Sed in vi - \r and \n not giving desired results

I use many different machines at work, each with different versions of o/s's and installed applications. Sed in vi is particularly inconvenient in the sense that sometimes it will accept the "\r" as a carriage return, sometimes not. Same thing with "\n". For instance, if I have a list of hosts...

awk - saving results of external script to variable.

plockstat

PLOCKSTAT(1)															      PLOCKSTAT(1)

NAME

       plockstat - front-end to DTrace to print statistics about POSIX mutexes and read/write locks

SYNOPSIS

       plockstat [-vACHV] [-n count] [-s depth] [-e secs] [-x opt[=val]]
       command [arg...]

       plockstat [-vACHV] [-n count] [-s depth] [-e secs] [-x opt[=val]]
       -p pid

OVERVIEW

       The plockstat command is a front-end to DTrace that can be used to print statistics about POSIX mutexes and read/write locks.

       Since OS X 10.11, in order to use this, your process must be run with DYLD_LIBRARY_PATH set to contain /usr/lib/system/introspection:

	       DYLD_LIBRARY_PATH=/usr/lib/system/introspection

       Which contains the necessary static DTrace probes.

OPTIONS

       -v     print a message when tracing starts

       -A     trace contention and hold events (same as -CH)

       -C     trace contention events for mutexes and rwlocks

       -H     trace hold events for mutexes and rwlocks

       -V     print the dtrace script to run

       -n count
	      display only 'count' entries for each event type

       -s depth
	      show stack trace upto 'depth' entries

       -e secs
	      exit after specified seconds

       -x arg[=val]
	      enable a DTrace runtime option or a D compiler option

       -p pid attach and trace the specified process id
