Line endings

Updated: 08 February 2024

Write lines of text to file, with alternating line-ending type: CRLF, LF then finally LF. Use hexdump to verify the result

echo -n -e \\x61\\x0d\\x0a\\x62\\x0a\\x63\\x0a > file
cat file
hexdump --canonical file

Output

a                                                                    
b                                                                    
c                                                                    
00000000  61 0d 0a 62 0a 63 0a                              |a..b.c.|
