Question Using perl to get options from command line

Hi all,
I want to get options from command line by perl.
Code:
usage()
 options:
                -h                    Show this help message and exit
                -t                     Name of tester [Required]
                --timeout           Set the timeout
                -l                      Log and Report output dir
                -r                      Alternative path to testcase scripts
                -s                      Specify the suits of testcases to run
                --testscripts           Specify the testscripts to run
                -p                      Specify the priority of the testcase to run
                -a                      remoteaddress
                -u                      remoteuser
                --remotepasswd          remotepassword
                -o                      Upgrade Framework config file or not

I wrote a perl as followsmy
Code:
    %options=(); 
    getopts("ot:l:r:s: p:a:u:",\%options);
    GetOptions("timeout=s"=> \$options{'timeout'},"testscripts=s@"=>\$options{'testscripts'},"remotepasswd=s"=>\$options{'remotepasswd'});

what's wrong with that?
when I run the script:
Code:
 ./aaa.pl -t Jack -l /logs/ -r /testscripts -s net -p 0 -a 10.22.11.22 -u damon -o

when I print all Options
it says
Code:
Option:
        tester: imeout=400
        timeout:
        logdir: /logs/
        sriptroot: emotepasswd=damon
        suits: net
        testscripts:
        priority: 0
        remoteaddress: 10.22.11.22
        remoteuser: damon
        remotepasswd:

what's wrong with that?
or can you give me a example using getopts and GetOptions?

Thanks
Damon

RAKE(1) 						 Ruby Programmers Reference Guide						   RAKE(1)

NAME
rake -- Ruby Make SYNOPSIS
rake [--f Rakefile] [--version] [-CGNPgnqstv] [-D [PATTERN]] [-E CODE] [-I LIBDIR] [-R RAKELIBDIR] [-T [PATTERN]] [-e CODE] [-p CODE] [-r MODULE] [--rules] [variable=value] target ... DESCRIPTION
Rake is a simple ruby(1) build program with capabilities similar to the regular make(1) command. Rake has the following features: o Rakefiles (Rake's version of Makefiles) are completely defined in standard Ruby syntax. No XML files to edit. No quirky Makefile syntax to worry about (is that a tab or a space?). o Users can specify tasks with prerequisites. o Rake supports rule patterns to synthesize implicit tasks. o Flexible FileLists that act like arrays but know about manipulating file names and paths. o A library of prepackaged tasks to make building rakefiles easier. OPTIONS
--version Display the program version. -C --classic-namespace Put Task and FileTask in the top level namespace -D [PATTERN] --describe [PATTERN] Describe the tasks (matching optional PATTERN), then exit. -E CODE --execute-continue CODE Execute some Ruby code, then continue with normal task processing. -G --no-system --nosystem Use standard project Rakefile search paths, ignore system wide rakefiles. -I LIBDIR --libdir LIBDIR Include LIBDIR in the search path for required modules. -N --no-search --nosearch Do not search parent directories for the Rakefile. -P --prereqs Display the tasks and dependencies, then exit. -R RAKELIBDIR --rakelib RAKELIBDIR --rakelibdir RAKELIBDIR Auto-import any .rake files in RAKELIBDIR. (default is rakelib ) -T [PATTERN] --tasks [PATTERN] Display the tasks (matching optional PATTERN) with descriptions, then exit. -e CODE --execute CODE Execute some Ruby code and exit. -f FILE --rakefile FILE Use FILE as the rakefile. -h --help Prints a summary of options. -g --system Using system wide (global) rakefiles (usually ~/.rake/*.rake ). -n --dry-run Do a dry run without executing actions. -p CODE --execute-print CODE Execute some Ruby code, print the result, then exit. -q --quiet Do not log messages to standard output. -r MODULE --require MODULE Require MODULE before executing rakefile. -s --silent Like --quiet, but also suppresses the 'in directory' announcement. -t --trace Turn on invoke/execute tracing, enable full backtrace. -v --verbose Log message to standard output (default). --rules Trace the rules resolution.
