==
. For assignment, use =
. For comparison, use
[
/[[
.var==value
Assignment:
var=value
Comparison:
[ "$var" = value ]
ShellCheck has noticed that you're using ==
in an
unexpected way. The two most common reasons for this is:
You wanted to assign a value but accidentally used
==
instead of =
.
You wanted to compare two values, but neglected to use
[ .. ]
or [[ .. ]]
.
If you wanted to assign a literal equals sign, use quotes to make this clear:
var="=sum(A1:A10)"
