Full Discussion: Creating an array out of users: shell script
Operating Systems BSD Creating an array out of users: shell script Post 302501974 by Scott on Sunday 6th of March 2011 06:07:01 AM

One option:

Code:
USERS=("" $(awk -F: '{print $1}' /etc/passwd))

echo ${USERS[@]} | awk '{print ++C ") " $1}' RS=" "

printf "Enter a number:  "
read OPTION

echo You chose ${USERS[$OPTION]}

Or you could use select, for example:
Code:
USERS=("" $(awk -F: '{print $1}' /etc/passwd))

PS3="Select a user: "
select USER in ${USERS[@]}; do
 break
done

echo You chose $USER

(you need to modify the awk to remove blank lines, comments and system users)

fvwm-themes-menuapp

FVWM-THEMES-MENUAPP(1)						   FVWM Utility 					    FVWM-THEMES-MENUAPP(1)

NAME

       fvwm-themes-menuapp - fvwm-themes menus utility

SYNOPSIS

       fvwm-themes-menuapp --build-menu or --com-mode or--help or --version [ --site] [ --menu-files [file1,file2,...] ] [ --remove-popup] [
       --com-name name]

DESCRIPTION

       This script is not a user script. It is used by Fvwm-Themes to do differrent task concerning menu and other related things.  This scripts
       can do the following:

       Parse and rebuild FVWM configuration files to build a clean menu from them: application not in the path are removed, certain unuseful sub
       menus and separator are removed (--build-menus option).

       It can work in a locked way and communicate (via fvwm-themes-com) with FvwmScript-Menus or any other programs (--com-mode option). See
       below for the list of query that you can ask to fvwm-themes-menuapp via fvwm-themes-com.

       Plan for the future: use an application data base and parse and build (Mini)Icon Styles.

OPTIONS

       You must use (only) one of the following four options:

       --help	 - show the help and exit

       --version - show the version and exit

       --build-menus - Cause fvwm-themes-menuapp to build clean menus.

       --com-mode Run fvwm-themes-menuapp under the "communication mode".

       --menu-files [file1,file2,...] - files which are read and written by fvwm-themes-menuapp. By default, fvwm-themes-menuapp will read
       $FT_DATADIR/themes/default/menus-programs with the --site option.  Without the --site option fvwm-themes-menuapp will read menus-programs
       and menus-extra	(if found) in the fvwm-themes personal dir: $FVWM_USERDIR/themes/personal.  If menus-programs is not found in this direc-
       tory the site's menus-programs file is used (the one under $FT_DATADIR). Moreover, if menus-extra is not found, a virtual such file is cre-
       ated so that the "personal" menus can be created (MenuFvwmPersonal) in it.

       --site - Change the default for the --menu-files option.

       --remove-popup - Remove the sub menu popup that popup empty menu (only useful with --build-menus). In fact only certain sub menu popup are
       removed.

       --com-name name - use name as name for communication with fvwm-themes-com.  By default, "appmenu" is used, but you should use  "app-
       menu-pid" as name where pid is the pid of the program that want to talk to fvwm-themes-menuapp so that fvwm-themes-menuapp can exit if this
       program exit and so that fvwm-themes-menuapp can kill the program if an internal error happen in fvwm-themes-menuapp. On the other hand, if
       you want to talk with fvwm-themes-menuapp in, say, a terminal you must not give an name as "menuapp-an_integer" as name.

	       fvwm-themes-menuapp --com-mode [--com-name=menuapp-pid ...]

       Then use fvwm-themes-com as:

	       fvwm-themes-com --name menuapp[-pid] [--lock-and-get] --message="Command"
