Whilst trying to echo a line return (why use 8 lines when you can use one!!), I found the following…
- Irix 6.5.13
%echo '1\n22
1
22
- Gentoo linux (very recent one).
%echo '1\n22'
1\n22
%echo -e '1\n22'
1
22
So far so good!!!
- RHEL 3.0
echo -e '1\n22'
-e 1 n 22
-
Solaris 5.8
% echo -e '1\n22'
-e 1\n22
WTF?
