8.3. Running Commands as the lockss User#

Unless otherwise noted, most commands in this manual are intended to be run as the lockss user (oftentimes in the lockss user's lockss-installer directory). This section describes two methods for doing so.

8.3.1. Running Commands as lockss With sudo#

If you are logged in as a user who can run commands as lockss via sudo:

  • You can start a Bash shell session as the lockss user and run any number of commands in it:

    1. Run this command [1]:

      sudo -i -u lockss

      Tip

      You can also use the slightly shorter version sudo -iu lockss.

    2. Run commands as they are listed in the manual, for example scripts/start-lockss --wait.

    3. When you are done, exit the lockss shell session by typing exit or logout or hitting Ctrl + D.

  • Alternatively, you can use sudo to run a single command as the lockss user.

    Add the following in front of the command listed in the manual [1]:

    sudo -u lockss ...

    For example, if the command listed in the manual is scripts/start-lockss --wait, you would type sudo -u lockss scripts/start-lockss --wait.

8.3.2. Running Commands as lockss With su#

If you are logged in as root but your system does not have sudo (or does not let root use sudo), you can use su instead:

  • You can use su to start a Bash shell session as the lockss user and run any number of commands in it:

    1. Type this command:

      su lockss

    2. Run commands as they are listed in the manual, for example scripts/start-lockss --wait.

    3. When you are done, exit the lockss shell session by typing exit or logout or hitting Ctrl + D.

  • Alternatively, you can use su to run a single command as the lockss user:

    Put the command listed in the manual in quotation marks in the following way:

    su -c '...' lockss

    For example, if the command to be run as the lockss user is scripts/start-lockss --wait, you would type su -c 'scripts/start-lockss --wait' lockss.

    Caution

    You will need to take care if the command itself contains quotation marks [2] .
