Quotes in Bash
When we want variables to store more complex values, we need to make use of quotes. Quotes are used to handle texts and filenames with a space character. It is because Bash uses a space to determine separate items.
When we enclose our contents in quotes, we are indicating to Bash that the content within the quotes should be considered as a single item.
Quote with String
While working with simple texts and string, there will be no difference either we use a single quote or double quote.
Quote with Variable
It should be noted that the shell variable expansion will only work with double-quotes. If you define any variable in single quotes, then it will not be considered as a variable.
Bash (Bourne Again Shell) is a command line interpreter that typically runs in a text window where user can interpret commands to carry out various actions. The combination of these commands as a series within a file is known as a Shell Script. Bash can read and execute the commands from a Shell Script.
