Count number of characters in different approaches

BASH

Step1: Using Linux wc command

# print the character counts of txt files (include the count of new line)
wc -m *.txt

# print the newline counts of txt files
wc -l *.txt

Step2: Check the Return symbol

  • e.g. \r\n costs 2 characters

Step3: number of characters = result of wc -m *.txt - result of wc -m *.txt * 2 - 1 (the last blank line costs 1 character)
