fellow monks,
I am trying to left justify and condense multiple spaces the output from the "ps" command. I just can't get left justification to work. Help. My code is posted below: 
#!/usr/bin/perl
#
#  ps format
$PSfmt = "\"pid,ppid,pgid,user\"";

#  ps command
$PScmd = `ps -ef -o $PSfmt`;

#
# run the command, output into array
@PSarray = $PScmd ;

#
#  eliminate leading spaces, and condense spaces
for (@PSarray) {s/^\s+//;
                s/ +/ /g;
                print "$_ \n";
          }
exit;

I can do this with "sed" but I prefer to stick to using Perl. 
for $rec (@PSarray)
    {
    $rec = `echo "$rec"|tr -s ' '|sed 's/^ //'`;
    print "$rec\n";
    }
exit;

I hope someone can show me how to do this in Perl.
Thanks in advance.
