I'm just poking thru our previous sysadmin's user adding script and saw reference to a ~/.forward file containing the users email address. Any idea what it might be for? It's a tricky one to Google ;-)
The ancient art of Google-fu takes many years to perfect.
But sometimes the most mundane conjurations are the most enlightening.
"what is a linux .forward file for" nets many good results, but they are mostly discussions. For true enlightenment, however, the path is the most difficult because it appears to be so outwardly easy:
".forward file"
;)
