Download Page

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)Link

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

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/
```
For windows, just copy taxonkit.exe to C:\WINDOWS\system32.

Method 2: Install via conda (latest stable version) Link

conda install -c bioconda taxonkit

Method 3: Install via homebrew (may not the lastest version)Link

brew install brewsci/bio/taxonkit

Method 4: Compile from source (latest stable/dev version)Link

Install go

wget https://go.dev/dl/go1.24.1.linux-amd64.tar.gz

tar -zxf go1.24.1.linux-amd64.tar.gz -C $HOME/

# or 
#   echo "export PATH=$PATH:$HOME/go/bin" >> ~/.bashrc
#   source ~/.bashrc
export PATH=$PATH:$HOME/go/bin

Compile TaxonKit

# ------------- the latest stable version -------------

go get -v -u github.com/shenwei356/taxonkit/taxonkit

# The executable binary file is located in:
#   ~/go/bin/taxonkit
# You can also move it to anywhere in the $PATH
mkdir -p $HOME/bin
cp ~/go/bin/taxonkit $HOME/bin/

# --------------- the development version --------------

git clone https://github.com/shenwei356/taxonkit
cd taxonkit/taxonkit/
go build

# The executable binary file is located in:
#   ./taxonkit
# You can also move it to anywhere in the $PATH
mkdir -p $HOME/bin
cp ./taxonkit $HOME/bin/

Bash-completionLink

Supported shell: bash|zsh|fish|powershell

Bash:

# 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

Zsh:

# 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

fish:

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

DatasetLink

Download and uncompress taxdump.tar.gz: ftp://ftp.ncbi.nih.gov/pub/taxonomy/taxdump.tar.gz
Copy names.dmp, nodes.dmp, delnodes.dmp and merged.dmp to data directory: $HOME/.taxonkit, e.g., /home/shenwei/.taxonkit ,
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 ftp://ftp.ncbi.nih.gov/pub/taxonomy/taxdump.tar.gz 
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.
