+ | ==== 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 | ||
