Hello Dave,
#!/usr/bin/perl
use strict; use warnings;
my $from1 = $ENV{'SIP_HF_FROM'};
print $from1;
__END__
I get: Use of uninitialized value in print at test.pl line 8.
When I type "set" at the command line, I do see the variable SIP_HF_FROM ... ... SHLVL=1 SIP_HF_FROM=sip:+16364424593 SIP_RURI=BLAH2 ...
Is it that there is a bad character in the variable that I dont know about? Any help is appreciated as always. I hope I explained myself well enough.
No the error means its not initialized :)
Try seeing what %ENV is:
#!/usr/bin/perl
use strict; use warnings; use Data::Dumper;
pritn Dumper \%ENV;
To see what %ENV looks like to perl.
or even quicker:
perl -mstrict -MData::Dumper -we 'print Dumper \%ENV;'
You can avoid the error by initializing it:
$ perl -mstrict -we 'print $ENV{SIP_HF_FROM};'
Use of uninitialized value in print at -e line 1.
$ perl -mstrict -we '$ENV{SIP_HF_FROM} = "" if !defined $ENV{SIP_HF_FROM};print $ENV{SIP_HF_FROM};'
$
Thanks in advance,
No problem :)
