Parse CISCO NEXUS 9xxx/5xxxx show inventory output w/o | json modifier
Python
Parse CISCO NEXUS 9xxx/5xxxx show inventory output w/o | json modifier. Nexus 9xxxx don't have the json output modifier. It's a LINUX based os, so | json would fork a json binary which doesn't exist

Remove single, but not repeating newlines, except immediately after a period. (xiTWA2/1)
PCRE (PHP <7.3)
Intended as a first pass on already word wrapped text, to remove wrap newlines while preserving likely intentional ones. Not especially robust.

Word wrap text
PCRE (PHP <7.3)
(Directly inspired by https://macromates.com/blog/2006/wrapping-text-with-regular-expressions/ ) This version only splits between words, so lines may wrap earlier than the given maximum. Passes existing linefeed through "as‐is", so probably not useful for reflowing already wrapped text
