====== BASH - Strings - Concatenating Strings ======

To concatenate two variables you can just write them one after another:

<code bash>
#!/bin/bash

string1="Hello"
string2="World"
string=$string1$string2

echo "$string is the concatenation of $string1 and $string2."
</code>

<WRAP info>
**NOTE:**  The following program outputs the string “HelloWorld is the concatenation of Hello and World.”.
</WRAP>

----

<code bash>
a='Hello'
b='World'
c="${a} ${b}"
echo "${c}"
> Hello World
</code>

or

<code bash>
foo="Hello"
foo="${foo} World"
echo "${foo}"
> Hello World
</code>

----

<code bash>
var="abcdefgh"
echo ${var:0:(-1 -4)}XYZ
</code>

returns:

<code bash>
abcXYZ
</code>
