| * If you know that you are going to use UV-CDAT, you might as well use the ''conda'' from //Miniconda// to avoid uselessly duplicating packages downloaded from the official Anaconda repository (used by Anaconda) with the same packages downloaded from the conda-forge repository (used by UV-CDAT). | * If you know that you are going to use UV-CDAT, you might as well use the ''conda'' from //Miniconda// to avoid uselessly duplicating packages downloaded from the official Anaconda repository (used by Anaconda) with the same packages downloaded from the conda-forge repository (used by UV-CDAT). |

| | ==== Installation history ==== |
| | |
| | You can get the current list of installed packages with ''conda list'', but it may also be useful to know the installation order: |
| | |
| | * ''conda list %%--%%revisions'' revisions will display **exactly** what was installed and when (including the updates, and automatic dependencies installation) |
| | * You can theoretically roll back to a previous ''RR'' //revision// number with: ''conda install %%--%%revision RR'' |
| | * There is more information in the ''conda-meta/history'' installation log files. e.g., if you need to know the list of installation commands used:\\ <code> $ egrep -e 'cmd:' -e '==>' /home/share/unix_files/cdat/miniconda3/envs/cdatm18_py2/conda-meta/history |
