This patch fixes a tiny bug in the command line editing of the RTEMS shell. Typing CTRL-U in the shell should remove all characters left of the cursor. After pressing CTRL-U, the current implementation does wrongly place the cursor at the end of the line instead at its beginning. To reproduce the bug, start the shell and type 'abc123' (no <RETURN>): > ~/src/rtems $ qemu-system-arm -net none -nographic -M realview-pbx-a9 \ -m 256M -kernel build/arm/realview_pbx_a9_qemu/testsuites/libtests/dl10.exe > *** BEGIN OF TEST libdl (RTL) 10 *** > *** TEST VERSION: 6.0.0.d9bdf166644f612dd628fe4951c12c6f8e94ba5f > *** TEST STATE: USER_INPUT > *** TEST BUILD: RTEMS_DEBUG RTEMS_NETWORKING RTEMS_POSIX_API RTEMS_SMP > *** TEST TOOLS: 10.2.1 20200904 \ (RTEMS 6, RSB 31f936a7b74d60bda609a9960c6e1a705ba54974, Newlib a0d7982) > RTL (libdl) commands: dl, rtl > > RTEMS Shell on /dev/foobar. Use 'help' to list commands. > SHLL [/] # abc123 Then move the cursor onto the '1' by hitting three times the <ARROW-LEFT> key. Next type <CTRL>-U: > SHLL [/] # 123 Note that the cursor is at the end of the line (after '3') instead of correctly at the beginning (on the '1'), now. Continuing typing 'echo ' incorrectly results in the output: > SHLL [/] # 123echo 123 The patch changes this behavior so that the cursor in the second last step will be on the '1' and typing 'echo ' will then correctly reflected as: > SHLL [/] # echo 123 Close #4096.
