well.. I just checked with Solaris' awk.. and it doesn't do it like
this...
echo "sdlfk/sdfkj " | awk -F/ "{printf $NF }"
so the real fix is stop uname for including that extra space... also..
it would fundamentally break awk... with awk you expect to get
everything EXACTLY between the field seperator (except for in the special
case the man page mentions)... there is no extra field seperator between
the end of text and the new line... so the space is part of the field...
I personally would object to this modification the awk.. and hope that
this crazy idea doesn't every get into your mind again.. :)
what I wouldn't object to is another flag that strips that white space
from around the fields...
