[Adarsh Babu Kalepalli]

Hi,

u-boot Version: 2019.10
H/W Board : Beaglebone Black

'env exists env_varName' does not display the existance
status of 'env_varName' environment variable.

Usage:
env ask name [message] [size] - ask for environment variable
env default [-f] -a - [forcibly] reset default environment
env default [-f] var [...] - [forcibly] reset variable(s) to their default
values
env delete [-f] var [...] - [forcibly] delete variable(s)
env edit name - edit environment variable
env exists name - tests for existence of variable
env export [-t | -b | -c] [-s size] addr [var ...] - export environment
env import [-d] [-t [-r] | -b | -c] addr [size] [var ...] - import
environment
env print [-a | name ...] - print environment
env print -e [name ...] - print UEFI environment
env run var [...] - run commands in an environment variable
env save - save environment
env set -e name [arg ...] - set UEFI variable; unset if 'arg' not specified
env set [-f] name [arg ...]

=> printenv ver
ver=U-Boot 2019.10 (Oct 14 2019 - 00:47:50 -0700)
=> env exists ver

What is the expected Output and where is the result updated??
