How to count lines in a document?

Question

I have lines like these, and I want to know how many lines I actually have...

09:16:39 AM  all    2.00    0.00    4.00    0.00    0.00    0.00    0.00    0.0         


        

Answer 1

To count all lines use:

$ wc -l file

To filter and count only lines with pattern use:

$ grep -w "pattern" -c file  

Or use -v to invert match:

$ grep -w "pattern" -c -v file 

See the grep man page to take a look at the -e,-i and -x args...
