- In a short bash script named listdirs.sh that lists the names of the directories (the names only not the files contained in the directory) that are within the the directory provided as the single argument. The directory names are printed one per line. It prints the directories only, not symbolic links to directories. Please do this with a for-loop that for each entry to the directory provided as argument checks if it is a directory and if it is prints its name. If you run your script on red you should get red 302 % ./listdirs.sh / boot dev eecs etc home jas local media mnt obj opt pkgcache proc root run srv sys tmp usr var xconf xsys red 303 % To submit your script enclose it in a tar file using the command tar cf listdirs.tar listdirs.sh) Write Linux commands for the following:i) Copy a file test1.py from Prac01 directory to Subdir1 directory in the followingdirectory structure.FOPPrac01Prac02Prac03-Subdir1Subdir2(Where FOP is at the top level then Prac01, 02 and 03 are at next level and Subdir1and 2 are next to next level.)ii) To delete a directory DIR which has a file test2.py in it.You work for a small company that keeps the following information about its clients:• first name• last name• a 5-digit user code assigned by your company.The information is stored in a file clients.txt with the information for each client on one line(last name first), with commas between the parts.

- On a notepad of Microsoft Windows, what are the commands in creating a batch file that will create a directory named Chanel in drive C: then copy all files in drive C: that ends in .bat to the directory Chanel and display all files copied.In Fedora 37: 1. Create a directory named Module8 and navigate to that directory. 2. Create a file named pay.dat in Module8 with the following contents (in bold) for Employee ID, Employee Name, and Pay Rate (per hour); remember to press enter after each line: 0001:John Smith:15.40 0002:Jane Smith:15.41 0003:George Jungle:12.10 0004:Ursula Jungle:16.11 3. Use the cut command and cut the 2nd and 3rd field. 4. Reopen pay.dat and add the entry for Jane Smith at the end. So, now there will be 5 lines and the result should look like this: 0001:John Smith:15.40 0002:Jane Smith:15.41 0003:George Jungle:12.10 0004:Ursula Jungle:16.11 0002:Jane Smith:15.41 5. Run the uniq command to display duplicates that are in the file. 6. Sort the data in pay.dat by the rate of pay. 7. Sort the data in reverse order by the employee's ID. 8. Take screen captures and put them in a single MS Word document.In UNIX Say there is a file, students, under your home directory. Here is the content of the file students: 1001, Joe Smith, 111 Main Street 1002, Mary Johnson, 287 Broadway Ave 1003, Taylor Farlan, 255 Becker Street Use cut command to show only the third column of the file (only write down the command)
- in fedora 37 1. Create a directory named Module9 and navigate to that directory. 2. Copy the file pay.dat from Module8 to Module9. Here it is again, just in case: 0001:John Smith:15.40 0002:Jane Smith:15.41 0003:George Jungle:12.10 0004:Ursula Jungle:16.11 3. Using a pipe symbol for filtering and sort the data to stdout. Enter: cat pay.dat | sort 4. Now, on your own, using a pipe symbol for filtering and sort the data in descending order to stdout and append that to a file named SortPay.dat. 5. Copy pay.dat to three files named: pay10,dat, pay12.dat, and pay02.txt. You may need to use multiple commands. 6. Use pattern matching to locate only pay02.txt. 7. Enter the command to remove pay2.dat and redirect both stdin and stdout to a file named RemovePay.txt. 8. Run the command in step 7 again. 9. Display the contents of RemovePay.txt 10.
