Great idea to use bc(1) ;-) It doesn't really parse sticky, suid or
sgid bits, but it's smaller than the awk version. The following did
the trick nicely (but is too ``complicated'', and I'd still like
having a tool that allows userland to call stat/fstat(2):
hades+charon:/tmp$ cat foo.sh
#!/bin/sh
echo 'ibase=2;obase=8;' \
` ls -ld "$1" | \
cut -c2-10 | \
sed -e '/^..[sS]/ s/^.*$/&+100000000000/' \
-e '/^.....[sS]/ s/^.*$/&+10000000000/' \
-e '/^........[tT]/ s/^.*$/&+1000000000/' | \
sed -e 's/[st]/x/g' -e 's/ST/-/g' | \
sed -e 's/[rwx]/1/g' | \
sed -e 's/[^1+]/0/g' ` | bc
% sh foo.sh /tmp
hades+charon:/tmp$ sh foo.sh /tmp
