FLEXlm license manager 2.0 installer may fail using dash

Installation of the new Intel® License Manager for FLEXlm* version 2.0 for Linux* (released Janaury 2012) may fail with syntax errors when being executed under the dash.

Check the /bin/sh link which shell it actually links to, for example

  $ ls -al /bin/sh
  lrwxrwxrwx 1 root root 4 2010-05-27 16:10 /bin/sh -> dash

If it links to the dash (as shown above) you may solve the issue with one of the following:

Solution 1: Link /bin/sh to bash
(at least for the time of installation; requires (sudo) root rights), for example

  # rm /bin/sh
  # ln -s /bin/bash /bin/sh

Solution 2: Replace the Shebang line in the install script
Edit file Intel_INSTALL and
replace
  #!/bin/sh
by 
  #!/bin/bash
