The lsup Command

The lsup command is a simple way to update LiteSpeed Web Server from the command line, allowing the possibility of upgrading hordes of LSWS installations with a single command.


The lsup command is located at $SERVER_ROOT/admin/misc/ For my installation of LSWS, the command was thus:



Running the basic lsup command will automatically upgrade your installation of LiteSpeed Web Server to the latest release. There are also options for customizing the command listed below.


  • -f: If you already have the version to be installed, the basic lsup command will abort. The -f option forces lsup to install even if the version you have is the same version as the LSWS to be installed. This can be useful if there has been a change in the build since you upgraded, but a new build has not yet been released.
  • -v: You can control what version you install with the -v option followed by a version number. (For example: ./ -v 4.2.2) This will allow you to downgrade to older versions if you run into a bug. Keep in mind, LiteSpeed only keeps the most recent few versions available. Much older versions are not available.
