[SOLVED] I need help with a CLI menu shell script

BobTruck · 11-11-2009, 10:41 AM

I am trying to write a shell script that displays a menu with 22 options of commands. I would like to have an option to display another menu of more options, but I can't get it to function properly. I am using a while loop with case for the options. Any help would be greatly appreciated.

Code:

#!/sbin/sh

DisplayMenuA()
{
  echo ""
  echo ""
  echo "================================================================================"
  echo "================================= All Scripts =================================="
  echo "================================================================================"

There is not an error, just a lack of function. I would like to display the first menu, then if selected the second and then the third. I have been able to display the first, but then I am only able to go the second or third from the first. If I try to go to the third menu from the second menu, it goes to the Wait() and then returns to the first menu. I hope this helps clarify my issue.

Thanks lewc, I will do a rewrite and give it a try.

bash has a builtin command "select" which you may find useful instead of coding it up yourself. From man bash or "help select"

Code:

$ help select
select: select NAME [in WORDS ... ;] do COMMANDS; done
    The WORDS are expanded, generating a list of words.  The
    set of expanded words is printed on the standard error, each
    preceded by a number.  If `in WORDS' is not present, `in "$@"'
    is assumed.  The PS3 prompt is then displayed and a line read
    from the standard input.  If the line consists of the number
    corresponding to one of the displayed words, then NAME is set
    to that word.  If the line is empty, WORDS and the prompt are
    redisplayed.  If EOF is read, the command completes.  Any other
    value read causes NAME to be set to null.  The line read is saved
    in the variable REPLY.  COMMANDS are executed after each selection
    until a break command is executed.

lewc, I started the rewrite but my coworkers thought that a multilevel menu was not simple enough. I ended up rewriting the menu to display 3 rows with all of the options for the user. I appreciate the information and advise you gave me and I will use it in my scripts at home. I guess that sometimes simple is better (for the end user). Thanks also to lwasserm for the post about using select.

You might also consider using the "dialog" program to generate nice, colored ncurses menus.
