Oh, BTW I read last week that ubuntu still uses bash for user shells, but uses dash as a lighter, faster shell for &quot;system stuff&quot;.  I am not sure what that means other than /bin/sh links to /bin/dash because if I open a terminal and look at my env, it shows SHELL=/bin/bash.  <br>
<br>The only other aspect I am aware of is if you run a script that opens with #!/bin/sh, you will be running dash, not bash.<br><br>
