cmd = "/usr/bin/sudo /root/" + " 1>&2"
result = system(cmd)
logger.error "result = #{result}" **************************************
I got result value is false,but when I run this code in the test.rb script with same code,I got true,I don't know why.It is totally same code. script just echo "run this script"
