- Task1: Create a directory say, "Linux user" and it contains three files (e.g.; A, B, C). Change the directory permission first for "user", “group", “others", “all" then change the permission of files residing in the same folder/directory.arrow_forwardPlease comment all code Using a python editor, write a python script that imports os and does the following: it changes the directory to net created previously, it displays the current directory, it checks if the path to one of the subdirectories of net exists, it checks if the name of one of the files created previously is a directory, it returns the sizes of both files, uses for a loop to print the content of net as a list of strings, uses a for loop to retrieve all files with the extension .xlsx, uses a for loop to join a few files to the netarrow_forwardYou have a directory that includes the filenames Bob, Charlie, Charlene, Dick, Derby, Edward, Eddie, and Evangeline.

- Please comment all code Using a python editor, write a python script that imports os and does the following: - it changes the directory to net312 created previously.- it displays the current directory.- it checks if the path to one of the subdirectories of net312 exists.- it checks if the name of one of the files created previously is a directory.- it returns the sizes of both files.- uses for a loop to print the content of net312 as a list of strings.- uses a for loop to retrieve all files with the extension .xlsx.- uses a for loop to join a few files to the net312.arrow_forwardfind 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.arrow_forwardWrite code that when executed in PowerShell, will satisfy the following requirements: • Display the contents of the c:\windows\system32 directory. • Only display the file / directory names. • Pipe the result into the format list cmdlet • Use only one line to solve the problem.arrow_forward
