Hi,

I want to get a Line count of a file and append that at the end of the file. The Line count should not include the Headers :

------------------
COL1,COL2,COL3
123,abc,011
111,abd,0212
Record Count: 2
-------------------

Thanks.

How can you tell what is are the Headers?

Header is always the 1st row.

here is your solution

wc -l file_name.txt | nawk '{print "\tRecord count :" expr $1-1}' >> file_name.txt

Thanks
