= Linux ls
== último acceso
Cuando estás copiando y el fichero guarda la fecha original de creación, pero quieres ver la fecha de último acceso
<code bash>ls -lu --time=ctime</code>

  * %%--time=atime%% : updated when the file is read
  * %%--time=birth%% : updated when the file contents change. This is the "default" file time in most cases. (mtime)
  * %%--time=ctime%% : updated when the file or its metadata (owner, permissions) change

<code>-u - with -lt: sort by, and show, access time;
         - with -l: show access time and sort by name;
         - otherwise: sort by access time, newest first
</code>
<code>Valid arguments are:
  - ‘atime’, ‘access’, ‘use’
  - ‘ctime’, ‘status’
  - ‘birth’, ‘creation’
Try 'ls --help' for more information.</code>
