In PHP, strings are concatenated together as follows: $foo = "Hello"; $foo .= " World"; Here, $foo becomes "Hello World". How is this accomplished in Bash?

In Bash, you can concatenate strings using various methods. One common way is to use the concatenation operator +=. Here's how you can do it with an example:

bash
# Define two strings
foo="Hello"
bar=" World"

# Concatenate the strings
foo+="$bar"

# Print the concatenated string
echo "$foo"

In this example:

  • We have two strings, foo and bar, with the values "Hello" and " World," respectively.

  • We use the += operator to concatenate bar onto the end of foo, effectively joining them together.

  • Finally, we use echo to print the concatenated string, which will display "Hello World."

This method allows you to concatenate strings in Bash, similar to how you would do it in PHP with the . operator. You can use this technique to build and manipulate strings in your Bash scripts.
