In Linux, single quotes and double quotes are not the same and have different meanings.
Single quotes ('
) preserve the literal value of all characters within the quotes. This means that any variables or special characters within the single quotes will be treated as plain text and not interpreted as part of a command or script.
For example, if you run the command echo '$HOME'
in a Linux terminal, it will output $HOME
literally, without trying to interpret it as the value of the HOME
environment variable.
On the other hand, double quotes ("
) allow for variable expansion and some special characters to be interpreted. Variables within the double quotes will be expanded to their values, and certain special characters like $
and \
will be interpreted.
For example, if you run the command echo "$HOME"
, it will output the value of the HOME
environment variable, which is usually the path to the current user’s home directory.
So, single quotes and double quotes have different meanings in Linux and are not interchangeable.
