One liner for counting unique IP addresses from nginx logs

# One liner for counting unique IP addresses from nginx logs
# Feel free to comment with better ideas - I'm sure it's not the best way of doing this (I'm no awk ninja!)
#
# Sample output:
# 
# $ cat example.com.access.log | awk -F " " '{a[$1]++ } END { for (b in a) { print b, "\t", a[b] } }'
# 66.65.145.220 49
# 92.63.28.68 126

cat example.com.access.log | awk -F " " '{a[$1]++ } END  { for (b in a) { print b, "\t", a[b] } }'

Ogali ftw

Even better:

cat example.com.access.log | cut -f1 -d ' ' | uniq -c | sort -g -r

On second thought, that's not right...

Here it is!

$ cat example.com.access.log | cut -f1 -d ' ' | sort | uniq -c | sort -g -r

Can be rewritten with the UUoC ommitted :
<example.com.access.log cut -f1 -d ' ' | sort | uniq -c | sort -g -r

Or:
cut -f1 -d ' ' example.com.access.log | sort | uniq -c | sort -g -r

I have log file, sized 1.7 GB,
does these solutions work for that???

@Fazel94 hell yes

awk '{print $1 " " $3 " " $4}' access.log| sort | uniq -c | sort -nr
will give you the time frame
