how to read how many times same result occurs?
Is there a way to read how many times each result occurs in a list,

say the list.txt has the results:
a
c
d
a
f
c
a
d
e

and I need to know how many times each of them occurs such as :
a=3
c=2
..etc.

Code:
awk '{a[$1]++}END{for (i in a) print i"="a[i]}' list.txt

Code:
#!/usr/bin/bash

for result in a b c d e f
do
    echo "${result}=$(grep -c $result list.txt)"
done

Result:

Code:
a=3
b=0
c=2
d=2
e=1
f=1
