Shell script: count the copies of each line from a txt

Question

I would like to count the copies of each line in a txt file and I have tried so many things until know, but none worked well. In my case the text has just a word in each line.

This was my last try

echo -n 'enter file for edit: '
read file
for line in $file ; do
echo  'grep -w $line $file'
done; <$file

For example:

input file

a
a
a
c
c

Output file

a 3
c 2

Thanks in advance.

thnx!!! that worked but not copletely!! it misses the last line — m_papas, Nov 30 '12 at 17:19
