command - Executes a command on a remote node¶

Synopsis¶

• The command module takes the command name followed by a list of space-delimited arguments.
• The given command will be executed on all selected nodes. It will not be processed through the shell, so variables like $HOME and operations like "<", ">", "|", ";" and "&" will not work (use the shell module if you need these features).
• For Windows targets, use the win_command module instead.

Options¶

Examples¶

- name: return motd to registered var
  command: cat /etc/motd
  register: mymotd

- name: Run the command if the specified file does not exist.
  command: /usr/bin/make_database.sh arg1 arg2 creates=/path/to/database

# You can also use the 'args' form to provide the options.
- name: This command will change the working directory to somedir/ and will only run when /path/to/database doesn't exist.
  command: /usr/bin/make_database.sh arg1 arg2
  args:
    chdir: somedir/
    creates: /path/to/database

- name: safely use templated variable to run command. Always use the quote filter to avoid injection issues.
  command: cat {{ myfile|quote }}
  register: myoutput
