For what it is worth, the POSIX test on Solaris has things you would expect.
Most of my scripts on Solaris will exec KSH if not running in a POSIX she’ll,
but for minor thing like this you could consider conditionally defining a
function to override the built in:
$$ /bin/sh
$$ if [ www -nt jar_resigning ]; then echo newer ; else echo older ; fi
test: unknown operator -nt
$$ if test www -nt jar_resigning; then echo newer ; else echo older ; fi
test: unknown operator -nt
$$ [ SunOS = `uname -s` ] && [ xy != `IFS=''; set x y; echo "$*"` ] && test ()
{ env -i PATH=/usr/xpg4/bin:$PATH test "$@" ; }
$$ if test www -nt jar_resigning; then echo newer ; else echo older ; fi
older
$$
Ignore any stupid email line-wrapping. Sending from my phone. Function above
should be all on one line.
With other shells on solaris you can put a backslash in front of the command to
get the actual command rather than the built-in, but that doesn’t work for
Solaris /bin/sh, in its misfit glory.
The above first tests that it is Solaris, then whether the /bin/sh is the
broken one (among its many bugs, it doesn’t handle IFS correctly), before
overriding the test built-in.
