在linux/unix平台的经常使用scanf从键盘获取字符,输出字符后按Backspace键删除时,会出现^H,这对习惯了按Backspace键删除的用户来说,感觉非常别扭,虽然可以通过Ctrl+Backspace组合键实现删除功能
可通过stty命令修改终端配置来实现Backspace删除功能。如下:
QUOTE:
[oracle@RHEL5 ~]$ id
uid=501(oracle) gid=501(oinstall) groups=501(oinstall),502(dba),503(asadmin)
[oracle@RHEL5 ~]$ stty erase ^h
若要恢复Ctrl+Backspace组合键删除功能,可执行以下命令:
QUOTE:
[oracle@RHEL5 ~]$ id
uid=501(oracle) gid=501(oinstall) groups=501(oinstall),502(dba),503(asadmin)
[oracle@RHEL5 ~]$ stty erase ^?
同时可通过stty -a查看所有的终端设置:
