Count number of characters in different approaches
BASH
Step1: Using Linux wc command
# print the character counts of txt files (contains the count of return symbol) 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 (not contains the return symbol) = result of wc -m *.txt - result of wc -m *.txt * 2 - 1 (the last blank line costs 1 character)
