I have 5 ip addresses and I have to make sure they are unique. They are
stored in variables ip1 ip2 ip3 ip4 and ip5

I want to run an operation that will return 5, i.e. they are unique.
Any other value will mean they are not unique.

If I put them in a string e.g.

"10.32.15.5 10.32.15.6 10.32.15.7 10.32.15.8 10.32.15.9"

And run uniq on them it doesnt work since uniq works on lines. How do I
get a similar operation to count unique occurences in a string?
Cheers

You can first turn them into lines and then uniq.
echo "10.32.15.5 10.32.15.6 10.32.15.7 10.32.15.8 10.32.15.9" | sed -n
's/ / \n/gp' | uniq

Cheers I will try that, I did try turning them into lines with sed,
with the \n but didnt put the /gp at the end of it. What does this do?

$ ip1=10.32.15.5
$ ip2=10.32.15.6
$ ip3=10.32.15.5

$ printf "%s\n" $ip{1..3}|sort -u
10.32.15.5
10.32.15.6

$ echo $ip{1..3} | gawk '!a[$0]++' RS="[ \n]"
10.32.15.5
10.32.15.6

Or:

$ printf "%s\n" 10.32.15.5 10.32.15.6 10.32.15.5|sort -u
10.32.15.5
10.32.15.6

$ printf "%s\n" 10.32.15.5 10.32.15.6 10.32.15.5|awk '!a[$0]++' RS="\n"
10.32.15.5
10.32.15.6

I apologise,
I overlooked this detail. You can try something like this:

$ a=(10.32.15.1 10.32.15.2 10.32.15.3 10.32.15.4 10.32.15.5)
$ nums=($(printf "%s\n" ${a[@]}|sort -u))
$ [ "${#a[@]}" -eq "${#nums[@]}" ] && echo "${#a[@]}" || echo "They are NOT
unique"
5

$ a=(10.32.15.1 10.32.15.1 10.32.15.3 10.32.15.4 10.32.15.5)
$ nums=($(printf "%s\n" ${a[@]}|sort -u))
$ [ "${#a[@]}" -eq "${#nums[@]}" ] && echo "${#a[@]}" || echo "They are NOT
unique"
They are NOT unique

Or:

awk '{for(i=1;i<=NF;i++) a[$i]=1}
END{for(x in a)++c;if(c==NF)print c;else print "Not unique"}'

ruby -e 'puts gets.split.uniq.size'

The 'g' says to replace all spaces, not just the first, and 'p' says to
print the result (if you omit the -n, you don't need p).
