title: /usr/bin/wish：don't have that file or directory
body: <p>I have a browse.tcl script, when I exec it, the Ubuntu shows :
  &quot;bash: ./browse.tcl：/usr/bin/wish：don't have that file or directory&quot;
  I tried to find the &quot;wish&quot;
  usr/bin$ find wish
  find: ‘wish’: don't have that file or directory</p>
  <p>How can I get it?</p>
