On the linux server after a new user, ssh remote login with the new user will find some garbled up and down keys F1-F12 and so on. In fact, Linux is a server-side problem, because the new user uses a different shell
Open the target file
vim /etc/passwd 
This is a new indicator of the user's shell sh
The root user is using the bash
In addition to the problems garbled still have no command prompt login user name and host name, not the current path name
Simple process, so that the new user / ect / profile and /etc/bash.bashrc configuration [there should be follow-up article about these two files]
/ bin / SH read / bin / bash
Then use ssh to log back on it, if you do not want to re-visit
#立即生效
source /etc/passwd ----------------
