For multiline problems, you need a looper, a script that has an N, a $ test and a branch t or b, so you can pile up lines in the buffer. Duplicates would need to be sorted to be adjacent, and 'sort -u' or 'uniq' if already sorted, will get them, simpler. You do not have associative arrays like bash, awk, perl in sed to record all and detect dups in an unsorted file.

Don't think of it as one sed command, but one sed instance running a script.

5 and 6 are just this script line: s/[)(]/\\&/g

I find it is better to put looper functionality in a separate sed instance on the pipe. Sometimes, for speed, I chain many sed in a row, so each holds the line the least time.

NAME

       pmdabonding - Linux bonded interface performance metrics domain agent (PMDA)

DESCRIPTION

       pmdabonding is a Performance Metrics Domain Agent (PMDA) which exports metric values from bonded network interfaces in the Linux kernel.

INSTALLATION

       If you want access to the names and values for the bonding performance metrics, do the following as root:

	       # cd $PCP_PMDAS_DIR/bonding
	       # ./Install

       If you want to undo the installation, do the following as root:

	       # cd $PCP_PMDAS_DIR/bonding
	       # ./Remove

       pmdabonding is launched by pmcd(1) and should never be executed directly.  The Install and Remove scripts notify pmcd(1) when the agent is
       installed or removed.

FILES

       $PCP_PMDAS_DIR/bonding/Install
	   installation script for the pmdabonding agent

       $PCP_PMDAS_DIR/bonding/Remove
	   undo installation script for the pmdabonding agent

       $PCP_LOG_DIR/pmcd/bonding.log
	   default log file for error messages from pmdabonding
