Write a shell script wparser.bash that would process these data files. The shell script is expected to be given the name of a directory, under which it will start the search for data files whose names are of the form weather_info_*.data as its argument. (Do not hard code the directory name in your script). If the script is not invoked with the correct number of arguments, it should throw an usage message and terminate with a code of 1. If the passed argument is not a valid directory name, it should throw an error message and terminate with code 1. For this particular situation (and only here), the error message must be send to the standard error and not the standard output.

Bash Shell Scripting – Misc. Commands Create a bash script ~/test4.sh with any text editor. Write a bash script that does the following: echo "File Name: $0" echo "First Parameter : $1" echo "Second Parameter : $2" echo "Quoted Values: $@" echo "Quoted Values: $*" echo "Total Number of Parameters : $#" Take a screenshot of the console output. Run your scripts after doing a chmod 777 on the script. Open a terminal window and run the following commands: which gcc man gcc
Use the Bash shell for the completion of this project. Develop a shell scripting application that allows the user to perform some advanced mathematical operations. Your application should allow the user to perform these tasks: Task 1: Find the even multiples of any number chosen by the user in a given range – the user should specify the multiples of which number they want to print and a minimum and maximum value. The multiples printed should be within the [minimum, maximum] range. For example, if the user chooses the number 7 and would like to print all even multiples in the [15, 60] range, the program should print all the even multiples that are bigger than or equal to 15 (minimum), but smaller than or equal to 60 (maximum). The program should keep a count of how many numbers were printed and should output that count, as well as the numbers. The output then, for the example given, should be 28, 42, 56, and the count should be 3.
Given a directory called Project1 with 500 files called rock000.py, rock001.py, ... , rock500.py, create a bash shell script that will rename all the files given in this directory. The script should take two arguments: a base name and a file extension. Please include the specifics from the example in the code (i.e., identify the base name, extension, and old and new file names and write them as part of the code). If we run bash project.sh project_rocks py the resulting files in the directory should be like this: project_rocks000.py, project_rocks001.py, .. , project_rocks500.py.
Write a function extractData in your shell script wparser.bash. This function will perform the core processing logic associated with each file. The main script will just iteratively call this function with different files as its argument. This function should accept a data file as its argument. This function should then produce an output of the following format that that contains only the temperature and wind information from the sensors along with a header. (see image; truncated for brevity). A clean format of data like this form can be used by various information processing systems. The script is basically only including the year, month, day and hour information, followed by the temperature reported by each temperature sensor, and wind speed from wind sensors at that time. If a temperature sensor’s reading is NOINF or MISSED SYNC STEP in the original data file for that particular time, the script must instead output the previous readout for that temperature sensor.

In this question, you will develop your own version of shell. Your shell will execute commands given bythe user. The steps involved will be as follows:1. User types a command, such as “cp ./OS ../newOS”. The command will be stored in a characterarray or a string object.2. Shell will perform tokenization and separate the command and its arguments.3. Shell will create a child process and use execvp system call to execute the command.4. Shell will wait for the command to finish execution.5. After the command has been executed, shell will ask the user to enter the command again.6. Shell will exit when the command given by the user is “exit”. 7. The command can have any number of | symbols, such ascommand1 | command 2 | command3 > file.txt

Write a shell script that reads a file name and checks this file exists or not. If the file exists, searches this file for "Joshua" or "joshua" and displays the total number of occurrences of "Joshua" and "joshua"; if the file does not exists, display "the file does not exist." Hints: you can use cat and egrep.

A client with a completed main function is provided. The main function should not be modified. You must update the client by creating and implementing the various functions described below. readFile – Loads the parameter array with Billionaire objects. The data for each Billionaire is read from the given data file which is in CSV format (comma delimited - 1 line per record with fields separated by a comma.) The function should read each line from the file, pass the line read to the Billionaire class constructor and store the resulting object in the parameter array. The second parameter represents the maximum number of Billionaire objects that can be stored. displayAll - Displays a list of the Billionaires stored in the array. getRange – Determines the smallest wealth value and the largest wealth value within the array. These values are returned to the caller via reference parameters. getWealthiest – Returns the Billionaire within the array with the greatest wealth. getUS –…
The delivery drones have a internal reporting and logging system thatrecords events and issues during flights. These logfiles contain the last 1000events/messages as well as their status codes.The Logfile FormatBy default, the logfiles are all called ‘logfile.txt’. Each logfile is exactly 1000 lineslong.Each entry in the file consists of 4 fields:1. a line number (starting at 0)2. a POSIX timestamp3. a message/event type4. an event descriptionEach field (line number, timestamp etc.) is separated by a space, except for thedescription which ends with a full stop.Log events come in three different types: NOTIFY, WARNING, and ERROR. Task 1: Display Because the logfiles are so big, we would only like to display a certain number oflines at a time. We prompt the user to choose start and end line numbers andprint all the lines from start to end (inclusive).The input constraints are as follows: 0 start end 999You can safely assume that the inputs will fall within that…
