 +==== 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 //​revision//​ 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
