====== Scripting - EOL ======

Some hints about the EOL characters on Windows and Linux.

===== Overview =====

^             ^ Linux     ^ Windows                       ^
| Written-out | line feed | carriage return and line feed |
| Short cut   | LF        | CRLF                          |
| Meta chars  | \n        | \r\n                          |
| ASCII-Code  | 0a        | 0d0a                          |

===== Real life =====

Create files which contain only the EOL characters.
<code>
# printf "\n" > linux
# printf "\r\n" > win
</code>

Show hexdump of the files.
<code>
# xxd linux 
00000000: 0a                                       .
# xxd win 
00000000: 0d0a                                     ..
</code>

Let file classify the files.
<code>
# file linux 
linux: very short file (no magic)
# file win 
win: ASCII text, with CRLF line terminators
</code>

Look how GNU cat prints the EOL characters.
<code>
# cat -A linux 
$
# cat -A win 
^M$
</code>
