Since "[string range $a 0 end]" is by definition identical to $a,
you might as well write this as
exec tar zcf $tarFileName $fileList

Right.

TCL exec command will pass each argument separately (as if the values
are single-quoted after the variable expansion). To make it do what
you want, change it to:
eval exec tar zcf $tarFileName $fileList
Be careful not to have any spaces or TCL-special characters in
either $tarFileName or $fileList.
