Enter a BASH "glob" pattern that will match all files in the current working directory that have an 'm' in their name (start, middle, or end). Note: no "whitespace" is permitted (spaces, tabs, newlines, etc). The answer is one "word" only.
In this assignment you will be writing several functions that process files and dictionaries to encryptand decrypt messages. A dictionary will be used to create a random substitution cypher. Each letterof the alphabet will be mapped to another random letter in the alphabet. No letter will map or bemapped to any duplicate letter. For example given the partial dictionary below you can encrypt amessage.Be sure to use the starter file provided so you can see the appropriate outputs. Be sure to downloadand place the appropriate text files in the same directory as your python file. You only need to submityour python file.Partial Dictionary: {d : a, e: f, h : b, l : p, l : e, o : j, r: m, w: i}originalMessage = “hello world” → encryptedMessage = “bfeej ijmea” Part 1 - Encrypt a Message: You will write 2 functions to build a dictionary and encrypt a messageFunction buildCypher() → dict:This function is to build a dictionary that can be used to create a random substitution cypher.

1. In an earlier assignment, you created a fileAsst directory containing several files. Give a command that will create a file named listing.dat, in your current (commandsAsst) directory, containing a list of the names of all the files in your fileAsst directory. The listing must not include dates, file sizes, or any information other than the names. 2. Someone has decided that the function sequentialInsert, declared in -cs252/Assignments/commandsAsst/project/arrayops.h, should be renamed orderedInsertion. Give a command to produce the altered version the header file, saving it as ~/UnixCourse/commandsAsst/arrayops.h (Something to think about: Why would the same approach not work well for changing the variable name i to i0?) 3. Sometimes programmers propose changes to an existing software definition and need to know what other code could be affected by the change. Suppose that you are a programmer who has proposed a change to the C/C++ data type known as "timespec". You know that there…
Create a file named foo. What happens when you run the command > In foo bar if bar doesn't exist? bar exists as an ordinary file? bar exists as a directory? Make sure you precede each of your answer with the "if . . ." condition. Copy the pertaining command(s) and their output(s) from your terminal to justify your answers.
Use Linux executable objectCode6 for this question. These files are on syccuxas01.pcc.edu in directory ~michael.trigoboff/cs201/quiz02LinuxFiles. Using gdb, figure out the value that will be in ST(0) just before main returns. Question options: 1) pi - 1 2) log(base2) 10 3) log(base 10) 2
6. Given the following directory tree structure, write the full command you can use to move the "dumpling" directory into the "asian_food" directory? Hint: You can either use the full path or the relative path. If you use the relative path you should specify where in the tree you are at currently. home . miniconda3 resequencing food asian_food dumpling mexican_food
Scenario: You have been tasked with building a URL file validator for a web crawler. A web crawler is an application that fetches a web page, extracts the URLs present in that page, and then recursively fetches new pages using the extracted URLs. The end goal of a web crawler is to collect text data, images, or other resources present in order to validate resource URLs or hyperlinks on a page. URL validators can be useful to validate if the extracted URL is a valid resource to fetch. In this scenario, you will build a URL validator that checks for supported protocols and file types.
How do you avoid overwriting data when adding more data to an existing JSON file? I have an RMI code, and the program overwrites all existing values every time a client enters new data. How can I stop this? Please use JAVA code and preferrable this code should run in Intellij.

Write a script named listEmptyDir.sh that will do the following: a. Take a name of a directory as a parameter; b. Loop through all files in this directory and display their names; c. If a file is a directory and has no files in it (empty directory), add the name of this empty directory to the file EmptyDir.txt in your current directory.
