list directory contents |
-a Write out all directory entries, including those whose names begin with a period ( '.' ). Entries beginning with a period shall not be written out unless explicitly referenced, the -a option is supplied, or an implementation-defined condition shall cause them to be written. |
-r Reverse the order of the sort to get reverse collating sequence or oldest first. |
-l (The letter ell.) Do not follow symbolic links named as operands unless the -H or -L options are specified. Write out in long format (see the STDOUT section). When -l (ell) is specified, -1 (one) shall be assumed. |
-t Sort with the primary key being time modified (most recently modified first) and the secondary key being filename in the collating sequence. |
