Escaping single quotes inside single quotes in bash

In bash, you can use the backslash character ("\") to escape any character. However, if a single quote is inside single quotes, it cannot be escaped with a backslash character. For example:

alias ycd='some_command'

works fine but

alias ycd='command -option 'something''
alias ycd='command -option \'something\''

both of the above return errors.

A trick around this problem is to use both quotes i.e. use double quotes to surround the single quote and single quotes again to surround the single quote.

using ' is that same as '"'"'

To rewrite the example above"

alias ycd='command -option '"'"'something'"'"''

Note that the first and last single quotes are not converted.
