/W:30-Defines the number of seconds to wait between retries.Īs you can see, the number of retries is very large (one million), which is not practical in most cases./R:1000000-Defines the number of retries on failed copies, for example, if a file is locked.The extra T stands for 'timestamps ' DA is the same as for directories. /COPY:DAT-Defines what to copy for files.D stands for 'data' and A stands for 'attributes.' /DCOPY:DA-Defines what to copy for directories.In this case, the command copies all filenames with all extensions. The first asterisk (*) represents the filename part, and the second asterisk represents the extension. The $i expands/reads the variable, replacing it with the current number being handled.Let's take a closer look at what the options mean: This iterates through every number in the sequence 1000–1100 and assigns the current number to the variable named i, a common shorthand for 'index'. What you want is a for loop, as suggested in your other post: If you wanted to copy directories, you add the -r option to the command. For completeness, the errors you got were because, being a potentially expensive operation, cp doesn't copy directories by default. So what it tried to do was copy the file filename and directories 1, 2, 3, and 4 into directory 5 (which isn't what you wanted to do). When executed, the program cp attempts to copy all the arguments, except the last one, into the final argument. When you say mkdir, the shell expands that into cp filename 1 2 3 4 5. It may be worthwhile to find a beginner shell tutorial online to familiarize yourself with the basic utilities and syntax.
