This is a Unicode quote. Delete and retype it (or ignore/doublequote for literal).

Problematic code:

echo 'hello world’

Correct code:

echo 'hello world'

Rationale:

Some software, like OS X, Word and WordPress, may automatically replace your regular quotes with slanted Unicode quotes. The shell does not recognize these quotes and will not respect them.

In this case, you have slanted single quotes in a single quoted string. Try deleting and retyping them, and/or disable “smart quotes” in your editor or OS.

Exceptions

If you want to use literal slanted single quotes for typographic reasons, you can put them in double quotes to make ShellCheck ignore them:

printf "Warning: ‘wakeonlan’ is not installed.\\n"

You can also just ignore this warning.

ShellCheck

Each individual ShellCheck warning has its own wiki page like SC1000. Use GitHub Wiki's "Pages" feature above to find a specific one, or see Checks.
