How to escape single quotes within single quoted strings

Question

Let\'s say, you have a Bash alias like:

alias rxvt=\'urxvt\'

which works fine.

However:

Answer 1

Another way to fix the problem of too many layers of nested quotation:

You are trying to cram too much into too tiny a space, so use a bash function.

The problem is you are trying to have too many levels of nesting, and the basic alias technology is not powerful enough to accommodate. Use a bash function like this to make it so the single, double quotes back ticks and passed in parameters are all handled normally as we would expect:

lets_do_some_stuff() {
    tmp=$1                       #keep a passed in parameter.
    run_your_program $@          #use all your passed parameters.
    echo -e '\n-------------'    #use your single quotes.
    echo `date`                  #use your back ticks.
    echo -e "\n-------------"    #use your double quotes.
}
alias foobarbaz=lets_do_some_stuff

Then you can use your $1 and $2 variables and single, double quotes and back ticks without worrying about the alias function wrecking their integrity.

This program prints:

el@defiant ~/code $ foobarbaz alien Dyson ring detected @grid 10385
alien Dyson ring detected @grid 10385
