Hi Debian users

I didn't found information about "/usr/bin/size" via Google. I don't
understand the purpose of this command.

For school I need to complete some exercises.

$ size /bin/ls
   text    data     bss     dec     hex filename
  75375     928    1104   77407   12e5f /bin/ls

What does this Output mean? What are the sections "text", "data" and "bss"?

Why the "dec" size differ from "ls" output?

$ ls -al /bin/ls
- -rwxr-xr-x 1 root root 78004 2007-09-29 14:51 /bin/ls

cheers
Simon
