For example, with some work to log itself, you could use here documents, which would mean log <<EOF<Enter>here's my entry<Enter>EOF<Enter> It's more typing than simply escaping, though. Similarly, you could use stdin like log<Enter>here's my entry<Enter><Ctrl-D> Again, more typing. You could make log interactive, so you type a line and hit <Enter>, but it stays running so you can just leave it go in a separate terminal. You could find or write your own custom shell that has simpler escaping. Many options.

OK, fair enough. Assuming you're logging one message at a time (with other commands in between your log entries), there isn't a whole lot more you can do. For casual things like this, I've personally just gotten used to using quotes and escaping, depending on the specific text in each message. E.g., I'd use log Plain old string vs. log "Don't look" vs. log 'This "job" is too much fun' vs log I could sure use \$20. Unfortunately, if that bit of extra typing is unacceptable for you, then you would need to modify your requirement of being able to type the messages at a bash shell prompt.

Basically, from the terminal, log the stuff isn't working. Then it will input the text after log into a text file with date and timestamp.

You can use double quotes, as in log "it's my life", but that runs into similar problems if you'll ever have double quotes in your string (or any other characters that need to be escaped (see the question I linked in my answer). This is a problem with shell commands in general. You can use input redirection or here documents, but then you no longer have a one-line command. Can you tell me more about how your log command will be used?

Is there a way to achieve the functionality of my log script without having to escape any characters?

Explained why unmatched single apostrophes result in the extra prompt lines the OP sees
