- Linux commands: In this part of the lab, you will run Linux commands, capture their output in a format that shows the command and its results in an easy way (command-> new line-> output - > new line-> new line-> command, .... etc). In your output file, make sure to print out the name of your user account and todays date. It should look something like this "My Student Account is " , "Todays Date is ". Can someone please help with this ?Note that lastlog file in /var/log is not a text file, to view the file use lastlog command linux redhat command only plsUse Linux executable objectCode5 for this question. These files are on syccuxas01.pcc.edu in directory ~michael.trigoboff/cs201/quiz02LinuxFiles. The file is run from the Linux command line, and takes one positive numerical argument, like this: ./objectCode5 3 (You can enter any small positive integer instead of 3.) Command line arguments are passed to int main(int argc, char** argv) as arguments argc and argv. You should assume that argc is at ebp+8 and argv is at ebp+12. This code contains a function named what. Using gdb, figure out what the function named what computes: Question options: 1) the absolute value of n 2) n squared 3) the sum of the integers from 1 through n 4) factorial of n

- Hello! I have an assignment for my linux class and I am having some difficulty with the last question which was a challenge to me: Here is the last bit of homework CHALLENGE: Your job is to create a booklet (i.e. a printable file) that contains the name of every header file on the system followed by a 1-line description of the purpose of that file. (Hint: the first line of the .h file has a description). Each file name and description set should be followed by a blank line before the next file name entry in this file. Example file entry: (shown on picture attached) I am really desperate as I have tried everything it doesn't seem to go through.We will use the file classlist.txt. Note that it contains a list of usernames. 3. Write a script called finduser that is to be called as follows, where classlist is the name of the classlist file, and username is a particular student's username, either first name or last time. ./finduser classlist username The script should check that the correct number of arguments was received and print an error message if not, check whether the classlist file exists and print an error message if not, print the line of the given username in the classlist file If you have not been doing so all along, you should now add some comments to your script and thoroughly test it! 4. Write the script into your lab report.We can create a new text file with the following commands, except: Group of answer choices TYPE ECHO with > FSUTIL FILE CREATENEW NUL >
