Working out percentage in shell script
Hi All,
I currently have a shell script which is pulling multiple counters from various sources. Due to the counters being cumulative counters I've got some code to work out the delta from the last reading and current which is working fine.

The problem i have now is being able to work out the success rate as a percentage.

Normally I would just take success and divide by attempts then multiply this by 100 which would give my success rate at a percentage (i'd like it to 2 decimal places).

How can this be done in a shell script ?

Any help is apprecaited as always.

Thanks

ibqueryerrors

IBQUERYERRORS(8)						OpenIB Diagnostics						  IBQUERYERRORS(8)

NAME

       ibqueryerrors.pl - query and report non-zero IB port counters

SYNOPSIS

       ibqueryerrors.pl [-a -c -r -R -C <ca_name> -P <ca_port> -s <err1,err2,...> -S <switch_guid> -D <direct_route> -d]

DESCRIPTION

       ibqueryerrors.pl  reports  the  port  counters  of  switches.   This  is similar to ibcheckerrors with the additional ability to filter out
       selected errors, include the optional transmit and receive data counters, report actions to remedy a non-zero count, and report	full  link
       information for the link reported.

OPTIONS

       -a     Report an action to take.  Some of the counters are not errors in and of themselves.  This reports some more information on what the
	      counters mean and what actions can/should be taken if they are non-zero.

       -c     Suppress some of the common "side effect" counters.  These counters usually do not indicate an error condition and can be usually be
	      safely ignored.

       -r     Report  the port information.  This includes LID, port, external port (if applicable), link speed setting, remote GUID, remote port,
	      remote external port (if applicable), and remote node description information.

       -R     Recalculate the ibnetdiscover information, ie do not use the cached information.	This option is slower but should be  used  if  the
	      diag tools have not been used for some time or if there are other reasons to believe that the fabric has changed.

       -s <err1,err2,...>
	      Suppress the errors listed in the comma separated list provided.

       -S <switch_guid>
	      Report results only for the switch specified. (hex format)

       -D <direct_route>
	      Report results only for the switch specified by the direct route path.

       -d     Include the optional transmit and receive data counters.

       -C <ca_name>    use the specified ca_name for the search.

       -P <ca_port>    use the specified ca_port for the search.
