[ WISH ] Show file permissions in octal format

[cig0]

Hello all,
Longtime ls++ fan here.
If you guys ever have the time I think it would be cool to add octal capabilities to the ls listing like I use with the traditional GNU ls:

...

To achieve this, I use this beautiful awk command - kudos to its creator:

awk '{k=0;for(i=0;i<=8;i++)k+=((substr($1,i+2,1)~/[rwx]/)*2^(8-i));if(k)printf(" %0o ",k);print}'

Like:

/usr/bin/ls -lha --group-directories-first --color -F | awk '{k=0;for(i=0;i<=8;i++)k+=((substr($1,i+2,1)~/[rwx]/)*2^(8-i));if(k)printf(" %0o ",k);print}'

Cheers
