what is the output in namechnage file and what inouts did u use? do this as if you are usingn a linux system

1. Create a script in your Labe5 folder named namechange that meets the following specifications. The script will run as: namechange -f find -r replace string-to-modify 2. Use getopts to utilize both arguments and functions. = what to replace in the filename string. Should have an argument after, save to a variable -r -f = what to find in the filename string. Should have an argument after, save to a variable -h printHelp, a function that has a help guide 3. Create a function called printHelp. printHelp should output the following: Usage: namechange -f find -r replace "string to modify" -f The text to find in the filename -r The replacement text for the new filename 4. If -r or -f have empty (no) arguments after them, output "User must provide string for find and string for replace" following by the usage guide in the printHelp function o getopts has built in ways to handle this checking 5. For the string given, string-to-modify , find the pattern to be replaced and replace it with the pattern requested using sed - you may just want to have sed use the -E option ;) # Sample runs of working script $ bash namechange -h Usage: namechange -f find -r replace "string to modify" -f The text to find in the filename -r The replacement text for the new filename $ bash namechange -f "\s" -r "-" "hello world" hello-world $ bash namechange -f "er+" -r "error" "spellingerrrr". spellingerror
