Regarding the command: nice -5 /usr/bin/prog Which of the following statements is correct?. /usr/bin/prog is executed with a nice level of -5. /usr/bin/prog is executed with a nice level of 5. /usr/bin/prog is executed with a priority of -5. /usr/bin/prog is executed with a priority of 5.

The destination file must be mentioned before the command to ensure redirection. The command sed did not match anything in that file therefore the output is empty. When the shell establishes the redirection it overwrites the target file before the redirected command starts and opens it for reading. Redirection for shell commands do not work using the > character. It only works using the | character instead.

Which of the following statements is correct regarding the command foo 1> bar?. The stdout from the command foo is appended to the file bar. The stdout from the command foo overwrites the file bar. The command foo receives its stdin from the file bar. The command foo receives its stdin from the stdout of the command bar. The stderr from the command foo is saved to the file bar.

After moving data to a new filesystem, how can the former path of the data be kept intact in order to avoid reconfiguration of existing applications? (Choose TWO correct answers). By creating an ACL redirection from the old to the new path of the data. By creating a hard link from the old to the new path of the data. By creating a symbolic link from the old to the new path of the data. By running the command touch on the old path. By mounting the new filesystem on the original path of the data.

Creating a hard link to an ordinary file returns an error. What could be the reason for this?. The source file is hidden. The source file is read-only. The source file is a shell script. The source file is already a hard link. The source and the target are on different filesystems.

It opens an editor with root privileges and loads /etc/fstab for editing. It ensures that all file systems listed with the option auto in /etc/fstab are mounted. It ensures that all file systems listed in /etc/fstab are mounted regardless of their options.

What does the command mount -a do?. It mounts all available filesystems onto the current directory. It shows all mounted filesystems. It mounts all user mountable filesystems for the current user. It mounts all filesystems listed in /etc/fstab which have the option auto set. It mounts all filesystems listed in /etc/fstab which have the option noauto not set.

What is the purpose of the Filesystem Hierarchy Standard?. It is a security model used to ensure files are organized according to their permissions and accessibility. It provides unified tools to create, maintain and manage multiple filesystems in a common way. It defines a common internal structure of inodes for all compliant filesystems. It is a distribution neutral description of locations of files and directories.
