The head and tail UNIX file commands help you get to the top or bottom of a file. By default, they will show you the first or last ten lines of the file, but you can specify a different number of lines in the output, by specifying a number next to the head or tail command. The following example shows how you can get the first five lines of a file (the /etc/group file, which shows all the groups on the UNIX server): $ head -5 /etc/group root::0:root other::1:root,hpdb bin::2:root,bin sys::3:root,uucp adm::4:root $ The tail command works in the same way, but it displays the last few lines of the file. The tail command is very useful when you are performing a task like a database software installation, because you can use it to display the progress of the installation process and see what s actually happening.

To append notifications to a single shared file, the sender must obtain an exclusive read-write lock on the file before appending data to it. Before reading data, the receiver would also need to obtain an exclusive read-write lock on the file. Figure 3-5 shows the timing details.

In addition to the UNIX vi editor, there are several other alternatives you can use, including pico, sed, and Emacs. Most are simple text editors that you can use in addition to the more popular vi editor. It s worth noting that Emacs works well in graphical mode when you use the X Window System, and there are also specific editors for X, such as dtpad. For useful information on the various UNIX editors such as the Emacs, pico, and the vi editors, please go to http://www.helpdesk.umd.edu/systems/wam/general/1235/. Vim (or Vi improved) is an enhanced clone, if you will, of vi, and it is one of the most popular text editors among Linux administrators. You can download Vim from http://www.vim.org/download.php. For an excellent introduction to the Vim editor and its use with SQL*Plus, see David Kalosi s article Vimming With SQL*Plus at http:// www.oracle.com/technology/pub/articles/kalosi_vim.html.

The cat and more utilities, which you ve seen earlier in the Overview of Basic UNIX Commands section, dump the entire contents of a text file onto the screen. If you want to see only certain parts of a file, however, you can use text-extraction utilities. Let s look at how you can use some of the important text-extraction tools.

I described the grep command briefly earlier in the chapter you use the grep command to find matches for certain patterns in a string, using regular expressions. (For a good introduction to regular expressions, see the tutorial at http://www.regular-expressions.info/tutorial.html.) The word grep is an acronym for global regular expression print, and it is derived from the following vi command, which prints all lines matching the regular expression re: g/re/p

Figure 3-5. Using a single file to send notifications You can also use shared files to pass notifications even when the sender and receiver are on different machines. Some systems use a separate file server, which is usually a network addressable machine. Networked file systems make the location of the file transparent to the sender and receiver. The only requirement is that both the sender and receiver have network access to the machine. Shared files are somewhat popular in application integration frameworks, such as Sun s ToolTalk1 and IBM s WebSphere Business Integration Connect.2
