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:

18.206.226 count:2
and so on.

If you really need the given output format, then since your input is already sorted, a single-pass way to do it in Awk would be
awk '
NR==1 last=$1
$1 != last print last, "count: " c[last]; last = $1
c[$1]++
END print last, "count: " c[last]

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

If not already sorted, then
awk 'c[$1]++ ENDfor(i in c) print i, "count: " c[i]' log
(This works on sorted input as well, however unnecessarily reads all the IPs into memory.)

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

If you really need the given output format, then since your input is already sorted, a single-pass way to do it in Awk 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

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

With “bash”, do you mean the plain shell or the command line in general?
