C language

tucp The second utility you will build is called tucp, a variant of the UNIX tool cp. In this project, this command is used to copy files or a group of files. It creates an exact image (copy) of a file found on a disk. The tucp command requires at least two filenames in its arguments. The following are the possible command usages: tucp Sourcefile Destinationfile tucp Sourcefile Directory tucp Sourcefile-1 Sourcefile-2 Sourcefile-3 Sourcefile-n Directory

Details If the tucp command contains two file names, then it copies the contents of the 1st file to the 2nd file. If the 2nd file doesnt exist, then it first creates a file with the specified name and the content of the first file is copied to it. But if the second file already exists, then it is simply overwritten without any warning. If the tucp command has one or more arguments specifying source file names and following those arguments, an argument specifying a directory name, then the command copies each source file to the destination directory with the same source file name. The destination file is created if did not exist, or overwritten if it already existed. The Linux function stat() can be used to determine information about a file. The stat struct returned by the function includes a field, st_mode , that can be used to determine if the path evaluated by stat() is a file or a directory. Use man to learn about the functions stat() and inode().
