====== Display numeric permissions using ls ======
Create an alias for the LS command.
<code bash>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}'</code>

Output should be with the nummeric permissions at the beginning of each row:
<code bash>
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}'
