Solve the problem of "^ H" displayed by sqlplus in Linux

In Linux, sqlplus returns the "^ H" solution-general Linux technology-Linux programming and kernel information. The following is a detailed description. Set environment variables:

1) In bash, add stty erase ^ H to. bash_profile.

2) under csh, add stty erase ^ H to. cshrc.

The following is my implementation method today (in bash)

[Root @ testdb ~] # Su-oracle go to the oracle Home Directory, which contains. bash_profile
[Root @ testdb ~] # Vi. bash_profile Add a row

Setty erase ^ H

: Wq save and exit

You can log on to oracle again.
