Hi. When you ssh in you see something like this:
BusyBox v1.33.0 (2021-03-04 02:03:13 +07) built-in shell (ash)

Or at top of GUI:
Firmware: DD-WRT v3.0-r45891 std (03/04/21)

Or uname -a
Linux DD-WRT 4.9.258 #2465 SMP Thu Mar 4 02:00:54 +07 2021 armv7l DD-WRT

I was wondering if we can get it from the command line. Just -> 3/4/21 which is my current.

With:
nvram show 2>&1 | grep -m1 "os_version="
I can get:
os_version=45891

I tried:
x=$(busybox /bin/ash -v)
but it hangs...

Was thinking -> x=$(uname -a)
Then sed,grep,awk it and translate 'Mar' to '03'
but that is a bit much

Is there any nvram var or something I could use to get the date part?
Worked on it but could not get it so thought I'd ask here.

Thanks..

Answering my own post. I got it and it was right in front of me. When you SSH in say with Putty at the top it says:
Pre-authentication banner message from server:
| DD-WRT v3.0-r45891 std (c) 2021 NewMedia-NET GmbH
| Release: 03/04/21
| Board: Linksys WRT3200ACM

That info comes from:
/tmp/loginprompt

So:
the_date=$(cat /tmp/loginprompt | sed -n '2 p' | cut -d ' ' -f 2 | tr -s '/' '-')

echo $the_date returns:
03-04-21

Maybe someone will expand on it. Still don't know where DD-WRT gets it. I figure it must set it up internally somehow.

The firmware date is set during the compile and build process, if I am not mistaken.

Thank you for the responses. Understood now.
