Append line count to each line

Shell Programming and Scripting
1

Hello forum,

I need to append the total line count to the end of each line in a file.

The file where this line count needs to be appended is generated by this script:

The script does a word frequency count by the first column of a file.

if I add wc -l at the end then the line count appears only in the last line. But I want the line count to appear at the end of each line.

Thanks!

Hi
Provide a sample input file and an expected output file.

Sample input:

aaa bbb ccc
aaa bbb ccc
ddd eee fff
ddd eee fff

The output from my script will be:
2 aaa
2 ddd

I want the sum of occurrence of aaa and bbb =2+2 i.e. the line count to show up at the end of each line

i.e. output will be:

2 aaa 4
2 ddd 4

Thanks that works fine except that the sorting by the number of occurrences of the words is not there. I appreciate your help.
