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)

upsd.users

UPSD.USERS(5)							    NUT Manual							     UPSD.USERS(5)

NAME

       upsd.users - Administrative user definitions for NUT upsd

DESCRIPTION

       Administrative commands such as setting variables and the instant commands are powerful, and access to them needs to be restricted. This
       file defines who may access them, and what is available.

       Each user gets its own section. The fields in that section set the parameters associated with that user's privileges. The section begins
       with the name of the user in brackets, and continues until the next user name in brackets or EOF. These users are independent of
       /etc/passwd.

       Here are some examples to get you started:

	   [admin]
		   password = mypass
		   actions = set
		   actions = fsd
		   instcmds = all

	   [pfy]
		   password = duh
		   instcmds = test.panel.start
		   instcmds = test.panel.stop

	   [monmaster]
		   password = blah
		   upsmon master

	   [monslave]
		   password = abcd
		   upsmon slave

FIELDS

       password
	   Set the password for this user.

       actions
	   Allow the user to do certain things with upsd. To specify multiple actions, use multiple instances of the actions field. Valid actions
	   are:

	   SET
	       change the value of certain variables in the UPS

	   FSD
	       set the forced shutdown flag in the UPS. This is equivalent to an "on battery + low battery" situation for the purposes of
	       monitoring.

       The list of actions is expected to grow in the future.

       instcmds
	   Let a user initiate specific instant commands. Use "ALL" to grant all commands automatically. To specify multiple commands, use
	   multiple instances of the instcmds field. For the full list of what your UPS supports, use "upscmd -l".

	   The cmdvartab file supplied with the distribution contains a list of most of the known command names.

       upsmon
	   Add the necessary actions for a upsmon process to work. This is either set to "master" or "slave".

	   Do not attempt to assign actions to upsmon by hand, as you may miss something important. This method of designating a "upsmon user" was
	   created so internal capabilities could be changed later on without breaking existing installations.
