space delimited list of users in a variable
Greetings
So glad I found this forum!
I need to get a list of users in a variable so I can use "for" to iterate through them in a bash script.
I know this does not work, but I need to do something like this:
myusers=(cat /etc/passwd | cut -f1 -d )
for myuser in $myusers
do
some work on the user in $myuser
done
google failed to return an answer.
thanks in advance
Steve.

removeuser
removeuser(8) System Manager's Manual removeuser(8)
NAME
removeuser - Deletes user accounts interactively
SYNOPSIS
/usr/sbin/removeuser
DESCRIPTION
Security Note
If you have enhanced security installed on your system, you should use the dxaccounts command to remove users. See the Security manual and
the dxaccounts(8) reference page for more information.
The removeuser command is an interactive command for deleting user accounts from your system. It also gives the option of deleting the
user's home directory, files and mail. The command prompts you for specific information and informs you of its activity and error condi-
tions.
The removeuser command invokes /usr/sbin/userdel to delete the user account information from /etc/passwd and the hashed password database
(if present).
Only the superuser can execute this command.
The command performs the following tasks: Asks for a login name for the user to be deleted. Enter the login name. If this entry does not
exist in the /etc/passwd file, the command informs you of this and exits. If the entry does exist, the command continues. Displays the
entry for the user from the /etc/passwd file and asks if this is the entry you want to delete. If the answer to this query is no, the com-
mand indicates that the user was not deleted and then exits. If the answer to this query is yes, the command deletes the user's entry from
the /etc/passwd file and any occurrences of the user from the /etc/group file. It then states that the user was deleted. Searches several
administrative directories and files for occurrences of the user and informs you if they exist. If so, it suggests that you may want to
delete these occurrences when the command is finished. If no occurrences of the user are found in these directories and files, the command
indicates so. Asks if you want to delete the home directory, all subdirectories, and all mail files for the user. If the answer to this
query is no, the command indicates that the user's home directory was not deleted and then exits. If the answer to this query is yes, the
command continues.
As a precaution, the command reminds you that you should have backed up the files for the user before removing them if you do not
want to lose them. It then asks if you are sure that you want to delete the files for this user. If the answer to this query is
no, the command indicates that the user's home directory was not deleted and then exits. If the answer to this query is yes, the
command states that it is removing the user's home directory, its contents and the user's mail file. It then deletes these items.
At this point, the command ends.
NOTES
Users are advised to migrate to the /usr/sbin/userdel utility or the dxaccounts utility as this command may be removed in a future version
of the operating system.
EXAMPLES
Enter a login name to be removed or <Return> to exit: john This is the entry for (john) in the /etc/passwd file:
john:VSh6/xbMqPDcY:5006:15:sdf:/usr/users/john:
Is this the entry you want to delete (y/n)? y Working ... Entry for (john) removed. Searching relevant directories and files for (john)
... None found. Do you want to remove the home directory, all subdirectories, files, and mail for (john) (y/n)? y The files for (john)
will be lost if not backed up. Are you sure you want to remove these files (y/n)? y Deleting /usr/users/john Deleting
/usr/spool/mail/john
