Hi I have a file passwd_exmpl that contains:

tcpdump:x:72:72::/:/sbin/nologin
acctmgr:x:1000:1000:acctmgr:/home/acctmgr:/bin/bash

and I am tasked with getting the first and fifth field which I did here

cut -f 1,5 -d ':' --output-delimiter=' '  passwd_exmpl

which then outputs

root root
bin bin
daemon daemon
adm adm
lp lp
sync sync
shutdown shutdown
halt halt
mail mail
operator operator
games games
ftp FTP User
nobody Nobody
dbus System message bus
polkitd User for polkitd
unbound Unbound DNS resolver
colord User for colord
usbmuxd usbmuxd user
saslauth "Saslauthd user"
libstoragemgmt daemon account for libstoragemgmt
avahi Avahi mDNS/DNS-SD Stack
qemu qemu user
avahi-autoipd Avahi IPv4LL Stack
rpc Rpcbind Daemon
rpcuser RPC Service User
nfsnobody Anonymous NFS User
rtkit RealtimeKit
ntp 
chrony 
mysql MariaDB Server
radvd radvd user
abrt 
pulse PulseAudio System Daemon
gdm 
gnome-initial-setup 
postfix 
sshd Privilege-separated SSH
tcpdump 
acctmgr acctmgr

I need to just have the usernames and full names while excluding any of the roots and garbage I don't need and can't figure out how to go about this... Any help would be greatly appreciated, Thanks.

not sure what you mean by 'grabage', but here's something to start with:

awk -F: '!/(root|garbageGoesHere)/ && $5 {print $1,$5}' passwd_exmpl

Thanks for replying, but I need to only include names in the fifth field so I'm thinking if I could just grab the lines if the fifth field is in line with "capital first name" space "capital last name" then output only those lines so it wouldn't print something like "mail mail" or "games games" but instead lines like "wallack Phil Wallack" or "clocke1 Chris Locke" etc.

ok, how about:

awk -F: '$5~/^[A-Z].* [A-Z]/ {print $1,$5}' passwd_exmpl

Ok thanks your code worked I added a tail pipe to get exactly what I wanted:b:

awk -F: '$5~/^[A-Z].*[A-Z]/ {print $1,$5}' passwd_exmpl|tail -58

If "garbage" is root and other system accounts, and you are interested only in "normal" users, you might want to check for the uid ($3) to be >= 1000. The UID_MIN value if found in e.g. /etc/login.defs on linux system.
