Create an alias for the LS command.
ls -l | awk '{k=0;for(i=0;i<=8;i++)k+=((substr($1,i+2,1)~/[rwx]/) *2^(8-i));if(k)printf("%0o ",k);print}'
Output should be with the nummeric permissions at the beginning of each row:
adm@lxpssl:/home$ ls -l | awk '{k=0;for(i=0;i<=8;i++)k+=((substr($1,i+2,1)~/[rwx]/) *2^(8-i));if(k)printf("%0o ",k);print}' total 3 755 drwxr-xr-x 2 adm domain users 1024 Mar 22 2016 adm 755 drwxr-xr-x 2 adm1 domain users 1024 Feb 11 2016 adm1 755 drwxr-xr-x 2 adm2 domain users 1024 Apr 11 2016 adm2 adm@lxpssl:/home$
