1、可以使用echo $SHELL来查看当前使用的shell
alloy@alloy:~$ echo $SHELL
/bin/bash
alloy@alloy:~$ ls -al /bin/sh
lrwxrwxrwx 1 root root 4 3月 15 10:13 /bin/sh -> dash
2、通过对/etc/shells的查看可以看到当前系统中安装的shell
alloy@alloy:~$ cat /etc/shells
# /etc/shells: valid login shells
/bin/sh
/bin/dash
/bin/bash
/bin/rbash
3、使用chsh可以在shell之间进行切换
alloy@raspberrypi:~/linuxshell/chapter9$ chsh
Password:
Changing the login shell for alloy
Enter the new value, or press ENTER for the default
Login Shell [/bin/bash]: /bin/dash
alloy@raspberrypi:~/linuxshell/chapter9$ echo $SHELL
/bin/bash
alloy@raspberrypi:~/linuxshell/chapter9$ chsh
Password:
