Subject: Some perl questions
Message-Id: <bLq27.392823$K5.41256436@news1.rdc1.nj.home.com>


I have the following Perl related questions. Any assistance would be highly
appreciated.

1.  What does the following do ? Does it return the error level ?

$rc = 0xffff & system ( "some command" ) ;

2.  What does the following do ? Is it for initializing ?

$abc = shift ;

3. I have written a couple of cgi scripts which run some system commands.
Say

print "Content type : text/html" ;
 ..
 ...
$abc = `ptree 128` ;
for $i ( 0 .. $#abc ) {
    print "$abc[$i]<BR> " ;
  }
 ....
 ...
The problem with this script is that it does not print the spaces which
appear ( if at all ) before $abc[$i]
So instead of outputing
  10 some proces
         100  some sub process
                 100 some child process

it prints

10 some proces
100  some sub process
100 some child process

How do I fix this ?

Thanks a bunch !
Kevin.
