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

wc -l <file.txt>

Or

command | wc -l

Answer 2

Use nl like this:

nl filename

From man nl:

Write each FILE to standard output, with line numbers added. With no FILE, or when FILE is -, read standard input.

Answer 3

I just made a program to do this ( with node )

npm install gimme-lines
gimme-lines verbose --exclude=node_modules,public,vendor --exclude_extensions=html

Answer 4

Or count all lines in subdirectories with a file name pattern (e.g. logfiles with timestamps in the file name):

wc -l ./**/*_SuccessLog.csv

Answer 5

This drop-in portable shell function [ℹ]  works like a charm. Just add the following snippet to your .bashrc file (or the equivalent for your shell environment).

# ---------------------------------------------
#  Count lines in a file
#
#  @1 = path to file
#
#  EXAMPLE USAGE: `count_file_lines $HISTFILE`
# ---------------------------------------------
count_file_lines() {
    local subj=$(wc -l $1)
    subj="${subj//$1/}"
    echo ${subj//[[:space:]]}
}

This should be fully compatible with all POSIX-compliant shells in addition to bash and zsh.

Answer 6

wc -l file_name

for eg: wc -l file.txt

it will give you the total number of lines in that file

for getting last line use tail -1 file_name
