to
Target[server-1.location-5.Swap]: memTotalSwap.0&memTotalSwap.0:public@192.168.5.129:161::::2 - memAvailSwap.0&memAvailSwap.0:public@192.168.5.129:161::::2
in two (in vi):
%s: `/usr/local/bin/snmp_mem_usage.pl public ::g %s/:\(.\+\) real`/ memTotalReal.0\&memTotalReal.0:public@\1:161::::2 - memAvailReal.0\&memAvailReal.0:public@\1:161::::2/
or more generically, reversing stuff:
- %s/(brackets1) stuff (brackets2)/\2stuff\1/g
converts:
brackets1 stuff brackets2
to
brackets2 stuff brackets1
