POWERSHELL TASK Try to swap two strings/names in a file and the file name should be a command-line argument.
If a file contains an index directory that allows for random access, what does it mean?
The standard library function int fseek(FILE *fp, long offset, int origin) is identical to Iseek except that fp is a file pointer instead of a file descriptor and the return value is an int status, not a position. Write fseek. Make sure that your fseek coordinates properly with the buffering done for the other functions of the library.
Using the Seek() Method in C#In the next steps, you use the Seek() method to reposition a file pointer so you canaccess a file from any location. The user will be prompted to enter a number representinga starting point to list the names in the Names.txt file. Names from that pointforward will be listed, and then the user will be prompted for another selection.1. Start a new program named AccessSomeNames that demonstrates howto access requested names from the Names.txt file you created in theCreateNameFile application.Searching a Sequential Text File using System;using static System.Console;using System.IO;class AccessSomeNames{static void Main(){FileStream file = new FileStream("Names.txt",FileMode.Open, FileAccess.Read);StreamReader reader = new StreamReader(file);
The Directory class has a list of names in it. You should use dynamic memory to create anarray upon instantiation. You should create a copy constructor for the directory class and anassignment operator (i.e. operator=()). You should create a function called fillDirectory whichaccepts a size for the directory and the names for it both of which should be given by the user.In main, create directory1 and fill it with information. Use the assignment operator=() to setdirectory2 equal to directory1. This is in c++
Unix assignment Purpose: The purpose of this assignment is to use various concepts of the C Shell. 0. Change your default login shell to the C Shell. 1. Create a .cshrc file in your home directory that will do the following: * Create the alias (lsall) that will do all of the following: display the date, and a recursive long list of all files in a directory. * Create the alias (whoson) that will display the date and a sorted list of users logged in. * Declare the LOCAL variable that controls the size of your history list to the value 200. * Declare the shell variable that will cause the C Shell to send a message to your terminal whenever one of your background commands complete. 2. Create a .login file in your home directory to do the following. * Declare the GLOBAL Terminal Type variable to the value vt100. Display the value of the variable. Logout and log back in to make sure your .cshrc and .login files are automatically executed. Create a lab8.scr…
Given the variable names pathName contains a string describing a directory path, write a statement that will store the names of all files in a List structure named volume. DO NOT traverse the path/directory. You are only interested in the immediate path. You may assume that any neccesay statments already exist.

PYTHON-Assume you have a file that has two columns separated by a comma. The first column contains gene accession numbers, and the second column contain their nucleotide sequence. For example: ABC123, AAGTCTTCCCTAAGCCC... KHJ456, TTCGGTCATACTATTC... NMG789, GCTACTCGATGCTA.... .... The file can contain any number of rows. Write a program that reads in this file (you can create one to test your code with, use TextEdit or Notepad) and creates a dictionary, where the keys are the accession numbers and the values are the sequences. Print out to the screen the dictionary pairs that you created.
Project 1-UNIX Shell Design a C program that copy the file "input.txt" to "out.txt" using Ubuntu (Linux) system calls. The program will create the directory (~/OS-Project) to store the file "out.txt" inside it. The program will skip m letters at a time. The process of reading will start from the letter of index i. The values of m and i must be provided by the user.
