Step by step
Solved in 2 steps
- 20. Create a linux bash script to get a filename as input and then it should check and display if file exist and size is greater than zero, then should get input of any file comparison operator and then display if the file is true or false for that given file comparison operator. 21. Create a linux bash script to get three numbers as positional parameters then display the greatest and least of the given numbers. If positional parameters are not given then message "This script requires 3 numbers as positional parameters, Try again.." should be displayed.Q4. Develop a shell-script that reads the name of a file from user and prints out if such file exists in the 'pwd' and that if it's a 'file' or a 'directory'.Write a shell script to read your name , output it, and create a file with {your_name }_file.
- Write a program to read two file names from the command line. If the number of arguments in the command line are more than or less than two, then the program should terminate with an appropriate error message. Otherwise, it should open the first file and copy its contents into the second file, in effect overwriting its contents, if any.Answer all questions else downvote question 1. Create a script where you prompt the user for input, and the value provided will be a user. Loop through each file in that user's home directory (ignore the sub directories) and count the number of times a file contains the word ERROR (hint use 'wc' command to help with counting) and output the total number of errors at the end of the script. Once completed, take a screenshot of the source code of the script, and of the script executing, to execute the script you will need to create your own sample input, please include the sample input as part of your execution screenshot. question 2. What would be your current working directory if you changed directories to /log/././././../media/log/ssh/test/../users/ question 3. What would be your current working directory if you changed directories to /opt/test/usr/www/sbin/boot/pdfs/./spool/share/etc/./bin/.././httpd/A client sends you two files containing two shapes to be used in the design of a logo. Your computer could not recognize the format of the files sent in order to display them, so you manually open the files on a text editor, and found the following content within each file: File A File B (-2.5, -2) (0.5, 4) (2.5, 3) (-0.5, -3) START (-3, -2) <√34, 30.964°> <√10, 71.565°> <-5, -3> <-1, -3> Based on this data, name the types of the two shapes, justifying your answer by assessing the properties of each shape, and drawing a small sketch for each.
- PLEASE ANSWER THIS AND DO NOT COPY PASTE ANSWER FROM OTGER SITE.I JEED UNIQUE ANSWERWrite a shell script that, given a file name as the argument will count the number of English language articles: 'A', 'An' and 'The'. Write the results to the file names "results.dat". The input file to be used is "hounds". Shell Script Please if possibleWrite the script that would create file and allow the user to add text in the file. The reading of the text from the user should stop after entering specific character (for example: after entering “/” or user choose Y/N as the command to stop adding the text).
- Implement a simplified version of the UNIX program "cp", which copies one file to another by changing the file permission (specified by the program). Use Low-level File Access functions such as create, open, read, write, close, etc.) toimplement this commandAdd a command to this chapter’s case study program that allows the user to view the contents of a file in the current working directory. When the command is selected, the program should display a list of filenames and a prompt for the name of the file to be viewed. Be sure to include error recovery in the program. If the user enters a filename that does not exist they should be prompted to enter a filename that does exist.Write a program to read two file names from the command line. If the number of arguments in the command line are more than or less than two, then the program should terminate with an appropriate error message. Otherwise, it should append the contents of the second file to the first file.
