[U-Boot] common, hush: bug (or feature?) with exit

Hello,

I try the following script in u-boot --------------------------------------------------------------------- setenv error 'if true; then echo **** ERROR **** exit; fi'

setenv foo echo "****************This should not be printed" setenv loadubi

setenv updfs 'if true; then echo; echo ========== Updating rootfs ==========; echo; if run loadubi; then echo ***************loadubi else; run error fi fi'

echo ========== start ==========

run updfs run foo ---------------------------------------------------------------------

running it with:

bpp3> source 80008000 ## Executing script at 80008000 ========== start ==========

========== Updating rootfs ==========

## Error: "loadubi" not defined **** ERROR **** ****************This should not be printed bpp3>

I expected that the script (if loadubi is not defined) exits after the "echo **** ERROR ****", and do not print the line "****************This should not be printed"

Is this a feature or a bug in hush shell?

Thanks for any hints!

bye, Heiko
