Top Forums Shell Programming and Scripting How to remove answers and explanation parts from a text file with lots of questions.? Post 303041668 by Neo on Monday 2nd of December 2019 12:16:34 AM
Old 12-02-2019
The problem I have is trying to match multiple lines using sed or egrep, so I did not quickly find a way to filter out the Explanation text. The rest was easy (plus I removed the stray number and the "New questions" phrase):

Code:
sed 's/NO./\nNO./' test.txt |egrep -v '^Answer|^Explanation|^New questions|^[0-9]'

Leaving an incomplete solution because of the requirement for a multiline regex match:

Code:
ubuntu# sed 's/NO./\nNO./' text.txt |egrep -v '^Answer|^Explanation|^New questions|^[0-9]'

NO.13 Darius is analysing IDS logs. During the investigation, he noticed that there was nothing

NO.15 The Open Web Application Security Project (OWASP) is the worldwide not-for-profit
charitable organization focused on improving the security of software. What item is the primary
concern on OWASP's Top Ten Project Most Critical Web Application Security Risks?

IT Certification Guaranteed, The Easy Way!
The top item of the OWASP 2013 OWASP's Top Ten Project Most Critical Web Application Security
Risks is injection.
Injection flaws, such as SQL, OS, and LDAP injection occur when untrusted data is sent to an
interpreter as part of a command or query. The attacker's hostile data can trick the interpreter into
executing unintended commands or accessing data without proper authorization.

NO.16 A recent security audit revealed that there were indeed several occasions that the company's
network was breached. After investigating, you discover that your IDS is not configured properly and
therefore is unable to trigger alarms when needed. What type of alert is the IDS giving?
A. True Positive
B. False Negative
C. False Positive
D. False Positive

NO.17 A Network Administrator was recently promoted to Chief Security Officer at a local university.
One of employee's new responsibilities is to manage the implementation of an RFID card access
system to a new server room on campus. The server room will house student enrollment information
that is securely backed up to an off-site location.
During a meeting with an outside consultant, the Chief Security Officer explains that he is concerned
that the existing security controls have not been designed properly. Currently, the Network
Administrator is responsible for approving and issuing RFID card access to the server room, as well as
reviewing the electronic access logs on a weekly basis.
Which of the following is an issue with the situation?
A. Segregation of duties
B. Undue influence
C. Lack of experience
D. Inadequate disaster recovery plan

In practice, I would do this in PERL or PHP because of the required multiline matches; but I'm sure someone else can do a much better command line than me.

XChangePointerControl() 												   XChangePointerControl()

Name
  XChangePointerControl - change the pointer preferences.

Synopsis
  XChangePointerControl(display, do_accel, do_threshold, accel_numerator, accel_denominator, threshold)
	Display *display;
	Bool do_accel, do_threshold;
	int accel_numerator, accel_denominator;
	int threshold;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  do_accel  Specifies  a  boolean  value that controls whether the values for the accel_numerator or accel_denominator are set.  You can pass
	    one of these constants:  True or False.

  do_threshold
	    Specifies a boolean value that controls whether the value for the threshold is set.  You can pass one of these  constants:	 True
	    or False.

  accel_numerator
	    Specifies the numerator for the acceleration multiplier.

  accel_denominator
	    Specifies the denominator for the acceleration multiplier.

  threshold Specifies the acceleration threshold.  True or False.

Description
  XChangePointerControl()  defines  how  the  pointing	device functions.  The acceleration is a fraction (accel_numerator/accel_denominator)
  which specifies how many times faster than normal the sprite on the screen moves for a given pointer movement.  Acceleration	takes  effect
  only	when  a  particular  pointer motion is greater than threshold pixels at once, and only applies to the motion beyond threshold pixels.
  The values for do_accel and do_threshold must be True for the pointer values to be set; otherwise, the parameters will be unchanged.	 Set-
  ting any of the last three arguments to -1 restores the default for that argument.

  The fraction may be rounded arbitrarily by the server.

Errors
  BadValue  accel_denominator is 0.
	    Negative value for do_accel or do_threshold.
