------------question----------------------- a. Name your program as cmatch.c b. The objective is to locate executable programs and to display their pathname. c. A given argument will be examined along the user's path or default shell variable #PATH. To get the variable PATH, you need to use: getenv ("PATH"); d. the path is a list o directories separated by ":". To obtain a directory component, you may want to use strch to split the string. e. The suggested procedure is following: · To use chdir, opendir, and readdir in sequence, so you can examine the contents of a directory. · Examine each filename if it is matched the given command, then stop the search and print out the pathname of the command by attaching the filename to the directory name. · If no filenames are matched, then the next directory in line will be picked and redo the search. f. System calls, such as opendir (), readdir (), and getcwd (), may be needed. However, system calls such as system (), fork (), exec (), unlink () and write () are not allowed. the rest of the question is attached as zip file. the output is required and the screenshot of the output, plus the program itself. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. ## Platform it shold be able to run in unix solaris...in afs enviroment.
