it will send files given on the command line to that instance and exit. -e, --encoding ENCODING use provided character encoding to open the file -l, --line LINE open file and position cursor on line LINE. Alternatively line number may be specified with filename, e.g. medit foo.txt:12 -r, --reload automatically reload opened file if it was modified on disk by another program. -w, --new-window open file in a new window. -t, --new-tab open file in a new tab. --log-file FILE write debug output into FILE. This option is only useful on Windows. --log-window show debug output in a log window. This option is only useful on Windows. --debug DOMAINS enable debug output for DOMAINS (if medit was compiled with --enable-debug option). --geometry WIDTHxHEIGHT --geometry WIDTHxHEIGHT+X+Y default window size and position. -h, --help show summary of options. -v, --version show program version. FILES list of files to open. Filenames may include line numbers after colon, e.g. /tmp/file.txt:200. Trailing colon is ignored. ENVIRONMENT VARIABLES
MEDIT_PID if set, it is used as --pid argument. When medit spawns a process (e.g. a DVI viewer) it sets MEDIT_PID to its own process id, so the child process may in turn simply use 'medit filename' to open a file (e.g. for inverse DVI search). CONTACT
