I agree there, but I used the back-quotes as that's what the OP used while asking the question. You *can* nest commands using backquotes as well, but the number of escape chars would increase with every level.

__________________________________________________________________________________________________________________________________________________

NAME
concat - Join lists together SYNOPSIS
concat ?arg arg ...? _________________________________________________________________ DESCRIPTION
This command joins each of its arguments together with spaces after trimming leading and trailing white-space from each of them. If all the arguments are lists, this has the same effect as concatenating them into a single list. It permits any number of arguments; if no args are supplied, the result is an empty string. EXAMPLES
Although concat will concatenate lists (so the command: concat a b {c d e} {f {g h}} will return "a b c d e f {g h}" as its result), it will also concatenate things that are not lists, and hence the command: concat " a b {c " d " e} f" will return "a b {c d e} f" as its result. Note that the concatenation does not remove spaces from the middle of its arguments, so the command: concat "a b c" { d e f } will return "a b c d e f" (i.e. with three spaces between the a, the b and the c).

append(1T), eval(1T) KEYWORDS
