Examples of menus

• Examples 1

  Here is how to create a trivial embedded menu to illustrate the concept

  $ cat menu1

  " 1 Item 1"
  " 2 Item 2"
  " 3 Item 3"
  " 4 Item 4"
  -
  " 0 Exit"
  

  $ cat menu1.sh

  #!/bin/sh
  
  ENTRY=999
  
  while [ $ENTRY -ne 0 ]; do
    LINE=$(smenu -d -n 0 -l -F -s /"QUIT$" -D o:0 n:2 i:1 d:" " \
                 -E'/^-$/ /' -e '^-$' < menu1)
  
    read ENTRY DUMMY <<< $LINE
  
    case $ENTRY in
      [1-4]) echo "The menu entry $ENTRY has been selected"
             ;;
      0)     ;;
    esac
  done
  
  exit 0

  The result:

  
  
  

• Examples 2

  The same, but horizontal this time. The only difference with the previous example is the smenu call with different options.

  $ cat menu2.sh

  #!/bin/sh
  . . . . . . . . . . . . . . . . . . . . . . . . . . .
  
  LINE=$(smenu -d -n 0 -l -F -D o:0 n:2 i:1 d:" "    \
               -1 Exit -e '^-$' -E'/^-$/ /' -e '^-$' \
             < menu2)
  . . . . . . . . . . . . . . . . . . . . . . . . . . .
  exit 0

  The result:

  
  
  

• Example 3

  Now a matrix version.

  $ cat menu3

  " 1 Item 1" " 2 Item 2"
  " 3 Item 3" " 4 Item 4"
  -
  " 0 Exit"
  

  $ cat menu3.sh

  #!/bin/sh
  . . . . . . . . . . . . . . . . . . . . . . . . . . .
  
  LINE=$(smenu -d -n 0 -c -F -D o:0 n:2 i:1 d:" "    \
               -1 Exit -e '^-$' -E'/^-$/ /' -e '^-$' \
             < menu3)
  . . . . . . . . . . . . . . . . . . . . . . . . . . .
  exit 0

  The result:
