bash - Use of apostrophe (single-quote) in a Git commit message via command line

I am trying to take this one step further. How could this work in a standard Bash shell?

git commit -m 'cracked enigma's code'

Could this simply be done with backslash-escaping like the following?

git commit -m 'cracked enigma\'s code'

Further, how could double-quotes be used? Also by backslash-escaping? Would that be the best way? Are there any good alternative ways?

git commit -m 'cracked the "real" enigma's code'

Answer

Use double quotes:

git commit -m "cracked enigma's code"

Or, if your message contains other special characters, use double quotes or backslash only for the single quote:

git commit -m 'cracked $enigma'"'"'s code'
git commit -m 'cracked $enigma'\''s code'
