Create a Linux shell script that will search for US phone numbers in files that are in a directory that has been passed in as a parameter to your script. The script must recognize phone numbers in the following formats: (570)555-1212, 570.555.1212, 570-555-1212, and +1.570.555.1212. Your script should also attempt to minimize false positives. The script should work on files that are compressed or uncompressed.

Create a bash script that will take two directories as input parameters, iterate over the lists of files, and report files which are either present in one directory but missing in the other, or present in both directories but differ in content. The script MUST NOT consider subdirectories or files therein. The script should work with both relative and absolute paths. This also means the output format displayed must contain a relative or absolute path depending on what the original argument was (see attached image for commands allowed)

Windows 10 File Explorer is moving a file from C:data to E:data. The two file systems are NTFS on C: and FAT32 on D:.What happens to file permissions when D:/ Drive files are copied?

You shall implement a Microshell, “MSH”.  MSH shall provide the following functions: Provide a shell-like interface for launching new programs: When MSH starts running, it will print a prompt "cssc0000% " (replace cssc0000 with your username) and then wait for the user to type in a file name. Note, MSH will NOT have any shell built-in functions (such as cd, setenv, printenv, bg, fg, etc), with the exception of #5 (below). When the user enters a filename and hits the “enter” key, MSH then reads the filename entered and determines if the file is an executable file. If it isn't, MSH will print a useful error message to the user and then return to #1 above (display a new prompt and wait for user input). If it is an executable file, then MSH will create a new process and run this program in the new process. Note – you will need to determine whether the filename is a fully qualified path name or if the file needs to be searched for (fully qualified pathnames begin with a slash (i.e. "/"),…

find The find command takes a pattern as a command-line argument and recur- sively searches through directories to find a filename matching that pattern. It should print a relative path starting with "./" for every file/directory that matches. For example, running ./find 1s.c from within the hw2 directory should print ./1s.c. If run from the parent directory, the output would be . /hw2/1s.c. There may be multiple matches. If we run ./find .c from within the hw2 directory, we should see: ./find.c ./1s.c ./tree.c The output does not need to be sorted. If nothing matches, it shouldn't print anything. Pattern matching should be case sensitive.

Write a shell script that contains a hashpling and comments. It should perform thefollowing tasks:a. Displays a list of currently logged-in usersb. Displays the system’s host namec. Displays the time and dated. Displays the disk usagee. Displays the current working directoryf. Displays the pathname to the BASH shell
