Method 1: Download binaries

Just download compressed executable file of your operating system, and decompress 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 seqkit /usr/local/bin/
    2. Or add the current directory of the executable file to environment variable PATH:

      echo export PATH=\$PATH:\"$(pwd)\" >> ~/.bashrc
      source ~/.bashrc
  2. For windows, just copy seqkit.exe to C:\WINDOWS\system32.

Method 2: Install via conda Install-with-conda Anaconda Cloud downloads

conda install -c bioconda seqkit

Method 3: For Go developer

go get -u


Note: The current version supports Bash only. This should work for *nix systems with Bash installed.


  1. run: seqkit genautocomplete

  2. create and edit ~/.bash_completion file if you don't have it.

    nano ~/.bash_completion

    add the following:

    for bcfile in ~/.bash_completion.d/* ; do
      . $bcfile
