What keeps you from trying it (mayhap with the -x (--xtrace) option set)? Commands accepting multiple arguments don't even need the for loop nor the array. Try
.
Be aware that running a command blind folded with a resulting argument list that you don't know upfront is dangerous; applied to the wrong directories with the wrong options might render your system unuseable!
And, files with white space chars in their names might irritate / confuse the command.

tcl_wrongnumargs
Tcl_WrongNumArgs(3) Tcl Library Procedures Tcl_WrongNumArgs(3)__________________________________________________________________________________________________________________________________________________NAME
Tcl_WrongNumArgs - generate standard error message for wrong number of arguments
SYNOPSIS
#include <tcl.h>
Tcl_WrongNumArgs(interp, objc, objv, message)
ARGUMENTS
Tcl_Interp interp (in) Interpreter in which error will be reported: error message gets stored in its result object.
int objc (in) Number of leading arguments from objv to include in error message.
Tcl_Obj *const objv[] (in) Arguments to command that had the wrong number of arguments.
const char *message (in) Additional error information to print after leading arguments from objv. This typically gives the
acceptable syntax of the command. This argument may be NULL.
_________________________________________________________________DESCRIPTION
Tcl_WrongNumArgs is a utility procedure that is invoked by command procedures when they discover that they have received the wrong number
of arguments. Tcl_WrongNumArgs generates a standard error message and stores it in the result object of interp. The message includes the
objc initial elements of objv plus message. For example, if objv consists of the values foo and bar, objc is 1, and message is "fileName
count" then interp's result object will be set to the following string:
wrong # args: should be "foo fileName count"
If objc is 2, the result will be set to the following string:
wrong # args: should be "foo bar fileName count"
Objc is usually 1, but may be 2 or more for commands like string and the Tk widget commands, which use the first argument as a subcommand.
Some of the objects in the objv array may be abbreviations for a subcommand. The command Tcl_GetIndexFromObj will convert the abbreviated
string object into an indexObject. If an error occurs in the parsing of the subcommand we would like to use the full subcommand name
rather than the abbreviation. If the Tcl_WrongNumArgs command finds any indexObjects in the objv array it will use the full subcommand
name in the error message instead of the abbreviated name that was originally passed in. Using the above example, let us assume that bar
is actually an abbreviation for barfly and the object is now an indexObject because it was passed to Tcl_GetIndexFromObj. In this case the
error message would be:
wrong # args: should be "foo barfly fileName count"
