Hi Folks,

Would like to how to store the response command of a run command


=>setenv addr  'ping 192.172.24.24'

=>setenv ping_resp 'run  addr'

Would to store the outcome of  "run addr" in into a variable and grep for
the characters or string in Uboot.

// Expecting the output as ping response string and parse the outcome with
grep !!
=> echo $ping_respone

Thanks,
Ajit

Dear Ajit Phadnis,

You should ask U-Boot related questions on the U-Boot mailing list [1] 
instead; chances for a helpful reply are much better there than on
lists that do not actually deal with U-Boot.

Unfortunately, there is currently no way (yet) to do that.  When the
hush shell was ported to U-Boot, it was configured and modified for
minimal memory footprint; one of the features that have not been
included is command substitution.

If you really need such a feature, you could port (or have ported) a
more recent version of hush and include this feature.  Today's systems
usually have much more resources than we had at the time when hush was
added, so the additional memory footprint should be acceptable
(especially if you make that option configurable, so those who are not
interested in it or are already tight on memory can opt out).

Further discussions should be done on the U-Boot list [1].
