Linux command terminal prompt displays-bash-4.2# workaround

Yesterday in the configuration of Linux, suddenly found that the root login Xshell terminal prompt shows the-bash-4.2# instead of [email protected] hostname + path display. I don't know why this happened. Today we finally got this problem,
The reason is that several of the configuration files under root/root are missing and the missing files are as follows:
1,. bash_profile
2,. BASHRC
These files are required for each user.
Use the following command to re-copy a copy of the configuration information from the primary default file to the/root directory

-bash-4.2# cp/etc/skel/.bashrc/root/-bash-4.2# cp/etc/skel/.bash_profile/root/

Logout re-link is back to normal.
