Shell Newline

Solved

Hello,
I have a problem that I've been trying to solve since Friday without success. In fact, I'm writing a shell script, where I need to insert a line using sed, followed by a newline and then another line:
sed s/line_to_replace/line1\nline2/g file > file;
The problem is that the newline is not recognized, and I just get line1nline2.
I doubled the double slash, and I get the same thing; when I triple it, I get line1\nline2.
I should mention that I'm using Putty to connect to the server; unfortunately, I have no choice of tool.
Thank you for your help.

    Hello,

    What operating system are you using on your server?
    What version of "sed"?

    Try with the ASCII code: 

    sed 's/lign_remplacer/ligne1\x0Aligne2/g' fichier > fichier

    It's a ZERO and not a capital O...

    Always the same problem: it shows me ...line1x0Aline2...
    How can I know the version of the server and the sed command please?
    Thank you

      Do you at least know if the server is running GNU/Linux or UNIX?

      Try: 

      lsb_release -a or cat /etc/{release,version,issue}


      For "sed": 

      sed --version

    The command you gave me didn't work, I tried the oslevel command, it returned: 5.2.0.0.
    uname -a returned: AIX xxxxx 2 5 .....
    For sed, the command didn't work.

      Indeed, on AIX, "sed" can be rather temperamental ;-((

      Try it like this: 

      sed 's/lign_remplacer/ligne1\<ENTREE> ligne2/g' file > file


      <ENTREE> should be executed, not taken literally, right? ;-))

      After the backslash, you press Enter and continue the rest of the syntax on the next line.

      You press <Enter> without the backslash before it ;-)

      Finally no, I may have said something stupid, you do the same with the anti-slash and the <Enter> ;-)

    It worked, but by adding another backslash: \\
    Thank you very much for this help, you saved my day! :-)
