Finding new line character or special characters in txt file ?

[kri shan]

How to check(using script/command line) any new line character or special characters in the text file(.txt) in Unix/Linux.

What are you trying to achieve?

If all you want to do is count how many lines are in a file, you might want to look at the wc program.

If you want to be able to count specific characters, you might want to look at the grep command (take a look at the '--count' option).

But grep counts matching rows, not characters.
