Re^2: system/exec and %ENV

Thanks a ton for that quick reply... Indeed, as you mentioned, exec was the culprit (I am a n00b ;-) ). The code fragment, nonetheless is here (have commented out the exec) - Thanks again for your help and reply on the dot.:

#!/usr/bin/perl

system "date";



#system 'ls -l $HOME |awk \'{ print $8 }\'';



#exec "date";



#print "$ENV{'PATH'}\n";

#$ENV{'PATH'} = "/home/athampan:$ENV{'PATH'}";

#print "$ENV{'PATH'}\n";





foreach $var (sort keys %ENV)  {

     print "$var => $ENV{$var}\n"

}

Had you used warnings, you'd have got an error message: `use strict; use warnings; exec 'date'; print "still alive\n";` [download] `Statement unlikely to be reached at - line 5.

Unrelated to your original question, but calling out to a shell to get a listing of files is very Rube-Goldberg-ian. See opendir and readdir (and possibly stat if you're interested in the file properties `ls -l` shows). The cake is a lie. The cake is a lie. The cake is a lie.	[reply]

Thanks Hue-Bond and Fletch for your insights. As I mentioned, I am a n00b and "learning perl ... randal et al" and was trying out the commands in the book. As is characteristic n00bishness, I hadn't read the material immediately following the `exec` treatment (I assumed it to function much like the php directive). Thanks all for the kind help (and not yelling at me to go read the book :-) )	[reply] [d/l]
