In Bash, you can concatenate (join) two or more strings together using the + operator. For example, if you have two strings $str1 and $str2, you can concatenate them like this:
str1="Hello" str2="World" concatenated_string="$str1 $str2"
This will set the concatenated_string variable to "Hello World", which is the concatenation of $str1 and $str2 with a space in between.
Alternatively, you can use the += operator to concatenate strings in Bash. This operator appends the right-hand side string to the end of the left-hand side string. For example:
str1="Hello" str2="World" str1+=" $str2"
This will set the str1 variable to "Hello World", which is the concatenation of $str1 and $str2 with a space in between.
Both of these methods can be used to concatenate strings in Bash. The choice of which method to use depends on your specific situation and preference.
