conda info
Update conda to the current version
conda update conda
Install a package included in Anaconda
conda install PACKAGENAME
Run a package after install, example Spyder*
spyder
Update any installed program
conda update PACKAGENAME
COMMANDNAME –help
Command line help
conda install –help
*Must be installed and have a deployable command,
usually PACKAGENAME
Using environments
Create a new environment named py35, install Python 3.5
conda create –name py35 python=3.5
Activate the new environment to use it
WINDOWS:
activate py35
LINUX, macOS: source activate py35
conda env list
Get a list of all my environments, active
environment is shown with *
Make exact copy of an environment
conda create –clone py35 –name py35-2
List all packages and versions installed in active environment
conda list
List the history of each change to the current environment
conda list –revisions
Restore environment to a previous revision
conda install –revision 2
Save environment to a text file
conda list –explicit > bio-env.txt
Delete an environment and everything in it
conda env remove –name bio-env
WINDOWS: deactivate
Deactivate the current environment
macOS, LINUX: source deactivate
Create environment from a text file
conda env create –file bio-env.txt
conda create –name bio-env biopython
