Hi:

Can some of the experienced folks share how the following
_expression_ is evaluated

[ -e "${DESTDIR}/etc/$${f##*/}" ] || \

It removes everything in $f, upto the last "/" (forward slash):

db ~> f=/tmp/test                                   [s002@daniel-bonds-mac-pro]

db ~> echo ${f##*/}                                 [s002@daniel-bonds-mac-pro]

test

so it  checks if "${DESTDIR}/etc/<file>" exists

i'm keen to understand how the "amd64 -> x86_64" moniker is fed
to this _expression_ and evaluated.

For details, please see line 153 in /usr/src/etc/Makefile at
http://gitweb.dragonflybsd.org/dragonfly.git/blob/HEAD:/etc/Makefile

Any pointers ?


thanks
Saifi.

Cheers,

danny.
