systemd-run:tldr:44feb
This command is used to run a command as a systemd transient unit. Here's a breakdown of the different components:
-
sudo
: It is used to execute the subsequent command with administrative/root privileges. -
systemd-run
: It runs the command as a transient unit within the systemd system. Transient units are units that are dynamically created and removed as needed. -
--remain-after-exit
: This flag specifies that the transient unit should not be automatically removed after the command exits. It allows the unit to persist even after the command execution is complete. -
--set-env=${name}=${value}
: This flag is used to set an environment variable within the transient unit. Here,${name}
represents the name of the environment variable, and${value}
represents its value. This allows you to pass specific environment configurations to the command being executed. -
${command}
: This is the main command that you want to execute within the transient unit. It can be any executable or script. -
${argument1 argument2 ---}
: These represent the arguments that you want to pass to the command. They are specified after the command name, separated by spaces. The---
is used as a separator to differentiate between the command and its arguments, ensuring all subsequent arguments are treated as arguments and not options.
Overall, this command executes a given command within a systemd transient unit, allowing you to customize environment variables and specify arguments for the command. The sudo
prefix ensures the command is executed with administrative privileges.
