Lpi LPIC-1 Exam 101, Part 1 of 2, version 5.0 Sample Questions (Q136-Q141):

NEW QUESTION # 136
Which of the following files, located in a user's home directory, contains the Bash history?

Answer: A


NEW QUESTION # 137
Which of the following commands reboots the system when using SysV init? (Choose TWO correct answers.)

Answer: C,E

Explanation:
The shutdown command is used to bring the system down in a safe and controlled way. It can take various options and arguments, such as the time of shutdown, the message to broadcast to users, the halt or reboot mode, etc. The option -r instructs the shutdown command to reboot the system after shutting down. The argument now means to shut down immediately. Therefore, shutdown -r now will reboot the system without delay. The telinit command is used to change the run level of the system. It takes a single argument that specifies the new run level. The run level 6 is reserved for rebooting the system. Therefore, telinit 6 will also reboot the system. The other options are either incorrect or irrelevant. shutdown -r "rebooting" will also reboot the system, but with a delay of one minute and a message to the users. telinit 0 will halt the system, not reboot it. shutdown -k now "rebooting" will only send a warning message to the users, but not actually shut down or reboot the system.

NEW QUESTION # 138
What is true regarding the command
ls > files
if files do not exist?

Answer: A

Explanation:
The command ls > files uses the output redirection operator > to send the output of the ls command to a file named files. If the file does not exist, it will be created and will contain the output of the ls command, which is the list of files and directories in the current working directory. This is explained in the first web search result 1 and the second web search result 2. References: 1: Input Output & Error Redirection in Linux
[Beginner's Guide] 2: Redirections (Bash Reference Manual)


NEW QUESTION # 139
Which of the following command sets the Bash variable named TEST with the content FOO?

Answer: C

Explanation:
Explanation
The correct way to set a Bash variable is to use the syntax variable=value without any spaces around the equal sign. The value can be enclosed in double quotes if it contains spaces or special characters, but it is not mandatory. Therefore, TEST="FOO" will set the Bash variable named TEST with the content FOO. The other options are either invalid or do not perform the desired task. The set command is used to set or unset shell options and positional parameters, not variables. The var command is not a valid Bash command. The TEST =
"FOO" syntax will cause a syntax error because of the spaces around the equal sign. References:

NEW QUESTION # 140
Which of the following commands displays the output of the foo command on the screen and also writes it to a file called /tmp/foodata?

Answer: D

Explanation:
Explanation
This command will display the output of the foo command on the screen and also write it to a file called
/tmp/foodata. The syntax of the command is:
foo | tee [options] [file]
The foo command is any command that produces some output. The | symbol is a pipe operator that redirects the standard output of one command to the standard input of another command. The tee command reads from the standard input and writes to both the standard output and one or more files. The options can modify the behavior of the tee command, such as appending to the file instead of overwriting it, or ignoring interrupt signals. The file is the name of the file to which the output is written. If no file is given, the tee command will only write to the standard output.
Therefore, the command foo | tee /tmp/foodata will run the foo command, pipe its output to the tee command, which will display the output on the screen and write it to the file /tmp/foodata.
The other commands are incorrect for the following reasons:
* A, foo | less /tmp/foodata: This command will not write the output of the foo command to a file, but it will display the output of the foo command on the screen in a pager. The less command is a program that allows the user to view and scroll through a file or the output of a command. The syntax of the command is:
foo | less [options] [file]
The foo command is any command that produces some output. The | symbol is a pipe operator that redirects the standard output of one command to the standard input of another command. The less command reads from the standard input or a file and displays it on the screen in a pager. The options can modify the behavior of the less command, such as setting the number of lines per screen, or searching for a pattern. The file is the name of the file to be viewed. If no file is given, the less command will read from the standard input.
Therefore, the command foo | less /tmp/foodata will run the foo command, pipe its output to the less command, which will display the output on the screen in a pager. However, the /tmp/foodata argument will be ignored by the less command, because it will read from the standard input instead of the file. The command will not write anything to the file /tmp/foodata.
* B, foo | cp /tmp/foodata: This command will not work as expected, because it has several errors. First, the cp command is not a valid command to write the output of a command to a file. The cp command is used to copy files or directories from one location to another. The syntax of the command is:
cp [options] source destination
The options can modify the behavior of the cp command, such as preserving the attributes of the files, or creating backups of the existing files. The source is the name of the file or directory to be copied. The destination is the name of the file or directory where the source is copied to.
Second, the pipe operator is not a valid way to redirect the output of a command to the cp command. The pipe operator redirects the standard output of one command to the standard input of another command. However, the cp command does not read from the standard input, but from the source argument. Therefore, the command foo | cp /tmp/foodata will run the foo command, pipe its output to the cp command, which will ignore the standard input and report an error for missing the destination argument. The command will not write anything to the file /tmp/foodata.
* C, foo > /tmp/foodata: This command will not display the output of the foo command on the screen, but it will write it to a file called /tmp/foodata. The > symbol is a redirection operator that redirects the standard output of a command to a file or device, overwriting any existing content. The syntax of the command is:
foo > file
The foo command is any command that produces some output. The > symbol redirects the standard output of the foo command to the file. The file is the name of the file to which the output is written.
Therefore, the command foo > /tmp/foodata will run the foo command, redirect its output to the file
/tmp/foodata, and overwrite any previous content. The command will not display anything on the screen.
* E, foo > stdout >> /tmp/foodata: This command will not work as expected, because it has several errors.
First, the stdout argument is not a valid file name or device name. The stdout is an abbreviation for the standard output, which is a stream that a program uses to write its output. However, the stdout is not a file or device that can be used as a destination for the redirection operator. Second, the >> symbol is a redirection operator that redirects the standard output of a command to a file or device, appending to any existing content. The syntax of the command is:
foo >> file
The foo command is any command that produces some output. The >> symbol redirects the standard output of the foo command to the file. The file is the name of the file to which the output is appended.
Therefore, the command foo > stdout >> /tmp/foodata will run the foo command, redirect its output to the stdout argument, which will cause an error, and then redirect its output again to the file /tmp/foodata, which will append the output to the file. The command will not display anything on the screen.
