regular expression (regex) of end of the string

I want to add the symbols related to the end of the string in my regexp

echo aaa.bbb.ccc=3 | grep  "aaa\.[^.]\+\.ccc=3"

I tried the following symbols but it does not works

echo aaa.bbb.ccc=3 | grep  "aaa\.[^.]\+\.ccc=3\Z"
echo aaa.bbb.ccc=3 | grep  "aaa\.[^.]\+\.ccc=3$/"

How I can add end of string symbol to my regexp?

Update

question 2)

echo aaa.bbb.ccc=3 | grep  "aaa\.[^.]\+\.ccc=3"
#                                             ^
#                                             |
#           What symbols I have to add here in order to say I m expecting end of string or any thing except the digits [^0-9]?

You can use

\($\|[^0-9]\)

to match either the end of input or a non-digit character.

Use echo aaa.bbb.ccc=3 | grep "aaa\.[^.]\+\.ccc=3$"

Answer 2:

Use echo aaa.bbb.ccc=3 | grep "aaa\.[^.]\+\.ccc=3[^0-9]*"

[^0-9]* will include $ also.
