8.1) Finding Files

In this section you will be introduced to the Unix commands that are used to manipulate datafiles. You will learn commands called such as cat, paste, diff, grep, find, redirection and you will be introduced to linking commands together using the Unix pipe.

We will begin with finding files. These files may be lost because you are learning the Unix tree structure or because you have acquired huge numbers of data files and are looking for a file that you used some time ago or have stored away and lost.

Keep in mind in the coming pages, that if you issue a Unix command and the system doesn't respond then as a response you can hold down the 'Ctrl' button and type 'c' at the same time and this will often terminate the command and return you to the Unix system. Only use this if the Unix system is unresponsive or you need to stop a command.
