POSIX Shell (e.g. bash, ksh and others):
====
for secondsin in 1 59 61 100 101 10000; do
temp=$secondsin;
h=$(( temp / 3600 ));
if test $h -gt 0; then
temp=$(( temp - h * 3600 ));
fi
m=$(( temp / 60 ));
s=$(( temp % 60 ));
printf "%i second(s) are %i hours, %i minutes and %i seconds\n" \
$secondsin $h $m $s;
done
====
Adjust the output-format as you like, you got the neccessary numbers
neatly seperated in $h, $m and $s.
See "Arithmetic Expansion" or something like that in the manpage of
your shell.
Tested with bash 2.03 (in bash and sh mode), pdksh 5.2 and zsh 3.0.
pdksh and zsh seem to have no 'printf' builtin (/usr/bin/printf is
used), but that should not be a problem.
Any questions?
HTH,
