tcl vs system copy

[Yves de Champlain]

Hi

How come

     copy -f [glob -directory ${filespath} common_*.tiff] \
         ${destroot}${prefix}/$gslibrary/Images

and

     file copy -force [glob -directory ${filespath} common_*.tiff] \
         ${destroot}${prefix}/$gslibrary/Images

do not work while

     system "cp -f ${filespath}/common_*.tiff \
         ${destroot}${prefix}/$gslibrary/Images"

does ?
