It seems that variable expansion adds a space before and after the variable's
value.
Since the test must be "A=B", without space, results seems to be wrong
(unless i'm doing something wrong).
if [ A=A ]; then echo "foo" ; fi
foo
if [ A=B ]; then echo "foo" ; else echo "bar"; fi
bar
error: false
## WRONG
if [ A = A ]; then echo "foo" ; fi
foo
if [ A = B ]; then echo "foo" ; fi
foo
## WRONG
if [ "A" = "A" ]; then echo "foo" ; fi
foo
if [ "A" = "B" ]; then echo "foo" ; fi
foo
## WRONG
if [ "A" == "A" ]; then echo "foo" ; fi
foo
if [ "A" == "B" ]; then echo "foo" ; fi
foo
## WRONG
if [ A = A ]; then echo "foo" ; fi
foo
if [ A = B ]; then echo "foo" ; fi
foo
## WRONG
if [ A==A ]; then echo "foo" ; fi
error: false
if [ A==B ]; then echo "foo" ; fi
error: false
#### WITH VARIABLES ######
set X=A
echo $X
A
echo $(X)
echo ${X}
A
## WRONG
if [ $X=A ]; then echo "foo" ; fi
foo
if [ $X=B ]; then echo "foo" ; fi
foo
if [ ${X}=A ]; then echo "foo" ; fi
foo
if [ ${X}=B ]; then echo "foo" ; fi
foo
## Variables
echo ${X}=A
A =A
echo A=${X}
A= A
echo A=$X
A= A
echo "A=$X"
A= A

I'll try to simulate that.

Doc updated, thanks.
