write those scripts in linux $4)$ Delete all duplicate files

Write a shell script to deleteDuplicate that deletes all files $($Keep one and remove the other$)$ that are a copy of a

given file. The command deletes replication f$1$ f$2...$ fn should remove all the files f$2$ through fn that are exact

copies of f$1.$ Exact means that the file name and size are the same.

Sample:

$($Assume that the midterm file in directory dir$1$ has another copy inside directory dir$2)$

$./$deleteDuplication dir$1$ dir$2$

File midterm has been deleted from the dir$2$ directory.

$...$

If there aren$$t two arguments or dir$1$ and dir$2$ are not a directory, the script should print an appropriate error message

to stderr and exit.

$3.$ Report:

$5)$ Count and display all files that contain the exact word:

Write a countWord script that accepts as many arguments as possible $($up to $8)$: the word to search for and a list

of directories. The script should display all files with their directories.

Your script should print an error if:

$$ The first argument is not a type of regular file

$$ The number of arguments is less than two.

Sample:

$./$countWord Computer Comp$311$ Comp$433$ Comp$438$

The Word $$Computer$$ appears $4$ times in the following Files with the

corresponding lines

$/$Comp$311/$midterm$.$doc line $10$

$/$Comp$311/$resume$.$txt line $5$

$/$Comp$433/$technology$.$txt$.$ line $3$

$/$Comp$438/$Myfiles$.$html line $25$

$6)$ Count the number of files that have the same name inside different directories.

Write a countFiles script that accepts two directories as arguments: the script should display all files with the

same name.

Your script should print an error if:

$$ the first argument is not a type of directories

$$ the number of arguments is not equal to two.

Sample:

$./$countFiles Comp$311$ Comp$2311$

The following files appear in the directories $$Comp$311$ and $$Comp$2311$
