Hi
just got a users report about different behaviour between two
versions of the ksh. From the report of Tony Ernst <[email protected]>:
The following scripts will ask "Which operation would you like to do:"
Then, no matter what you enter, they will ask "Re-enter selection:"
At this point, if you enter a character and then a backspace, the cursor moves
back to the beginning of the line, instead of returning to the end of the
prompt like it should. This failure only happens on sles11. It worked fine on
sles10.
The failure doesn't happen with this script:
--------
#!/bin/ksh
print " Which operation would you like to do: \c"
read inp
print " Re-enter selection: \c"
read inp
print " Re-enter selection: \c"
read inp
--------
But it does fail if the 'read' is inside a loop:
--------
#!/bin/ksh
print " Which operation would you like to do: \c"
while [ true ]
do
read inp
print " Re-enter selection: \c"
done
--------
or called from a recursive function:
--------
#!/bin/ksh
function ov_get_input
{
read inp
print " Re-enter selection: \c"
ov_get_input
return 0
}
print " Which operation would you like to do: \c"
ov_get_input
--------
I've tested this out and it should be noted that this does not depend
on multi byte character locale as this also happens within ISO-8859-1
and UTF-8 ...
