Display usernames and their UIDs

Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:

Write a script that displays all usernames and their UIDs in the following fashion:
name1 uid=999
name2 uid=888
... ...

2. Relevant commands, code, scripts, algorithms:

grep, cut, id, echo, for...do...done

3. The attempts at a solution (include all code and scripts):

I managed to list usernames and UIDs but I can't figure out how to add "uid=" string. I've been coming back to this problem for the last two days but maybe my approach is wrong. Please, help Smilie
Since I don't have a Solaris or Linux on PC, I've tested the code on tutorialspoint/execute_ksh_online.

Code:
#!/bin/bash

sort -nr -t ':' -k3 /etc/passwd | cut -d: -f1,3

4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):

NAME
ldapscripts - Scripts to manage POSIX accounts in your LDAP directory. DESCRIPTION
The ldapscripts are a set of shell (sh) scripts designed to manage POSIX accounts in an OpenLDAP directory. They can be used as standalone tools or within Samba 3.x's smb.conf file. REQUIREMENTS
The main requirements are the OpenLDAP client tools (ldapadd, ldapsearch, ldapdelete, ...). Other commands are called in the scripts but should come with your OS (sed, grep, cut, ...). CONFIGURATION
The main configuration of the ldapscripts is usually the file /etc/ldapscripts/ldapscripts.conf (or /usr/local/etc/ldapscripts/ldap- scripts.conf, depending on your system). Modify it to fit your needs before using the scripts. Each script also uses a "runtime" file, usu- ally /usr/lib/ldapscripts/runtime (or /usr/local/lib/ldapscripts/runtime). You don't need to modify this file. TEMPLATES
Each script that adds information to the directory uses a template. Templates are directly embedded at the end of the scripts but it is also possible to use external template files (see GTEMPLATE, UTEMPLATE and MTEMPLATE variables in the configuration file). Each template consists of a preformatted LDIF file using special keywords that will be replaced on-the-fly. Sample files are provided for your conve- nience : ldapaddgroup.template.sample, ldapadduser.template.sample and ldapaddmachine.template.sample. It is strongly advised to use those files instead of modifying the embedded (default) templates in the scripts. Sample templates include every keyword you can use. One special additional keyword is the <ask> keyword that will trigger user input to get the attribute value interactively. USING AS STANDALONE TOOLS
Each script can be used as a standard command-line tool. Check their man pages to get help. USING WITH SAMBA 3.x Each Samba 3.x smb.conf "xxx script" option has a matching script. Modify you smb.conf file this way to call them : # [...] add machine script = /usr/local/sbin/ldapaddmachine '%u' sambamachines add user script = /usr/local/sbin/ldapadduser '%u' sambausers add group script = /usr/local/sbin/ldapaddgroup '%g' add user to group script = /usr/local/sbin/ldapaddusertogroup '%u' '%g' delete user script = /usr/local/sbin/ldapdeleteuser '%u' delete group script = /usr/local/sbin/ldapdeletegroup '%g' delete user from group script = /usr/local/sbin/ldapdeleteuserfromgroup '%u' '%g' set primary group script = /usr/local/sbin/ldapsetprimarygroup '%u' '%g' rename user script = /usr/local/sbin/ldaprenameuser '%uold' '%unew' # [...] SEE ALSO

AVAILABILITY
The ldapscripts are provided under the GNU General Public License v2 (see COPYING for more details). The latest version of the ldapscripts is available on : http://contribs.martymac.org BUGS
Sometimes, that kind of message may appear in the log file : Additional information: value does not conform to assertion syntax . Setting slapd's debug level to 32 shows additional details : get_ava: illegal value for attributeType uidNumber . This is *not* a bug : the ldap- scripts tend to use the power of LDAP filters to easily find users (or groups) using either a uidNumber (numerical value) or a uid (string value). The following filter (used by ldapfinger(1)) will generate the above message if $_USER is a login : "(|(&(objectClass=posixAc- count)(|(uid=$_USER)(uidNumber=$_USER))) (&(objectClass=posixGroup)(|(cn=$_USER)(gidNumber=$_USER))))" because filter part "(uidNum- ber=$_USER)" requires an integer but gets a string. You can mostly ignore those warnings. January 1, 2006 ldapscripts(5)
