[982]% perl vers.pl 4.09 4.08.1
zsh: exit 1 perl vers.pl 4.09 4.08.1
[983]%
BTW:
Using perl in autoconf... What next? Slicing bread with the
Swiss Army Chainsaw(tm)? heart surgery? splitting atom cores? B)
<quote>
The `configure' script [...] should not use any utilities directly
except these:
cat cmp cp diff echo egrep expr false grep install-info
ln ls mkdir mv pwd rm rmdir sed sleep sort tar test touch true
</quote>
sequence_compare () {
# usage:
# ``IFS="." sequence_compare 1.2.3 <-lt|-le|-eq|-ge|-gt> 4.5''
# - no *sh- or system-specific features
# - relies on IFS as field separator
a="$1"; op="$2"; b="$3";
while test -n "$a$b"
do
set -- $a; h1="$1"; shift 2>/dev/null; a="$*"
set -- $b; h2="$1"; shift 2>/dev/null; b="$*"
test -n "$h1" || h1=0; test -n "$h2" || h2=0
test ${h1} -eq ${h2} || break
done
test ${h1} "$op" ${h2}
}
Of course, for autoconf functions are VERBOTEN, and therefore the
original $IFS has to be saved & later restored...
Cheers,
Michael
