For Linux, everything is considered a file, including regular files, directories and hardware devices. In this question, you are asked to carry out some practical activities to manipulate files using Linux. Include output from the command line to document your answers. a.Describe what this command does: tr <input.txt "[:punct:]" " " | tr "[:space:]" "\n" >temp.txt b. Use the file temp.txt you created in the previous step. Using the command line, sort this, remove duplicate lines, and save the result in output.txt. Can you describe what this file now contains?
Below is a sequence of shell commands that we typed into a bash terminal window on a Linux machine and some of the output that was produced. Your job is to write the output produced by the commands in the sequence. The commands are executed consecutively and changes made by one command may affect the output produced by later commands. First Create a Directory and Rename as Name_AridNo like (Ali_18-Arid-102) and then execute the following commands and show output. Shell > pwd /home/me/test > ls -F hw1 hw1.bak tmp/ > bash > touch it > cd tmp > ls –F justme.txt > echo “Dear Ali” > diary > cat ‘Name_AridNo’ /etc/hosts > pwd
Write a Linux shell script that finds all files on /home that contain a given specific text string in the body of the file,Ensure that the text string your script will search for is supplied at the script’s command line.• Note that your script should handle any error conditions by printing out a descriptive errormessage to the shell and then exiting.• Submit your script with the filename <YourFullName>_restrictfiles.sh. Please submit a screen shot of your work in nano
What does >> accomplish when entered on the command line after a command?a. It redirects both Standard Error and Standard Output to the same location.b. It does not accomplish anything.c. It redirects Standard Error and Standard Input to the same location.d. It appends Standard Output to a file.
For example, if you create a file named: "users.txt" that contains these user names: daniel moshe yossy gabi ran bijo baruch bibi The following command run in an elevated command prompt will parse this file, and create a new user on your computer FOR /F %i in (users.txt) DO NET USER %i P@ssw0rd /ADD With two (2) other options that you specify for each user when they are added?
I created a nano myfile.txt for the input file and it still doesn't work but you can see here that it is in the same directory at the very end and I am still getting the same issue.

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.
Implement a simple version of the linux grep command in C++. grep - Looks through a file, line by line, trying to find a user-specified search term in the line. If a line has the word within it, the line is printed out, otherwise it is not. Use the system calls open(), getline(), close(). Requirements (examples run from. terminal) Your program grep is always passed a search term and zero or more files to grep through (thus, more than one is possible). It should go through each line and see if the search term is in it; if so, the line should be printed, and if not, the line should be skipped. [terminal]$ ./grep ! main.cpp main2.cppcout << "Hello, World!";cout << "Programming is great fun!"; The matching is case sensitive. Thus, if searching for world, lines with World will not match. Lines can be arbitrarily long (that is, you may see many many characters before you encounter a newline character, \n). grep should work as expected even with very long lines. For this,…
What is wrong with the following command string: ls /etc/hosts>listofhostfile ?a. Nothing is wrong with the command.b. The file descriptor was not declared; unless 1 for standard output or 2 for standarderror is indicated, the command will fail.c. The ls command is one of the commands that cannot be used with redirection.You must use | to pipe instead.d. The file listofhostfile will always only contain standard error because a file descriptorwas not declared.
Suppose we want to change the permissions of a file named newfile. a) What user(s) can change the permissions of newfile? b) How do we view what permissions are currently in place for that file? c) What are the base file and directory permissions in most Debian Linux systems? d) What permissions does the preconfigured umask set for new files and directories?
You work for a small company that keeps the following information about its clients:• first name• last name• a 5-digit user code assigned by your company.The information is stored in a file clients.txt with the information for each client on one line(last name first), with commas between the parts. For exampleJones, Sally,00345Lin ,Nenya,00548Fule,A,00000Smythe , Mary Ann , 00012Your job is to create a program assign usernames for a login system.First: write a function named get_parts(string) that will that will receive as its arguments astring with the client data for one client, for example “Lin ,Nenya,00548”, and return theseparate first name, last name, and client code. You should remove any extra whitespace from thebeginning and newlines from the end of the parts.You’ll need to use some of the string methods that we covered in this lessonYou can test your function by with a main() that is just the function call with the argument typed in.Second: write a function make_user(param)…
In many cases you will likely get better information by simply looking closely at the output you got when trying out the command in the other window. What command could you use to list the files in your fileAsst directory, using an absolute path to the fileAsst directory as part of your command? What command could you use to list the text files (only) in your fileAsst directory, using a relative path to the fileAsstdirectory as part of your command? The /usr/include directory contains a large number of C/C++ header files (all ending with a .h extension). What command would you give to list the names of the header files in that directory that include the string “it” as part of the name? One of the files you should now have in your fileAsst directory is TweedleDee/hatter.txt. Suppose that you wished to copy that file into your current (commandsAsst) directory. What command would you give to make that copy? For this, and for the following questions, You will want to delete all…
