UNIX for Dummies Questions & Answers

when i list the content of a directory
date informations are also listed (ls -ltr)
for included files and directories.

for example: i see the date Jun 29 14:43
for one of the included directory,
but when i look into the files contained in
this directory i cannot see any file with this date
(including the hidden files)

how can this happen?

From man ls,

.. ls -l option gives a long listing of files along with mode, ACL indication, number of links, owner, group etc.. The date/time you see there is the time of last modification of the file / directory. So, isn't it logical if any file(s) in that directory do not have the same modification date as the directory itself?

U many try copying an old directory to another location and observe the timestamps of this new directory and its contents...hope this helps.

Goodluck,
