Using UNIX, Part 2.
We talked about using 3 UNIX commands. In UNIX, there are many other options for using them. But for the most part, if you can use them like I have shown, you will be able to do everything you need. If you can learn these few points well, I think you will be better off than if I give you 50 options and leave you totally confused about when to do what. On some UNIX systems, an electronic version of the UNIX manual is on the system. This gives a lot more information about each command. However, it is a bit difficult to understand. If you want more information about any command, you can type man COMMAND, e.g., man ls. This will give you more ways to use the ls command. And remember, the command pwd tells what directory you are in, cd/directory changes to another directory, ls lists the contents of the directory you are in, ls more displays the directory contents 1 page at a time (the space bar gives you the next page), ls-al gives a detailed listing of the contents of the directory you are in, ls-al more displays them 1 page at a time (the space bar gives you the next page).
