what is wrong with parsing the pipe | sed command

Question

Testing some new scripts I came across this issue as part of the ps_redirect.sh now

If I issue the command at the CLI using tmsh I can see that I get the desired outcome which is to bring the irule currently in use. I had to manipulate the result using sed to bring the second word after a match is found {2n;p} as you can find below

[root@bigip4k01:Active:In Sync] Scripts # tmsh list /ltm virtual /PSoft1/fn89prd_lexingtonky_ssl |sed -n '/Finance_Redirect/{2n;p}'
        Finance_Redirect
[root@bigip4k01:Active:In Sync] Scripts #

However when executing it from the shell script using open or close options as part of the prompt to action upon this input, I am not being able to parse it correctly using the delimiter | (pipe) command followed by sed as you can see below:

[root@bigip4k01:Active:In Sync] Scripts # ./ps_redirect.sh open hr9prd,fn89prd,hr9job,hr9pwd honor auto active

Any idea of how to parse the | (pipe) followed by sed? Maybe a double quote or single quote required somewhere? Let me know if you know how to parse the | (pipe) followed by sed correctly please.

Thank you once again.

Usage: ${0} <direction> <system> <maint window> <peer update>

   direction    - redirect or remove a redirect
                  'close' - redirect
                  'open' - remove redirection
                  'test' - runs program but commands/logs are sent to 
                           the for inspection
   system       - the system name(s) to change rules for:
                  'fn89prd', 'hr9prd', 'hr9job', 'epm9prd', 'hr9pwd'
                  'all' for all defined systems 
                  use ',' to seperate multiple options
                  use '-' for none sync operation
   maint window - when 'honor' is used, then the script will not make
                  any changes unless it is maintenance week; use 'force' to
                  run and make change irrespective to maintenance window

   peer update  - if 'preserve' then no attempt is made to update the peer.
                  if 'auto' is used then a warning is raised if the peer has
                  changes and the peer is not overwritten.
                  if 'overwrite' is used then the current config will 
                  overwrite peer regardless of it's sync state.
                  if 'manditory' then the peer must be in sync for the local 
                  change to occur and the config is pushed to the peer

   Status       - Active or Standby; the system must be in this status.
                  If Ignore specified then the check is not performed and
                  the change will occur regardless of current status.
