> No, the point is you want to test not only for Darwin, but for Darwin
version 10.6, as opposed to 10.5 or 10.4. {{{uname -r}}} should return
strings like 10.4.0, 9.3.1, and 8.8.0, respectively, for these (I think).
(The last parts of the string, like 4.0 or 3.1 or 8.0, are the minor
version numbers, which I don't think we care about.)

regular expression match to return the digits found before the first
period.) Then you do something like

Just for the record:
The easiest (and by the way more efficient and less error-prone) way to
test for e.g. Darwin 8 / MacOS X 10.4 / Tiger is to use the (Bourne)
shell's built-in pattern matching:
{{{
#!sh
case "$UNAME" in # set in sage-env
Darwin)
case "`uname -r`" in # quotes not mandatory
8*) # Tiger / 10.4
...
;;
9*) # Leopard / 10.5
...
;;
10*) # Snow Leopard / 10.6
...
;;
*) # other, "default"
...
esac
# add other OSs like Linux here if appropriate
esac
}}}
Or, if you want to use `sed` or `tr`, something like:
{{{
#!sh
os_with_ver=`uname -sr | sed -e 's/ /-/g'` # order of options to 'uname'
doesn't matter
os_with_ver_and_arch=`uname -srm | tr ' ' '-'` # using the simpler
'tr'(anslate) command
case $os_with_ver in
Darwin-8*) # Tiger / Darwin 8 / MacOS X 10.4
...
;;
...
esac
# More specific:
case $os_with_ver_and_arch in
Darwin-8*-ppc) # Tiger / Darwin 8 / MacOS X 10.4 on PPC (32-bit)
...
;;
Darwin-9*-ppc64) # Leopard / Darwin 9 / MacOS X 10.5 on PPC (64-bit)
...
;;
Linux-*-x86_64|Linux-*-ia64) # Any 64-bit Linux version on Intel
...
;;
Linux-*-i[3456]86) # Any 32-bit Linux version on Intel
...
;;
...
esac
}}}
