oracle - SQL*PLUS Linux Client not backspacing upon linewrap -
first database class new oracle , sql*plus. when typing commands @ prompt if reach edge of terminal window , wrap next line unable return previous line using backspace.
an example (_ indicates position of cursor block):
sql> !od -c <<< "test aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaathisisat est"_ if terminal wraps able backspace here:
sql> !od -c <<< "test aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaathisisat _ once reach point no matter method use backspace, prompt not return previous line.
strangely can resize terminal window bring cursor block previous line , continue backspacing not work.
passing input od standard wrapped line comes out fine:
0000000 t e s t 0000020 * 0000120 t h s s t e s t \n however if change terminal size , cursor block stuck no matter positioned , execute command receive error:
sp2-0042: unknown command """ -rest of line ignored. inspecting output next /n isn't inserted until after sql> prompt appears again:
0000000 s q l > ! o d - c < < < 0000010 " j k s d h f k j d s h s d h 0000020 f k s d h f s d f s d f 0000030 d s f d f d s f d s 0000040 d s d s f d s d f d f 0000050 " s 0000060 p 2 - 0 0 4 2 : u n k n o w n 0000070 c o m m n d " " " - r 0000080 e s t o f l n e g n o 0000090 r e d . 00000a0 00000b0 s q 00000c0 l > \n this behavior not present on windows able backspace previous line wrapped 1 when using sql*plus client in cmd.
