The command "dkms install -m ${acpi_call} -v ${1-2-1}" is used to install a DKMS (Dynamic Kernel Module Support) module with a specific version.

Here's the breakdown of each component in the command:

• "dkms" is the command-line tool for managing DKMS modules.
• "install" is the action performed by the dkms command.
• "-m ${acpi_call}" specifies the module name to be installed. The value of ${acpi_call} is substituted in place of the variable, which represents the desired module.
• "-v ${1-2-1}" indicates the version of the module to be installed. The value of ${1-2-1} is substituted in place of the variable, which represents the desired version of the module.

In summary, the command installs a DKMS module with the specified name (${acpi_call}) and version (${1-2-1}). The actual values for the module name and version would need to be provided when running the command.
