AnyCommand 1> outputFile 2> errorFile
AnyCommand 2> errorFile 1> outputFile
Both of the above commands will work same way in terminal. So, order does not matter.
Addition, > means to overwrite the file, >> can be used if we want to append the output or error to a file.
And also, we can write '1>' as '>' also because '>' by default is '1>'

In Unix/Linux, input and output are treated as files and referenced by the operating system using file descriptors. When you open a shell session, for example, three file descriptors are in use: 0 standard input (stdin) 1 standard output (stdout) 2 standard error (stderr) By default, the command interpreter (shell) reads keyboard input from file descriptor 0 (stdin) and writes output to file descriptor 1 (stdout), which appears on the screen. As you explored in Lab 2, input/output can be...
1 Objective The rules for a new type of programming contest provides a list of problems, their respective score in integer points, and a statistically valid estimate of the time it takes to solve the problem. This duration or time is expressed in integer hours. To help with a solution strategy the contest organizers reveal there is a dynamic programming solution enabling all the contestants to maximize their score - and stay within the time limits for the contest. One...
Copy/Paste your script from 5b here.
4. Let's look at a more complicated script executable. a. Write the following as script6.sh and change its permissions to count for num in d do if num eq 100 then count (count+1) done echo The number 10 was found $count times What is the output? Run the script as ./script6.sh 10 20 30 10 40 20 50 10 60 <enter Summarize what the script does r using the read command. The following script...
Write a c++ program in that file to perform a “Search and Replace All” operation. This operation consists of performing a case-sensitive search for all occurrences of an arbitrary sequence of characters within a file and substituting another arbitrary sequence in place of them. Please note: One of the biggest problems some students have with this exercise occurs simply because they don’t read the command line information in the course document titled “Using the Compiler’s IDE”. Your program: 1. must...

1 Objective Build a hashing algorithm that is suitable for use in a Bloom Filter. Please note that while a cryptographic hash is quite common in many Bloom Filters, the hashing algorithm to be implemented is a mix of the the following algorithmic models, specifically, a multiply & rotate hash colloquially known as a murmur hash, and an AND, rolale, & XOR hash colloquially known as an ARX hash. 2 Requirements • Inputs. Read the input file which contains strings...
using c 3 File Input & Data Processing Reading data from a file is often done in order to process and aggregate it to get ad- ditional results. In this activity you will read in data from a file containing win/loss data from the 2011 Major League Baseball season. Specifically, the file data/mlb_nl_2011.txt contains data about each National League team. Each line contains a team name fol- lowed by the number of wins and number of losses during the 2011...
Write an open_file() and a function that reads a csv data file

Microsoft Word - project09_final_RJE.docx 1/17 This project focuses on analyzing a publicly available dataset containing information about the spread of nCoV. Since this is an active situation, this dataset is constantly being updated with the latest figures. However, for our purposes, we will use a static version of the dataset provided to you with this project (ncov.csv). This static version was lasted updated on...
Y. Daniel Liang’s 8 Class Design Guidelines were posted on the File Manager and handed out in class. Please choose 5 guidelines and discuss them in depth. For each guideline, use 1 page or more for your discussion. You can use the code provided in class to demonstrate your points. The code should not be more than one-third of your writing. 1. Cohesion • [✓] A class should describe a single entity, and all the class operations should logically fit...
