In the Linux/unix platform often use scanf from the keyboard to get characters, output characters after pressing backspace key to delete, will appear ^h, which is accustomed to the deletion by the BACKSPACE key users, feel very awkward, although you can by CTRL + Backspace key combination for delete function

The terminal configuration can be modified by the Stty command to implement the BACKSPACE removal function. As follows:

QUOTE:

[[email protected] ~]$ ID

uid=501 (Oracle) gid=501 (oinstall) groups=501 (Oinstall), 502 (DBA), 503 (asadmin)

[Email protected] ~]$ Stty erase ^h

To restore the Ctrl+backspace Combo key removal feature, execute the following command:

QUOTE:

[[email protected] ~]$ ID

uid=501 (Oracle) gid=501 (oinstall) groups=501 (Oinstall), 502 (DBA), 503 (asadmin)

[Email protected] ~]$ Stty erase ^?

All terminal settings can also be viewed via stty-a:
