Question

i need help with this scripting assignment in power shell thanks

Lab 7: PowerShell Search and Report Search Report host path date Execution time nnn Directories n, nnn, nnn Files nnnnnnn Sym links nnnnnnn Old files nnnnnnn Large files nnnn, nnn Graphics files nnnnnnn Executable files nnnnnnn Temporary files n, nnn, nnn TotalFileSize nnnn, nnn Introduction Lab 7 is nearly identical to Lab 2, except it is written in PowerShell, uses no UNIX/Linux tools to do its work, creates no temporary files and has redefined an "executable file". Just as in Lab 2, you will search a folder and produce a summary report. Your srpt script should exit with return code 0 (zero) after producing its report unless the path was not specified on the commandline. If your script is executed without a PATH, issue this usage statement and exit with return code 1: The specific requirements for how to obtain the list of file system objects and the definition of an executable file have changed in this assignment. Note the specific requirements below. Usage: srpt.ps1 PATH Requirements Additional Requirements Your script shall be named srpt.ps1, be located in the root of your repo and be marked executable. Here is how you execute your script: ./srpt.ps1 PATH Example ./srpt.ps1 /var/classes/c53030/1ab7/testfiles Your script shall inspect the file names of every file and directory in the folder represented by PATH and accumulate a count of each of the following file system objects: . You may call get-childitem once and only once to retrieve an array of all file system objects in the requested PATH. Save the results to an array variable and iterate across them with foreach. You may not call any external Linux programs except date and hostname. • You may not create any temporary files (it should not be necessary) • Do not "prompt" the user to enter any information. Use only the folder specified on the commandline. • Use self-documenting variables to hold the counts. • Format counts with commas for readability. HINT: SintVariable.ToString("NO") will format the contents of $intVariable with commas and no decimal places for printing as a string) • Hint: use getdate to obtain a date object, then .addDays(-365) to calculate the date 365 days in the past. • Output the date in the report header as produced by the Linux date utility. Use the program hostname to obtain and print the hostname in the report header. For example, here is how to obtain the current date from the date program and store it into variable $todaysDate: • Every file • Every subdirectory (excluding "PATH" itself) • Every symbolic link • Every file that is 365 days old or older (old files) • Every file that is larger than 500,000 bytes (large files) • Every graphics file (any file with suffix of .jpg, gif or .bmp) • Every executable file (any file with a suffix of bat, .ps1 or .exe) • Every temporary file (any file with a suffix of ".0") • Total byte count of each file $todaysDate = & date • Execution time is calculated from invocation and ends just before printing the summary report. • Use whitespace and indenting to make your script readable. • Add comments to your script to document your logic. Your srpt script shall produce a report in this format in this order (note the exact spelling of the labels, the spacing and the commas in the numbers): Clone your private repo on github.com
