Don't put spaces around the = in assignments.

Note: Removed in v0.7.2 - 2021-04-20

Problematic code:

foo = 42

Correct code:

foo=42

Rationale:

Shells are space sensitive. foo=42 means to assign 42 to the variable foo. foo = 42 means to run a command named foo, and pass = as $1 and 42 as $2.

Exceptions

If you actually wanted to run a command named foo and provide = as the first argument, simply quote it to make ShellCheck be quiet: foo "=" 42.
