I have a log file sorted by IP addresses,
I want to find the number of occurrences of each unique IP address.
How can I do this with bash? Possibly listing the number of occurrences next to an ip, such as:



5.135.134.16 count: 5
13.57.220.172: count 30
18.206.226 count:2


and so on.



Here’s a sample of the log:

You can use grep and uniq for the list of addresses, loop over them and grep again for the count:



for i in $(<log grep -o '^[^ ]*' | uniq); do
printf '%s count %dn' "$i" $(<log grep -c "$i")
done


grep -o '^[^ ]*' outputs every character from the beginning (^) until the first space of each line, uniq removes repeated lines, thus leaving you with a list of IP addresses. Thanks to command substitution, the for loop loops over this list printing the currently processed IP followed by “ count ” and the count. The latter is computed by grep -c, which counts the number of lines with at least one match.



Example run



$ for i in $(<log grep -o '^[^ ]*'|uniq);do printf '%s count %dn' "$i" $(<log grep -c "$i");done
5.135.134.16 count 5
13.57.220.172 count 9
13.57.233.99 count 1
18.206.226.75 count 2
18.213.10.181 count 3

    This solution iterates over the input file repeatedly, once for each IP address, which will be very slow if the file is large. The other solutions using uniq -c or awk only need to read the file once,

You can use cut and uniq tools:



cut -d ' ' -f1 test.txt | uniq -c
5 5.135.134.16
9 13.57.220.172
1 13.57.233.99
2 18.206.226.75
3 18.213.10.181


Explanation :




  • cut -d ' ' -f1 : extract first field (ip address)


  • uniq -c : report repeated lines and display the number of occurences

If you don't specifically require the given output format, then I would recommend the already posted cut + uniq based answer



If you really need the given output format, a single-pass way to do it in Awk would be



awk 'c[$1]++ ENDfor(i in c) print i, "count: " c[i]' log


This is somewhat non-ideal when the input is already sorted since it unnecessarily stores all the IPs into memory - a better, though more complicated, way to do it in the pre-sorted case (more directly equivalent to uniq -c) would be:



awk '
NR==1 last=$1
$1 != last print last, "count: " c[last]; last = $1
c[$1]++
END print last, "count: " c[last]
'


Ex.



$ awk 'NR==1 last=$1 $1 != last print last, "count: " c[last]; last = $1 c[$1]++ ENDprint last, "count: " c[last]' log
5.135.134.16 count: 5
13.57.220.172 count: 9
13.57.233.99 count: 1
18.206.226.75 count: 2
18.213.10.181 count: 3

    Here is one possible solution:





    IN_FILE="file.log"
    for IP in $(awk 'print $1' "$IN_FILE" | sort -u)
    do
    echo -en "$IPtcount: "
    grep -c "$IP" "$IN_FILE"
    done


    • replace file.log with the actual file name.

    • the command substitution expression $(awk 'print $1' "$IN_FILE" | sort -u) will provide a list of the unique values of the first column.

    • then grep -c will count each of these values within the file.


    $ IN_FILE="file.log"; for IP in $(awk 'print $1' "$IN_FILE" | sort -u); do echo -en "$IPtcount: "; grep -c "$IP" "$IN_FILE"; done
    13.57.220.172 count: 9
    13.57.233.99 count: 1
    18.206.226.75 count: 2
    18.213.10.181 count: 3
    5.135.134.16 count: 5

      One could use sed, e.g. sed -E 's/ *(S*) *(S*)/2 count: 1/' to get the output exactly like OP wanted.

    If you don't specifically require the given output format, then I would recommend the already posted cut + uniq based answer



    If you really need the given output format, a single-pass way to do it in Awk would be



    awk 'c[$1]++ ENDfor(i in c) print i, "count: " c[i]' log


    This is somewhat non-ideal when the input is already sorted since it unnecessarily stores all the IPs into memory - a better, though more complicated, way to do it in the pre-sorted case (more directly equivalent to uniq -c) would be:



    awk '
    NR==1 last=$1
    $1 != last print last, "count: " c[last]; last = $1
    c[$1]++
    END print last, "count: " c[last]
    '


    Ex.



    $ awk 'NR==1 last=$1 $1 != last print last, "count: " c[last]; last = $1 c[$1]++ ENDprint last, "count: " c[last]' log
    5.135.134.16 count: 5
    13.57.220.172 count: 9
    13.57.233.99 count: 1

            Here is one possible solution:





            IN_FILE="file.log"
            for IP in $(awk 'print $1' "$IN_FILE" | sort -u)
            do
            echo -en "$IPtcount: "
            grep -c "$IP" "$IN_FILE"
            done


            • replace file.log with the actual file name.

            • the command substitution expression $(awk 'print $1' "$IN_FILE" | sort -u) will provide a list of the unique values of the first column.

            • then grep -c will count each of these values within the file.


            $ IN_FILE="file.log"; for IP in $(awk 'print $1' "$IN_FILE" | sort -u); do echo -en "$IPtcount: "; grep -c "$IP" "$IN_FILE"; done
