Installing SeaDAS with sudo or not?

by testth » Thu Jan 12, 2017 8:32 am America/New_York

Hello,
I want to install SeaDAS 7.3.2 under Ubuntu. Should I install it with "root" privileges using the "sudo" command into /opt/seadas_7.3.2 or should I install it from a normal user login into /home/seadas_7.3.2?
Regards

It is better to install SeaDAS as a normal user in your home directory or a dir that you have write privileges for.  I usually install it in

/home/<user>/local/seadas7.3.2

There will be issues with permissions if you install as root.

The general principle is that sudo should only be used when absolutely necessary.  SeaDAS works fine when installed without sudo.

Are you hoping to share one Seadas 7 install among multiple users?   That is generally not a good idea -- the GUI needs a lot of resources so multiple users will bog down, and since SeaDAS 7 is not generally used that way there may be conflicts waiting to be discovered by your users.  You should install SeaDAS separately for each user in /home/<user_N>/seadas_7.3.2, where <user_N> is replaced by your actual username,  from your normal user login.  If you are doing installs for multiple users you can use sudo --user=<user_N> to do the install as if you were <user_N>.   If there is limited space in the user home directories, you can install SeaDAS to a disk partition that has more space.  For most people, the space needed for SeaDAS 7 is much smaller than the space needed for the data being used with SeaDAS, so there is usually no problem finding space for multiple SeaDAS installs.

Yes, I hoped to install SeaDAS only one time and to share it for multiple users. Now I learned it is better to install SeaDAS for each user.
Thanks for the help.
