Including a semicolon at the end of the line will not affect the text being displayed. d. All of the other options are true. ANSWER: RATIONALE:

All of the options are true. The echo command can be used to display text whether the text is surrounded by quotation marks or not. It will display shell variables by using the $ sign in front of the variable name. It will also execute the command with a semicolon at the end and not affect the text. This is because you can run multiple commands at the command line by separating them with semicolons, but if there is only one command, it just stops after that command.

Options that start with two dashes are called POSIX options and are followed by a word that indicates the task to be performed.

The first argument of the grep command accepts a regular expression, and the second argument accepts the filename. The ^ regular expression matches a word at the beginning of a line, while the square brackets match a single character. Thus, ^42[3-8] would match lines that start with 42 followed by a single character from 3 to 8. The ^ metacharacter must also be protected from shell interpretation using either single quotes, double quotes, or a backslash character.

The square bracket wildcard metacharacters are used to match a single character, and a ! character within these square brackets reverses the match condition. Thus [!27] would match any character except 2 or 7.

POINTS:

When searching for text, you must use regular expressions, and when searching for filenames, you must use wildcard metacharacters. Thus, the first argument of the grep command accepts a regular expression, and the second argument accepts wildcard metacharacters. The ^ regular expression matches a word at the beginning of a line, while the * wildcard matches zero or more characters in a filename. The ^ metacharacter must also be protected from shell interpretation using either single quotes, double quotes, or a backslash character.

The chmod command can be used to set permissions by specifying the exact permissions (r, w, and/or x) for users (u), group (g), and others (o) followed by the filename they are to be set for. The chmod command can be used to set permissions by specifying them in octal format. Read has a value of 4, write has a value of 2, and execute has a value of 1.

certain file. Instead of returning the results she expected, an error message is displayed that it cannot find the plocate.db file in its default location. Which of the following commands should Jean run in an attempt to resolve this problem? a. apt upgrade plocate b. updatedb c. locate --update d. mlocate --update ANSWER: RATIONALE:

The updatedb command is usually run daily by cron to update the default database. However, until it is run for the first time, the locate command will be unable to search an index of the files on the system. This means that it may be necessary to run the updatedb command manually before the locate command can be used for the first time.

Since the root filesystem should not contain most data, it is reasonable to assume that most server systems will contain the minimum of two local storage devices to provide RAID level 1 fault tolerance for the root filesystem. All other data is typically stored on other storage devices or SANs with higher RAID levels for speed and fault tolerance.

The Linux kernel offers different storage schedulers for I/O. If performance issues persist for a storage device, you can try using different schedulers to see if it solves the issue. To use a different scheduler, you must first view the available schedulers in the /sys/block/sdb/queue/scheduler file, and then echo the appropriate one to the file.

The mtr command combines the functionality of the traceroute and ping commands and is also known as My Traceroute. The traceroute command on Linux is fully written out and prints the route packets take to a network host. The tracepath command traces a path to a network host, discovering the MTU along this path.

FTP, running on ports 20 and 21, should be disabled and discarded in favor of SFTP or some other secure method of transferring files. Telnet runs on port 23 and does not use encryption. It is a best practice to disable telnet on most systems. HTTP runs on port 80 and should be disabled in favor of HTTPS on port 443 where possible.

Quota limits, insufficient permissions to the target directory, and target filesystem inode exhaustion are common reasons why a file could not be copied (and created) in a folder on a new filesystem. If the target filesystem was corrupted, the file copy would proceed but the copied file may have corrupted contents following the copy operation.
