Use the program wc.
To count the number of lines:
-lwc -l myfile.shTo count the number of words:
-wwc -w myfile.sh
See man wc for more options.

3Be aware that the documentation says: "print the newline counts" when using the
-loption, so if your file have three lines (two \n), thus,wc -l myfile.shwill return 2. Feb 17, 2022 at 14:36
As mentioned by souravc, you can use wc for this:
$ wc -w statusToFiles.sh
10 statusToFiles.sh
$ wc -l statusToFiles.sh
6 statusToFiles.sh
To only display the count itself, you can pipe that output to awk, like this:
$ wc -l statusToFiles.sh | awk '{ print $1 }'
6
...or as kos mentioned below:
$ < statusToFiles.sh wc -l
6
You can use grep command with blank matching string
grep "" -c file_path

1or with non-blank matching string if you want to count non-empty lines
grep -c . file(The period . matches any single character.)– jakunMay 29, 2020 at 16:01 -

You can also output the entire file with line numbers in front of every line using the command below:
cat -n myfile

This is useless for big files (e.g. 250MB), instead it may causing freeze Jun 29, 2020 at 12:39
