在linux/unix平台的常用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键删除的用户来讲,感受很是别扭,虽然能够经过
java
Ctrl+Backspace
组合键实现删除功能
linux
可经过stty命令修改终端配置来实现Backspace删除功能。以下:oracle

[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,可执行如下命令:ui

[oracle@RHEL5 ~]$ id uid=501(oracle) gid=501(oinstall) groups=501(oinstall),502(dba),503(asadmin) [oracle@RHEL5 ~]$ stty erase ^?
同时可经过stty -a查看全部的终端设置:unix
