You did not say exactly what "does not work" means, but I suppose the
problem is that you get literal "\n" in the file instead of newlines. The
shell will not convert those when you execute the specific command you
presented, and I guess Puppet expects to receive a literal value. In that
case, this is more a shell problem than a Puppet problem, and probably it
can be solved via the shell. Details vary depending on which shell you are
using, but there are multiple possibilities, among them:
1. Include literal newlines in your parameter instead of "\n". In bash, at
least, this works as long as the newlines are quoted. For example:
$ puppet resource file hello_world \
path=/tmp/hw.txt \
ensure=file \
content="hello
world
"
2. Use the shell's form for C-style escapes. In bash, that would be:
$ puppet resource file hello_world \
path=/tmp/hw.txt \
ensure=file \
content=$'hello\nworld\n'
3. Obtain the wanted value as the output of a command. In bash, that would
be:
$ puppet resource file hello_world \
path=/tmp/hw.txt \
ensure=file \
content="`echo -e 'hello\nworld'`"
(By itself, however, this last alternative cannot produce a trailing
newline in the content, as shell command substitution eats those.)
