  1. Getting complete lineage for given TaxIds


  1. Download and uncompress taxdump.tar.gz:
  2. Copy names.dmp, nodes.dmp, delnodes.dmp and merged.dmp to data directory: $HOME/.taxonkit, e.g., /home/shenwei/.taxonkit ,
  3. Optionally copy to some other directories, and later you can refer to using flag --data-dir, or environment variable TAXONKIT_DB.

All-in-one command:

wget -c 
tar -zxvf taxdump.tar.gz

mkdir -p $HOME/.taxonkit
cp names.dmp nodes.dmp delnodes.dmp merged.dmp $HOME/.taxonkit

Update dataset: Simply re-download the taxdump files, uncompress and override old ones.


Go to Download Page for more download options and changelogs.

TaxonKit is implemented in Go programming language, executable binary files for most popular operating systems are freely available in release page.

Method 1: Download binaries (latest stable/dev version)

Just download compressed executable file of your operating system, and uncompress it with tar -zxvf *.tar.gz command or other tools. And then:

  1. For Linux-like systems

    1. If you have root privilege simply copy it to /usr/local/bin:

      sudo cp taxonkit /usr/local/bin/
    2. Or copy to anywhere in the environment variable PATH:

      mkdir -p $HOME/bin/; cp taxonkit $HOME/bin/
  2. For Windows, just copy taxonkit.exe to C:\WINDOWS\system32.

Method 2: Install via conda (latest stable version) Install-with-conda Anaconda Cloud downloads

conda install -c bioconda taxonkit

Method 3: Install via homebrew (latest stable version)

brew install brewsci/bio/taxonkit

Method 4: For Go developer (latest stable/dev version)

go get -u


Supported shell: bash|zsh|fish|powershell


# generate completion shell
taxonkit genautocomplete --shell bash

# configure if never did.
# install bash-completion if the "complete" command is not found.
echo "for bcfile in ~/.bash_completion.d/* ; do source \$bcfile; done" >> ~/.bash_completion
echo "source ~/.bash_completion" >> ~/.bashrc


# generate completion shell
taxonkit genautocomplete --shell zsh --file ~/.zfunc/_taxonkit

# configure if never did
echo 'fpath=( ~/.zfunc "${fpath[@]}" )' >> ~/.zshrc
echo "autoload -U compinit; compinit" >> ~/.zshrc


taxonkit genautocomplete --shell fish --file ~/.config/fish/completions/
