Description
When the var $CI is empty, the if condition is interpreted as missing an argument. It's a known but rare bug with a documented fix**. The error is:
./install.sh: line 271: [: ==: unary operator expected
I have already prepared a PR to fix this.
** The documented fix is in the footnote and reads:
As S.C. points out, in a compound test, even quoting the string variable might not suffice.
[ -n "$string" -o "$a" = "$b" ]may cause an error with some versions of Bash if $string is empty. The safe way is to append an extra character to possibly empty variables,[ "x$string" != x -o "x$a" = "x$b" ](the "x's" cancel out).
But, it's much more clear to just use [[ "new test" consistently since this script already used it in many places.
