How to convert a CRLF into a \n string

Question

I am looking for a way to convert CRLF into a \n. Exemple :

What i have :

Line 1
Line 2

What i expect :

Line 1\nLine 2

I have a application that hates CRLF LF and end of line ?

Looking to do it in shell script or java application at worse.

Thank you

This could be solved with a second slash before the n to escape the first one.

Your code with a print statement would look something like this:

System.out.println("Line 1\\nLine 2");

Shell could be much faster really depending on how big the file is.

If you just want to change to say a "|"

cat file.txt | tr '\n' '|'

Output:

Line1|Line2|

if you must convert to a string (rather than one char)

cat file.txt | tr '\n' '|'  | sed s/\|/##/g

Output:

Line1##Line2##

Using GNU awk:

$ awk 'BEGIN{RS="\r?\n";ORS="\\n"}1' file

Output:

Line 1\nLine 2\n$

Works with mawk and Busybox awk, too.
