You can even add a "-h" option to the ls command to print sizes in human readable format :-)

Thanks @sweetdub - very useful :)

@sweetdub : I use a tiny function to display the numerical chmod permissions when I do a ls. But I lost my colors. How I can keep my colors? Maybe you know :)

try this one, it's works for me :)
alias l="ls -lah --color | 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}'"

thanks @sweetdub - brilliant, but doesn't work on my mac lion osx : "illegal options"
Anyway, doesn't matter ;)
