Substituting in a string

[Balu]

Hi,
what do i have to do to let te following command subtitute de %n in a string with the variable $nick and so on?

[string map -nocase {%n "$nick" %1 "[lindex $args 0]" %2 "[lindex
$args 1]" %3 "[lindex $args 0]"} [join $command_output " "]]

{} defeats variable/command substitution. Use 'list' to make the map.

thx, that helped me out, the script is running fine now, it even escaped the chars ; and $ out. Don't need to work around that anymore
