What are the column heading for this "-rwxr-xr-x 1 root root 920788 Mar 28 2013 bash" when I do "ls -l" in the Ubuntu terminal

Question

I executed the command "ls -l" in the ubuntu terminal, I understand the "ls -l" is the long listing in ubuntu, but I don't understand the columns for example: (This was the first line)

-rwxr-xr-x  1   root    root    920788  Mar 28 2013 bash

How would I find out the column headings for the above?

Answer 1

The columns are :

• Permissions (owner, group. all)
• Links
• Owner
• Group
• Size in bytes
• Time of last modification
• Name

So "-rwxr-xr-x 1 root root 920788 Mar 28 2013 bash" means:

• user root has permissions rwx (read, write, execute).
• group root has permissions r-x (read and execute).
• Everybody has permissions r-x (read and execute).
• The file has only 1 hard link.
• The owner is root.
• The group is root.
• Size is 920788 bytes.
• Last modified in March 28, 2013.
• The file name is bash.
