Hi,
Backfire 10.03.1 on TP-Link WR-1043ND
use the command touch with option -d to update the last-modified date on the given files

     touch -d '2010-10-10 10:10' test.file

I tried different date formats, but the result is always the same

root@OpenWrt:~# touch -d '2010-10-10 10:10' test.file
[b]touch: invalid option -- d[/b]
BusyBox v1.15.3 (2012-04-11 21:01:29 EEST) multi-call binary

Usage: touch [-c] [-d DATE] FILE [FILE]...

Update the last-modified date on the given FILE[s]

Options:
        -c      Do not create files
        -d DT   Date/time to use

where I'm wrong?
Thank you for your answers.

You're not wrong, its likely that the busybox touch got compiled without support for the -d flag.

jow
thanks for the quick reply,
where I can set this option? how compiled with support the -d flag.
sorry, google did not help me

The "-d" option in "touch" is protected by "CONFIG_DESKTOP" in busybox.

make menuconfig -> Base System -> busybox -> Busybox Settings -> General Configuration -> [*] Enable options for full-blown desktop systems

thank you very much!

just rebuilt the image, the error is gone, but the date (time) modification of the file does not change

root@OpenWrt:~# touch -d '2010-10-10 10:10' test.file
root@OpenWrt:~# ls -l test.file
-rw-r--r--    1 root     root            0 Apr 29 15:01 test.file

what could be the reason?

p.s. maybe this is a bug earlier busybox, in OpenWrt from trunk (with busybox 1.19) I do not have these problems and the  touch works as expected.
