   The output from the command should be:
   bad8ece2ebe47b3e74ced8d91bf7eb0bf102155afc0a18ea9de4477b4ec8429a gensys-2303_230331_amd64.deb
4. Unpack the deb-file with command:
   sudo gdebi gensys-2303_230331_amd64.deb 2>&1 | tee -a /tmp/gdebi.out
5. Contact "info@gensys.se" to get a link to a valid license file for your installation.
   Start webbrowser firefox in the virtual machine.
   Enter the link received from "info@gensys.se"
   Save the license file in directory "/opt/gensys/gensys-2303/bin".
   Make sure file "/opt/gensys/gensys-2303/bin/gen_processor_ID_check" has execute permissions.
6. Create following initialization files:
   

   ~/.profile_gensys            Adds "/opt/gensys/gensys.2303/bin" to $PATH
   ~/.octaverc                  Adds "/opt/gensys/gensys.2303/m" to Octave search path
   ~/Desktop/genfile.desktop    Background icon for launching filemanager "genfile"
   ~/Desktop/genterm.desktop    Background icon for launching terminal "genterm"
   

7. In the end of file "~/.profile" add the following line:
   

   test -f ~/.profile_gensys && . ~/.profile_gensys
   

8. Log out and in again to make the changes to take effect.

Download and uncompress the documentation and the verification examples

• Create a directory where you want to keep Gensys documentation files and verification examples. E.g.; "~/gensys"
• In the newly created work directory. Also create a directory where you want to keep your own work files.
  E.g.: "~/gensys/analyze"
• In directory "~/gensys" download the following files:

  free_models-2301.7z    = Free vehicle models
  homepage-2301.7z       = Documentation and tutorials
  verif-2301.7z          = Verification directory
  

  Webpage mega.nz requires a webbrowser that handles HTML5 and allows JavaScript to create and write to files. Currently Chrome and Firefox works best.
  Also make sure that no firewall prevents you from downloading files from the Internet.
  
  The SHA256 message digest algorithm should give you the following output:

  ec00a0676f1475ad6d416b67e13e771a51494886678ccfe3706df6b4ca58915a  free_models-2301.7z
  e464fe7ffa0ff80de930ea86ddcad3904ac68404be1ad8491594a90d92a2c6ec  homepage-2301.7z
  fd87572e0d809aaa1b3806f624320dfafe36422fabefb95554f23c35a90a25ab  verif-2301.7z
  

  The above output can be created with the following commands:
  

  UNIX:	sha256sum [a-z]*7z
  Windows:	certutil.exe -hashfile free_models-2301.7z SHA256 certutil.exe -hashfile homepage-2301.7z SHA256 certutil.exe -hashfile verif-2301.7z SHA256

• Move the downloaded files to the location which you created under item 1 above.
  Uncompress the files with program "7z" which can be found in package "p7zip-full".
• File ~/.profile_gensys defines two environment variables: $genhomepage and $genverif.
  Environment variable $genhomepage shall point to the location where the Gensys documentation "homepage" is located.
  Environment variable $genverif shall point to the location where the verification examples "verif" are located.
  The directory free_models can be stored anywhere. Use this directory to copy examples from.
  
• The files free_models-2301.7z, homepage-2301.7z and verif-2301.7z can now be removed.

Updates in the new machine

Gen_calclib

1. Default value of wlog_store is changed from 1 to 0. I.e. no printing of log-file as default.
2. Command func rolling_fatigue_3 has been updated so any kind of wear estimations can be used.
3. In command func intpl_track_irr2 and func intpl_track_irr3. Check that the trax-file only contains valid characters: ' \t,+-0123456789.EeDd'
4. In command func intpl_track_irr2 and func intpl_track_irr3. Also add a ramp in the end of the track. To also make a smooth start when the vehicle runs with a negative speed, starting from the end of the track.
5. New beam model coupl beam_4 which takes more effects into consideration than coupl beam_3. Coupl beam_4 is suitable for making models of catenary systems.
6. Two new wheel/rail-coupling elements based on the FaStrip theory developed by Matin Shahzamanian Sichani KTH Stockholm, Sweden. The names of the two new couplings are coupl creep_fastrip_1 and coupl creep_fastrip_3.

Kpf

1. New command "octave_file" which writes stdout to an external file, and the output is formatted as a .m-file.
2. Accept the key-word $ident when creating external files.
3. Calculate and printout height of a potential false flange. The false flange is denoted with the variables "Thl" and "Thr".
4. Rename the Flange thickness variables from Tl & Tr to Sdl & Sdr.
5. Rename the Flange height variables from Fhl & Fhr to Shl & Shr.

Track

1. New program trc_cdf which calculates the Cumulative Distribution Function and Relative Frequency Function of a track irregularity file.

Nedit and pri

1. Handle file that are written in UTF-8 format.
2. Two new scripts "conv_ISO-8859_to_UTF-8" and "conv_UTF-8_to_ISO-8859" which translates in between UTF-8 and ISO-8859 formatted files.

4. gencd
   Go to frequently used directories

New script in $gensys/m

1. GIPr_sum.m
   Calculate GIPr of all rail profiles in a directory structure.
2. GIPw_sum.m
   Calculate GIPw of all wheel profiles in a directory structure.
3. cdf.m
   Calculate Cumulative Distribution Function and Relative Frequency Distribution Function of values stored in a vector.
