So how would you pass the -v (plus version info) to cver? Like cver -c -v 12.3R, i.e. second and third parameter? What error checking needs to be done?

I am performing a grep command and I need to know how to echo "NONE" or "0" to my file if grep does not find what i am looking for.
echo What i found >> My_File
grep "SOMETHING" >> My_File
I am sure this is easy, I am sort of new at this!

log::handler::levels
Log::Handler::Levels(3pm) User Contributed Perl Documentation Log::Handler::Levels(3pm)
NAME
Log::Handler::Levels - All levels for Log::Handler.
DESCRIPTION
Base class for Log::Handler.
Just for internal usage and documentation.
METHODS
Default log level
debug()
info()
notice()
warning(), warn()
error(), err()
critical(), crit()
alert()
emergency(), emerg()
Checking for active levels
is_debug()
is_info()
is_notice()
is_warning(), is_warn()
is_error(), is_err()
is_critical(), is_crit()
is_alert()
is_emergency(), is_emerg()
Special level
fatal()
Alternative for the levels "critical" - "emergency".
is_fatal()
Check if one of the levels "critical" - "emergency" is active.
Special methods
trace()
This method is very useful if you want to add a full backtrace to your message. Maybe you want to intercept unexpected errors and want
to know who called "die()".
$SIG{__DIE__} = sub { $log->trace(emergency => @_) };
By default the backtrace is logged as level "debug".
# would log with the level debug
$log->trace('who called who');
If you want to log with another level then you can pass the level as first argument:
$log->trace(info => $message);
dump()
If you want to dump something then you can use "dump()". The default level is "debug".
my %hash = (foo => 1, bar => 2);
$log->dump(\%hash);
If you want to log with another level then you can pass the level as first argument:
$log->dump($level => \%hash);
die()
This method logs the message to the output and then call "Carp::croak()" with the level "emergency" by default.
$log->die('an emergency error here');
If you want to log with another level, then you can pass the level as first argument:
$log->die(fatal => 'an emergency error here');
log()
With this method it's possible to log messages with the log level as first argument:
$log->log(info => 'an info message');
Is the same like
$log->info('an info message');
and
$log->log('an info message');
If you log without a level then the default level is "info".
