Help !! perl open function
Help Please perl Gurus,

I am trying to add ungrouped passengers in a group and I creating a script however it fails on first step only I tried all the options it returns following error.

syntax error at junki line 4, near "open "
Execution of junki aborted due to compilation errors.
at junki line 14

Here is my code
Code:
#!/usr/bin/perl -w 
$bookid = 3456 
 
open (LSOUT, "res_list -avail -bookid $bookid |" ); 
while ($LINEINc = <LSOUT>) 
{ 
  chomp ($LINEINc); 
  if ( $LINEINc =~ "no/name") 
  { 
    print "$passid\n"; 
  } 
} 
close (LSOUT); 
exit;

Usually I use following commands to do it manually.
Code:
# res_list -avail 
ID Availability Pass Name GroupName Total Pass 
0050 booked abc xyz no/name's 8 
0051 booked abc xyz roth 8 
0052 booked abc xyz no/name's 8 
0053 booked abc xyz no/name's 8 
0054 booked abc xyz bengal 9 
0055 booked abc xyz no/name's 9 
0056 booked abc xyz brown 9 
0057 booked abc xyz no/name's 9 
0058 booked abc xyz eagle 9 
0059 booked abc xyz no/name's 9 
005A booked abc xyz no/name's 9

select only 3 ID's where group name is noname and list them in a comma saperated format like 0050,0052,0053....

then run following command to make sure they are not member any other groups.
Code:
#search_grp -passid 0050,0052,0053 

ID Group Name Pass. Count loc Count 
---- -------------------------------- ----- ----- 
0050 - - - 
0052 - - - 
0053 - - -

if they are not member of any group then print in the following format in file - name grpid_class
Code:
create group ID 0050, class=leisure; 
copy id 0052 to group id 0050; 
copy id 0053 to group id 0050;

once they are displayed to user run the file in following command
Code:
#create_group -f 0050_leisure

succuessful display message.

perl::critic::policy::inputoutput::requirecheckedopen

Perl::Critic::Policy::InputOutput::RequireCheckedOpen(3pUser Contributed Perl DocumentatPerl::Critic::Policy::InputOutput::RequireCheckedOpen(3pm)

NAME

       Perl::Critic::Policy::InputOutput::RequireCheckedOpen - Write "my $error = open $fh, $mode, $filename;" instead of "open $fh, $mode,
       $filename;".

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       The perl builtin I/O function "open" returns a false value on failure. That value should always be checked to ensure that the open was
       successful.

	   my $error = open( $filehandle, $mode, $filename );		       # ok
	   open( $filehandle, $mode, $filename ) or die "unable to open: $!";  # ok
	   open( $filehandle, $mode, $filename );			       # not ok

	   use autodie;
	   open $filehandle, $mode, $filename;				       # ok

       You can use autodie, Fatal, or Fatal::Exception to get around this.  Currently, autodie is not properly treated as a pragma; its lexical
       effects aren't taken into account.

CONFIGURATION

       This Policy is not configurable except for the standard options.
