Parser error

This page is about how ShellCheck reports parser errors, to aid you in finding problems. If you're getting a parser error for code you know or think is correct, you should submit a bug with an example!
When ShellCheck is unable to parse a file, it'll output several errors to help pinpoint the problem:
Consider this script, with a missing double quote on line 1:
ssh host "$cmd
echo "Finished"
Bash says:
file: line 2: unexpected EOF while looking for matching `"'
file: line 3: syntax error: unexpected end of file
Shellcheck says:
In file line 1:
ssh host "$cmd
^-- SC1009: The mentioned parser error was in this simple command.
In file line 2:
echo "Finished"
^-- SC1073: Couldn't parse this double quoted string.
^-- SC1072: Unexpected eof. Fix any mentioned problems and try again.
- One error showing the direct problem (SC1072, unexpected eof) (Note: see #1036)
- One error showing the construct being parsed (SC1073)
- One info showing the outer construct being parsed (SC1009)
- Potentially some specific suggestions, such as when missing a
fi
.
Here, shellcheck says that the command on line 1 is faulty, which makes it easier to find and fix the actual problem.
