1.查看linux支持的shell
[wirelessgroup1@jxq-wn-wap21 etc]$ cat /etc/shells /bin/sh /bin/bash /sbin/nologin /bin/tcsh /bin/csh /bin/zsh /bin/ksh
2.切换shell
每个shell都有自己典型的外观
[wirelessgroup1@jxq-wn-wap21 etc]$ sh sh-3.2$
sh-3.2$ bash [wirelessgroup1@jxq-wn-wap21 etc]$
3.查看用户默认的shell
[wirelessgroup1@jxq-wn-wap21 etc]$ cat /etc/passwd root:x:0:0:root:/root:/bin/bash wireless_group4:x:533:533::/home/wireless_group4:/bin/bash
