Dear list:
Sorry to distrub all .
When I learned Perl on the book called "Perl by example 4th
Chinese Edition ", I found there was an error on this book .
There had a perl script writted by this :
#!/usr/bin/perl
print << 'END';
echo Today is
date
END
The book said the script would display this :
Today is
Fir Oct 27 12:48:36 PDT 2007
But when I put it on my OS called CentOS 5.3 and run it
,the output like this :
echo Today is
date
I also write it like this :
#!/usr/bin/perl
$now =`date`;
print <<END;
Today is $now
END
This script will be displayed t this "Today is Wed
Oct 18:38 CST 2009"
Is it an error of the book ?Or Can the Perl would
execute the Shell command in here document with the signal quotes?
Thanks in advance ~~~~
