The LPI 101 Certification Practice test has the following problems that need fixing:
- 2.4/3/1 is missing the required exhibit.
- 1.3/2/3 shows the answer is D, which is wrong; the answer is A. Running choice D results in an error — ‘cut -b 0-5′ is impossible because bytes start at 1, not 0.
- 2.4/1/2 shows the answer is A, which is wrong; the answer is AC. ‘mkfs -t ext2 /dev/hda4′ will format the 4th partition of the first IDE hard disk just fine.
- 1.8/1/1 shows the answer is C, which seems wrong; the ‘apropos’ and ‘whatis’ programs search the same information, so the answer should be CD.
- 2.11/2/2 shows the answer is D, which is wrong; the answer is C. The ‘/etc/skel’ directory contains files that will be copied to a newly created user directory.
The command ‘ps -A’ displays an ordered list of all running processes, with the right-justifed process ID in the first space-separated field. Suppose you would like to display to screen a list of the five most recently launched processes (those with the highest process IDs). Which of the following commands will display the desired items?
*
A. ps -A | tail -5 | cut -f 1 -d ” ”
*
B. ps -A | tail -5 | sed ’s/[ ]*[0-9]*//’
*
C. ps -A | head -5 | nl
*
D. ps -A | tac | head -5 | cut -b 0-5
The answer to this question according to the test is D. But accroding to the command line output “cut: fields and positions are numbered from 1″ so the correct answer would be
ps -A | tac | head -5 | cut -b 1-5 not 0-5
