SELECT and wrapping to next column
Hi all,

Am trying to write a menu driven script using SELECT and if I have more than 4 options, it wraps to the next column. That is if I have 6 choices, items 5 and 6 are in the second column.

Is there any settings that control this behavior or is it due to some stty settings?

stty -a output as below:

Code:
speed 38400 baud; rows 38; columns 150; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W;
lnext = ^V; flush = ^O; min = 1; time = 0;

It does not wrap to the second column using KSH88 but on PD KSH v5.2.14 99/07/13.2, it does Smilie... Frustrating that I have three different KSH versions ... aaarrgghhh Smilie

Let your lists be vertical and limitless using '\'
Code:
$ echo 1\
>  2
1 2
$

Don't use select; it doesn't give you much control.

True, I only use "for <var> in <list> ; do ... done" and even more often, being more robust and low latency, (parens needed in BASH) "(while read <vars> ; do ... done)", either with a pipe "echo <list>|tr ' ' '\12'|...." or a Here Document (great for managing lists one item per line) "... <<-!\n\tItem1\n\tItem2\n...\n!\n".
