fancy find replace

uses match substitution. (X) -> \1

convert:

Target[server-5.location-5.mem]: `/usr/local/bin/snmp_mem_usage.pl public 192.168.5.5 real`

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

No wrap

:set nowrap

Convert to unix file format

For example:
