that use the files, not by the Unix filesystem itself. Unix programs do abide by one convention, however. Text files use a single newline character (linefeed) between lines of text, rather than the carriage return-linefeed combination used in Microsoft Windows or the carriage returns used in the Macintosh. This difference may cause problems when you bring files from other operating systems over to Unix. Windows files will often be littered with carriage returns (Ctrl-M), which are necessary for

JP [4] It's usually also a good idea to be sure that the input and outputs are redirected (Section 43.1, Section 36.16) away from the terminal, maybe to the system console instead. On systems and shells that kill background jobs when you log out, use nohup (Section 23.10). Killing All Your Processes On many Unix systems, kill (Section 24.12) interprets the special "process ID" -1 as a command to signal all your processes (all processes with your user ID), except for the process sending the

your first shell starts. (The system program that starts your shell, like login(1), could do the job, I guess.) Login Shells, Interactive Shells Each Unix shell (sh, csh, etc.) can be in interactive mode or noninteractive mode. A shell also can act as a login shell or a nonlogin shell. A shell is a shell is a shell — e.g., a login bash shell is the same program (like /bin/bash) as a nonlogin bash shell. The difference is in the way that the shell acts: which setup files it reads, whether it

you might need the details from Section 38.5, too. After you've made an archive, you'll probably want to restore it, at least as a test to be sure your archive is okay. Section 38.6 explains how. If there isn't a tape drive on your computer, read Section 38.7 about using a drive on another computer. tar copies a directory tree, recursively, from top to bottom. What if you don't want to archive everything? You can back up just some files by combining ls -lt and find. Some versions of tar have
