Redhat cannot find the rpm command Solution

Redhat cannot find the rpm command solution. When I want to use the rmp command, the system prompts command not found, so I wonder, is it because the release version I downloaded is too low, I did not find any solution on the Internet, I used find/rpm and found that the original rpm was in/bin/rpm, and then I could execute www.2cto.com permanent solution to set environment variables, add/sbin to path. vi/etc/profile. Add export PATH = "$ PATH:/bin" at the end. Save the file and log out of the computer.
