Question 14 papa .1. In this problem, you should write a short bash script. The script should list all files that end in .o from the /lib directory on a UNIX system, only if the file name (not including the extension) begins and ends with a vowel. 2. Write a bash command to print out a text representation of all of the pop assembly instructions from an ELF file named runme.

Consider the following Unix commands and identifies the output of the commands.cp -i file1 file2cp -v file1 file2 Choose an answer A Error. B The -v option provides interactive copying with warning messages and the -i option displays informative messages. C The -v option is used to updates the newly created file to the destination file and -i is used for informative messages. D The -i option provides interactive copying with warning messages and the -v option displays informative messages.
Create File comparators that arrange files in ascending/descending order of file size, ascending/descending order of file name, and ascending/descending order of last modification date. Employ these comparators in LS, a programme that accepts a command-line input and lists the files in the current directory in a certain order, such as "-t" to sort by timestamp.To break ties, support several flags. Be certain you use a reliable sort.
Write a program that performs the following operations according to the input value with Linux Bash Script. [1] Create a file for a given filename and list the generated file in a long format [2] Delete a file for a given filename [3] Copy a file content to another file [4] Listsubdirectories of a current directory recursively [5] Generate the command that finds how many times the "cat" command has been used in your command history so far. [6] Generate the command that writes the file names starting with W in the active directory to the "Files.txt" file. should be solved using Linux Bash Scripting solution code and one/two screenshots for running of program.
)ios::trunc is used for ?a)If the file is opened for output operations and it already existed, no action is taken.b)If the file is opened for output operations and it already existed, its previous content is deleted and replaced by the new one.c)If the file is opened for output operations and it already existed, then a new copy is created.d)None of above
Answer the questions in Linux command 1. Create a single command to read a file called program.c and write a file called unreadable.c, by replacing all newlines and tabs with spaces, and replacing all multiple consecutive spaces with a single space. The result should still be a legal C program but not exactly readable. 2. Write a single shell command line, possibly consisting of multiple commands (separated by semicolons), that will create a file diffs.txt containing a list of all files found in my Documents directory that aren’t also found in yours. Assume your current working directory is your home directory.
Exercise 1: Please create a script that print “Hello, your name.” • Exercise 2: Please create a directory call user_bin, and add it to PATH. Then mv script of Exercise 1 to user_bin. Then run it from your root directory.• Exercise 3: Add a new command call ‘l’ which will perform exact same as ‘ls -a’. • Exercise 4: Create a function call sortFile, which will sort all filenames of current directory. Exercise 6: Could you add one variable in the example, name the variable as greeting, which displays “Hello, my name is xxx xxx” in the body using variable greeting

Provides a logical view for the user and hides the physical implementation d. Manages directory structures and space allocation for each I/O device e. Allows the use of paging scheme in the storage of files. 2. An MS-DOS table that contains the first block of each file on the disk or disk partition. a. Acyclic directory b. NTFS c.

1.Suppose a file has multiple hard links. What happens if one of the hard links is deleted? * a)The link is removed, but the file remains on the disk b)The file is actually removed from the hard disk, along with the other links c)The file is removed from the hard disk, but the other links are not removed d)You get an error message and nothing gets removed 2.The main reason to store attributes of a files with the inodes (instead of managing centrally with a common data structures) is: * a)To be able to keep attributes intact when the files are moved from one physical storage to another. b)The attributes are actually stored in different data structures within the filesystem c)None of the above d)To be able to maintain consistency across all files. The OS need not worry about the attributes.
