String concatenation and if-fi constructs in bash fail

- Subject: String concatenation and if-fi constructs in bash fail
I am observing that string concatenation in bash 3.2.3(5), as well as in
3.1.17 (not exactly sure, the one that comes with the distribution),
overwrites the first string variable during concatenation:
Example code:
string1="one"
string2="two"
echo $string1
echo "$string1+"
echo "$string1+$string2"
echo "The number 2: $string2"
echo "This is $string1 + $string2"
Example results:
one
+ne
+two
The number 2: two
+ twos one
-------------------------------------------------------------------------------------
Adding an if-fi construction in the bash script leads to an error:
Example:
if $x==5; then
echo "Blah1"
else
echo "Blah2"
fi
Example result:
for line XX which is the last +1 line of the script, the
following message is displayed
script_path: line XX: syntax error: unexpected end of file
Cheers,
Borislav
