They are confusing: echo $( echo $( echo $( echo str ) ) ) echo ` echo \` echo \\\` echo str \\\` \` ` echo $( echo \\ ) echo ` echo \\\ ` Backticks are also easily mistaken for single quotes and not readily avaiable on intl. keyboards.

I'm not sure if this behaviour is affected by IFS Not sure what you mean by this, or maybe it's shell dependant. Both print the same: dash -c 'echo "$(printf %s\\n str str2)"' dash -c 'echo "`printf %s\\\n str str2`"' And testing with literal newlines also works: dash -c 'echo "$(printf %s\\n "new line")"' dash -c 'echo "`printf %s\\\n \"new line\"`"'
