Standardmäßig wird der Inhalt des Verzeichnisses in das Ausgangsverzeichnis eines neuen Benutzers kopiert, wenn das Konto erstellt wird, indem die Option -m an den Befehl useradd übergeben wird. (Geben Sie den vollständigen Pfad zum Verzeichnis an.)
정답:
etcskel
Explanation:
The /etc/skel directory contains files and directories that are used as a template for creating a new user's home directory. The useradd command uses the -m (or --create-home) option to create the user home directory as /home/username and copy the files from /etc/skel to it. The files in /etc/skel are typically initialization files such as .bashrc, .profile, and .bash_logout that set the user's environment variables, aliases, and other preferences. The system administrator can customize the /etc/skel directory to provide a consistent and convenient initial setup for new users. Reference:

Welcher in systemd enthaltene Befehl unterstützt die Auswahl von Nachrichten aus dem systemd-Journal nach Kriterien wie Zeit oder Einheitenname? (Geben Sie nur den Befehl ohne Pfad oder Parameter an.)
정답:
journalctl
Explanation:
The command journalctl is included in systemd and supports selecting messages from the systemd journal by criteria such as time or unit name. The systemd journal is a binary log file that stores system and service messages. The journalctl command can be used to view, filter, export, and manipulate the journal entries. For example, to show all messages from a specific unit, such as sshd.service, the command would be:
journalctl -u sshd.service
To show all messages from a specific time range, such as yesterday, the command would be:
journalctl --since=yesterday
The journalctl command has many options and arguments that can be used to customize the output and perform various operations on the journal. For more information, see the man page of journalctl or the official documentation1. Reference: [LPI 102-500 Exam Objectives], Topic 106.2: System logging, Weight: 3. [systemd-journald.service(8) - systemd - Debian unstable - Debian Manpages], Section NAME.

Welcher Befehl zeigt alle in der aktuellen Shell definierten Aliase an? (Geben Sie den Befehl ohne Pfadangabe an.)
정답:
aliasaliasp
Explanation:
The alias command is used to create, list, or remove aliases in the current shell. An alias is a short name that refers to another command, usually with some options or arguments. Aliases are useful for saving typing time, avoiding spelling errors, or customizing the behavior of commands. To list all the aliases defined in the current shell, we can use the alias command without any arguments. This will print the aliases in the format of alias name='command'123. For example:
$ alias alias cp='cp -i' alias l='ls -CF' alias la='ls -A' alias ll='ls -alF' alias mv='mv -i' alias rm='rm -i' The output shows that some common commands, such as cp, mv, and rm, have aliases that add the -i option, which prompts the user before overwriting or deleting files. The l, la, and ll aliases are shortcuts for different variations of the ls command, which lists files and directories123.
