$ wget -q -O - 'http://www.nalanta.com/2008/08/12/egrep-multiple-
pattern-search/' | sed -ne '/Requirement :/,${s/<[^>]*>//g;s/
\‘/'\''/g;s/e '\''/e'\''/;p;/#$/q;}'
Requirement : Find the root and oracle users informations from /etc/
passwd
[root@tritya root]# egrep 'root|oracle' /etc/passwd
root:x:0:0:root:/root:/bin/bash
oracle:x:300:200:oracle:/home/oracle:/bin/bash
[root@tritya root]#
$

No, that's not a very good answer.
That would also match lines such as:
devil:x:100:100:root of all evil:/home/devil:

Better answers:
# egrep '^root:|^oracle:' /etc/passwd
# grep -e '^root:' -e '^oracle:' /etc/passwd
# sed -ne '/^root:/p;/^oracle:/p' /etc/passwd
# awk -F: '{if($1=="root"||$1=="oracle")print;}' /etc/pass
