I've set the cmd.exe prompt to '>' and do the following: >dir /T:W 400000066.err | grep 400000066.err 13.08.2002 14:38 3.061 400000066.err >dir /T:C 400000066.err | grep 400000066.err 13.08.2002 14:33 3.061 400000066.err >dir /T:A 400000066.err | grep 400000066.err 20.06.2007 12:42 3.061 400000066.err >ls -l --full-time --time=atime 400000066.err -rw-r--r-- 1 loewjoha Domänen-Benutzer 3061 2007-06-20 12:51:42.023723400 +0200 400000066.err >ls -l --full-time --time=ctime 400000066.err -rw-r--r-- 1 loewjoha Domänen-Benutzer 3061 2007-06-16 06:05:49.764676100 +0200 400000066.err >ls -l --full-time --time=atime 400000066.err -rw-r--r-- 1 loewjoha Domänen-Benutzer 3061 2007-06-20 12:51:50.227005900 +0200 400000066.err >dir /T:A 400000066.err | grep 400000066.err 20.06.2007 12:42 3.061 400000066.err >dir /T:W 400000066.err | grep 400000066.err 13.08.2002 14:38 3.061 400000066.err >dir /T:C 400000066.err | grep 400000066.err 13.08.2002 14:33 3.061 400000066.err >type 400000066.err > c:\tmp\foobar >dir /T:A 400000066.err | grep 400000066.err 20.06.2007 12:42 3.061 400000066.err >ls --version ls (GNU coreutils) 5.94 Copyright (C) 2006 Free Software Foundation, Inc.

I expected the times displayed by 'dir /T:C' and 'ls -l --time=ctime' to be the same. I'm also confused that 'ls -l --time=atime' apparently modifies the atime of the file. I'm also confused by the fact that 'type 400000066.err' does not change the access time displayed by 'dir' (but that's obviously no Cygwin problem). On the local hard drive everything works as expected: ~/tmp/foo$ ls -l --full-time --time=ctime foo -rw-r--r-- 1 loewjoha Domänen-Benutzer 4 2007-06-20 12:37:32.475250000 +0200 foo ~/tmp/foo$ ls -l --full-time --time=atime foo -rw-r--r-- 1 loewjoha Domänen-Benutzer 4 2007-06-20 12:40:31.631500000 +0200 foo ~/tmp/foo$ ls -l --full-time --time=atime foo -rw-r--r-- 1 loewjoha Domänen-Benutzer 4 2007-06-20 12:40:31.631500000 +0200 foo ~/tmp/foo$ cat foo foo ~/tmp/foo$ ls -l --full-time --time=atime foo -rw-r--r-- 1 loewjoha Domänen-Benutzer 4 2007-06-20 13:07:24.272125000 +0200 foo ~/tmp/foo$ ls -l --full-time --time=ctime foo -rw-r--r-- 1 loewjoha Domänen-Benutzer 4 2007-06-20 12:37:32.475250000 +0200 foo ~/tmp/foo$ I stumbled across this when I tried to use find(1) to find files with an access or modfication time not later than a certain day, but find(1) found rather unexpected files. So, the question I'd actually like to ask is: What is the Right Way (tm) to find all files in a directory tree (on a network drive) that have been accessed (alternatively modified) in the last x days?
