ls output interpretation
hi guys, need your help to understand the ls output command
drwxr-xr-x 2 root root 4096 oct 9 2011 xml d - directory rwxr - permission for the owner xr - permission for the group x - permission for others 2 = means what? root = name of the user 4096 = means what? is this a process id or what? thanks. |
2 - links, 4096 - I/O block size. Also see 'stat xml' output.

I am pretty sure that if you use your exact words in google, ie ls output interpretation, at least one of the 4+million replies must have this information.
I would add that some of the information you provided is actually incorrect. |

r-x for the group (NO write permission) r-x for "others" (non-owner nor in the group, which will be most users in this case) These are 3 groups of 3 permission letters, - means NOT allowed 2 link count, you can forget about that (it will always be 2 + the number of SUBdirectories for a directory) root root owner (not user) and group of this directory (cq file) 4096 current size of the file this directory IS. In an ext? fs a directory will always be a multiple of the block size, that is: mkdir allocates a full block and every extension will be allocated that too. In other FS'es this may be different. BTW: directories in ext? will never shrink, so a directory of, say, 16KB with only a single entry IN it is possible, if it used to contain more filenames. |
ehartman, you *could* have posted that answer eight years ago! :D

Now I'm retired I've got much more time to read/post (and have got a few years more experience in several Linux distro's too). So now I just look at a lot of the new postings (and someone did post a new msg in this thread). |
not really, it was already explained several times, even here:
