Try linux command chsh.
试试 linux 命令chsh。
The detailed command is chsh -s /bin/bash.
It will prompt you to enter your password.
Your default login shell is /bin/bashnow. You must log out and log back in to see this change.
详细命令是chsh -s /bin/bash. 它会提示您输入密码。您的默认登录 shell/bin/bash现在是。您必须注销并重新登录才能看到此更改。
The following is quoted from man page:
以下引用自手册页：
The chsh command changes the user login shell. This determines the name of the users initial login command. A normal user may only change the login shell for her own account, the superuser may change the login shell for any account
chsh 命令更改用户登录 shell。这决定了用户初始登录命令的名称。普通用户只能修改自己账户的登录shell，超级用户可以修改任何账户的登录shell
This command will change the default login shell permanently.
此命令将永久更改默认登录 shell。
Note: If your user account is remote such as on Kerberos authentication (e.g. Enterprise RHEL) then you will not be able to use chsh.
注意：如果您的用户帐户是远程的，例如 Kerberos 身份验证（例如 Enterprise RHEL），那么您将无法使用chsh.

You should have a 'skeleton' somewhere in /etc, probably /etc/skeleton, or check the default settings, probably /etc/defaultor something. Those are scripts that define standard environment variables getting set during a login.
您应该在/etc，可能 中的某处有一个“骨架” /etc/skeleton，或者检查默认设置，可能/etc/default或其他。这些是定义在登录期间设置的标准环境变量的脚本。
If it is just for your own account: check the (hidden) file ~/.profileand ~/.login. Or generate them, if they don't exist. These are also evaluated by the login process.
如果仅用于您自己的帐户：检查（隐藏）文件~/.profile和~/.login. 或者生成它们，如果它们不存在。这些也由登录过程评估。

You can change the passwd file directly for the particular user or use the below command
您可以直接为特定用户更改密码文件或使用以下命令
chsh -s /usr/local/bin/bash username
Then log out and log in
然后注销并登录
