No, because neither of those are the inputs. The input was the systemd file in the image. The whole command was not printed in the error, only surrounding context. The single-quote was indicating the ending of that context(because it was the end of the line) printed by the error.
The same thing was done with
`)'
on the first line of errorHere's what I'm reading:
startup-script
line 27 threw the error.I'm reading this and interpreting that line 27 of that script is
sudo echo "# FYI quotes(") must be escaped with \ like \"
I am confused why there is no trailing double quote, the last 3 chars should be
\""
so perhaps this is a bad assumption but the best I can do with the available information.So the fix here is to change
startup-script
line 27 so that you're notecho
ing things that might contain characters that might be interpreted by echo or your shell.Now if
startup-script
is provided by your distro, there may be a reason that it's using echo, but I will tell you now whatever dipshit reason they provide they're fucking wrong because EXHIBIT A:# "
fucks the script and rule 0 of linux is "don't break userspace".Everything else allows any printable char after the
#
in a comment, that script is not special, comments are not to be interpreted by the program. That is a show-stopping bug instartup-script
and must be fixed.EOF
And your interpretation is wrong. Line 27 is actuallly
sudo echo "${server_service}" > /lib/systemd/system/server.service
${server_service}
is read from the file I posted in the 2nd image. Since it was a test script I hadn't bothered implementing any escaping tools, I wanted to make sure terraform allowed this first.And there's your problem. You're
echo
ing using double quotes which will interpret characters. Don't do that. That's a bug.cat
orcp
the file to the destination;printf
if the contents are all in that variable.No, you're still misunderstanding what's being done.
${server_service}
is an injected string, the string is the whole contents of the file. That file is not stored locally on the server, except through being injected here(by a terraform file template). And no,printf
won't be any better thanecho
because its not format string, and I don't want any formatting from printf applied to it.
