You can't get the output of a command, that's not implemented. Some
commands work around this in the way that you can pass a variable name
on the commandline and after exit the variable will be filled with the
desired result. the "readline" command is an example for this.

What are you trying to archieve? Often the desire to parse the output of
a command is a sign that you are stretching the barebox scripting
capabilities beyond their limits. Some piece of C code is doing the job
in a much more robust way.
