我的发言是:
dialog --title Example --menu Select: 0 0 0 1 ABC 2 DEF 3 GHI
我希望选择2是通过缺席(而不是)选择的。 其可能性如何?
Try:
dialog --title Example --default-item 2 --menu Select: 0 0 0 1 ABC 2 DEF 3 GHI
方言——标题是“Example”——default项目2 -menu “当选”25 3 1 “ABC” 2 “DEF” 3 “GHI”
use of ["] for strings is most recommended --default-item is common option provided into dialog utilities for menu box or forms. This will keep selection on 2 option.
