Hi,

I have a problem to develop a script that sort files by access time.

I've tried the command ls -ltu or stat -c "%x %n" *, but the problem is
that when i'm launching the script, the date of last access is update
with the time of the script.

Do you have an idea for this problem ?

Thanks a lot.

The atime does not change by an ls or stat command.
ls -1tu
should work ok.

[...]

Maybe the OP did a

ls -ltu *

in which case the atime of the directories where updated as
their content was read.

ls -ltu

or

ls -ltud -- *

should not have the problem.

Hi,

thanks for your answers.

the problem is when I'm doing ls -ltu or stat command the access time
is modified at the time the command is done.

Is it possible to have access to tha access time information of a file
without modify it ?

Thanks a lot,

Yannick.

As has been said, if you compare ordinary files:
"The atime does not change by an ls or stat command."

If in your case that's different you have to provide more information
about your environment, and show what you've exactly done and what
exactly the results have been.

And, BTW, don't top-post.

When I saw his first post, my thought was that one of the files he's
listing is the script itself. Executing the script will indeed update
the atime of the script -- the shell has to read the script to execute
it.

Hi,

The script is done for cygwin environement. It can explain why the
access-time is update.

No, that doesn't, per se, explain anything.
'ls -ltu' works for me with bash on Cygwin as expected.

To repeat what I said: "[...] and show what you've exactly done and
what exactly the results have been."

It might matter which version of Windows and which filesystem (FAT or
NTFS) is being used.
