How to properly nest Bash backticks

Question

Either I missed some backlash or backlashing does not seem to work with too much programmer-quote-looping.

$ echo \"hello1-`echo hello2-\\`echo hello3-\\`ech         


        

Answer 1

It's a lot easier if you use bash's $(cmd) command substitution syntax, which is much more friendly to being nested:

$ echo "hello1-$(echo hello2-$(echo hello3-$(echo hello4)))"
hello1-hello2-hello3-hello4
