Please help with the following commands I would need to use in Linux for this assignment:

a. Use wget to retrieve the index page from www.cisco.com, Note The index files may have ^M characters run. These characters won't effect the process but can be removed with the following command: -dr' index.html >indexl.html Explain exactly what -d Ir, index.html > index.html does?(answer this questions in a txt file and add it to the zip file you turn in. b. Look over the index1 html you will see entries with that look like links, (lines such as li> lab3-2.txt is not allowed. Review the links in the file, how can you extract the web address from this file? Is there a delimiter we can use to trim down the result further? d. i. To trim down or cut text from a file we can use the cut command. The basic command such as cut -d", "-/3 would use a comma as a delimiter and return the 3rd field or token based on that delimiter. In addition, use the man pages to learn about cut ii. So the question is what delimiter would help us here? iii. Pipe the cut command to the original grep command. (save as lab3-2.tct) a.
