1. In an earlier assignment, you created a fileAsst directory containing several files. Give a command that will create a file named listing.dat, in your current (commandsAsst) directory, containing a list of the names of all the files in your fileAsst directory. The listing must not include dates, file sizes, or any information other than the names. 2. Someone has decided that the function sequentialInsert, declared in -cs252/Assignments/commandsAsst/project/arrayops.h, should be renamed orderedInsertion. Give a command to produce the altered version the header file, saving it as ~/UnixCourse/commandsAsst/arrayops.h (Something to think about: Why would the same approach not work well for changing the variable name i to i0?) 3. Sometimes programmers propose changes to an existing software definition and need to know what other code could be affected by the change. Suppose that you are a programmer who has proposed a change to the C/C++ data type known as "timespec". You know that there…

The aim of this lab is to familiarize yourself with reading and processing directories aswell as extracting file attributes using the stat() system call. You are essentially writingyour own version of the long format of the ls command. You will need to customize youroutput to match the following specifications: -o: specifies the minimum age of the files (modification timestamp) to be listed fromthe target directory. The -o argument will be followed by an integer (as a separate parameter to make things easier if you wish). This integer will represent the minimumnumber of days old the files can be in order for them to be included in your listing.As an example "-o 3" passed as arguments would mean: list all files that have beenmodified more than 3 days ago (from the current system time).
