awk 2 files

Hello
I have 2 files

file1
Code:
/tmp/xxx
/tmp/yyy
/tmp/ccc

file2
Code:
/tmp/aaa
/tmp/ccc
/tmp/yyy

I would like have output
Code:
/tmp/aaa - NO

So check all entries from file1 in file2 and if entry from file2 not exist in file1 display it.

Can someone help write code in AWK?

Are the input files sorted?

Old 02-18-2015
Code:
sort file1 >file1.tmp
sort file2 >file2.tmp
diff file1.tmp file2.tmp

Code:
awk 'FNR==NR {f1[$1];next} !($1 in f1)' file1 file2

With a recent bash that provides "process substitution", try
Code:
comm -13 <(sort file1) <(sort file2)
/tmp/aaa

Code:
#/bin/bash
for i in `cat file2`
do
     grep -w $i file1 > /Dev/null 2>&1 || echo $i
done
