Hi all

I am normally using the following line to capture the die output into a logfile.

 INIT {$SIG{__DIE__}=sub {LOG_MSG("normal",3,"GENERAL","Script died: $_[0]") and close LOG;}}

Now I am using also Getopt::Long. I don't want to have a logfile generated if somebody is chosing the wrong parameter. Therefore I let the script die with an usage output.

Unfortunately if somebody choses a wrong getopt parameter now - I get a log error message because of the INIT-"die" setting as the log file is not opened yet.

Example:
G:\development\bin>x.pl -x > 4,GENERAL,Script warning: Unknown option: x print() on unopened filehandle LOG at G:\development\bin\x.pl line 45. + ### Version:2.0.0 NAME xxx > 3,GENERAL,Script died: 1 at G:\development\bin\x.pl line 14. ### > 4,GENERAL,Script warning: print() on unopened filehandle LOG at G:\d +evelopment\bin\x.pl line 45. ### print() on unopened filehandle LOG at G:\development\bin\x.pl line 45. + ### 1 at G:\development\bin\x.pl line 14. ### G:\development\bin>

Every line marked with "###" at the end I do not want to have as output to STDOUT.

Do you have an ideas how can fix it? Thanks.

kind regards de Michi

Code:
use strict; use warnings; use Getopt::Long qw(:config no_ignore_case bundling); # Get options / my $VERSION = "2.0.0"; INIT {$SIG{__DIE__}=sub {LOG_MSG("normal",3,"GENERAL","Script died: $_ +[0]") and close LOG;}} INIT {$SIG{__WARN__}=sub {LOG_MSG("normal",4,"GENERAL","Script warning +: $_[0]")}} # Check Flags my $flag_help; my $flag_version; my $flag_config; GetOptions ( 'h|help' => \$flag_help, 'V|VER' => \$flag_version, 'c|config=s' => \$flag_config, ) or die USAGE(); # Check flags and print usage if ($flag_version) { print "Version: $VERSION\n"; exit; } if ($flag_help) { USAGE(); exit; } open(LOG,"> SCRIPTLOG_FILE") or die ("Can't open SCRIPTLOG_FILE: $!\n" +); close LOG; ### subs sub LOG_MSG { my $par_LEVEL = shift (@_); my $par_SEVERITY = shift (@_); my $par_FUNCTION = shift (@_); my @line = @_; print "> $par_SEVERITY,$par_FUNCTION,@line\n"; print LOG "$par_SEVERITY,$par_FUNCTION,@line\n"; } sub USAGE { my ($message)=<<'MESSAGE'; NAME xxx MESSAGE print "Version:${VERSION}\n$message"; }
