How do you append to an already existing string?

Question

I want append to a string so that every time I loop over it will add say \"test\" to the string.

Like in PHP you would do:

$teststr = \"test1\\n\"
$t         


        

Answer 1

#!/bin/bash

msg1=${1} #First Parameter
msg2=${2} #Second Parameter

concatString=$msg1"$msg2" #Concatenated String
concatString2="$msg1$msg2"

echo $concatString 
echo $concatString2
