Hello,

I am working on Linux-2.6 kernel

I want to configure command date such that whenever I change date and time using date command the changes should get reflected in hardware clock which can be checked by hwclock command.

I am using Busybox-1.21.0.

the command date has no such option, but there is another command named hwclock.

Ya you are write hwclock is there.

I want to customise command Date such that when ever i enter date to sets time to system and custom is set time in hwclock

this is my question

That is not a question but a statement. If you want to modify the functionality of a command you need to download its source and implement the new features.

Ther source in this case is busybox.

http://www.ibm.com/developerworks/li...ary/l-busybox/

I'm more of a proponent of writing a script and then using the commands for their intended purpose. Everytime I modify a binary command my use of it is highly specific as this would be, so I stopped because there's really a different, and supported way to accomplish that goal.

Further, my tendency in many cases is to remove a particular Busybox link and put in the true binary for a command, because I had found that the Busybox alternative didn't fully support options I needed/wanted to use. Grep and find are big candidates for replacement in my book. Busybox has gotten better over the years.

Thank you every one,

I have used the Sytem API to do this
