stty erase - backspace

 Può accedere che  il pulsante "backspace" non funzioni correttamente su un terminale linux.

Ad esempio mi collego ad sqlplus e premendo backspace compare ^H come di seguito.

Connected to:

Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> selece^Ht   ^H^H^H^H^H^H^H^H

Si può rispovere usando Shift+Backspace oppure cambiano il comando di "erase"

$ stty -a

speed 38400 baud; rows 56; columns 128; line = 0;

intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S;

susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;

Con questo comando  stty erase ^H si imposta il corretto funzionamento del backspace.
