This nesting style can lead to confusion, since it must be doubled (as in Bourne Shells). It'd be nice to have a $() wrapper for it.

Apparently, this nesting style is very different. I can't seem to find a way to nest three or more commands, but this works: echo "`echo "\`"pwd"\`"`"

Either there's no way to do so or I'm failing to understand.

echo "`{echo,"'`pwd`'"}`"
This works too, but still no luck for multiple nesting.

[Krush206]

echo "`echo "\"'`echo "\`"pwd"\`"`'\""`"
For three nests, this works. This is very complicated.

I'm still investigating further.

echo "`echo "\"'`echo "\"'\''`echo "\`"pwd"\`"`'\''\""`'\""`"
Finally made four nests. This nesting style is ridiculous, but does work.

This works too.
