<P>example, the sample license document uses the phrase
this Package to describe a software package. If you're the software developer of a new game,
Nano-Warrior, and need to save time writing copyright licenses, you can change all occurrences of
this Package to Nano-Warrior easily and quickly without using a text editor:
</P>
<!-- CODE //-->
<PRE>
# cat LICENSE | sed `s/this Package/Nano-Warrior(TM)/g'
...
1. You may make and give away verbatim copies of the source form of the
Standard Version of Nano-Warrior(TM) without restriction, provided that you
duplicate all of the original copyright notices and associated
disclaimers.
...
</PRE>
<!-- END CODE //-->
<P>The sed s, or substitute command, is used to search for all instances of the first string,
and to replace each instance with the second because of the
g, or global, command. The original text file is not changed, and you can save a new version by redirecting the output.
<P>
<P>The sed command also is designed to work using editing scripts. To make
numerous, regular changes to files, create an editing script and use your script to edit files. Use
the sed command's -f, or script file command-line option to use the script:
</P>
<!-- CODE SNIP //-->

# sed -f myscipt.sed < form.ltr >output.ltr

There are too many text filters included with your Linux distribution to
discuss in this hour; see the manual pages for the filter commands listed near
the beginning of this section. You also may want to experiment with the wc, or
word count, program, which reports the number of characters, words, and lines
in your text documents.

Applix Words

<P>There are many other Linux word processing programs besides the text editors
installed on your system. These programs may be in the public domain, distributed as
shareware, or sold commercially. One word processor, Applix Words by Applix, Inc., sold by Red
Hat Software, deserves special mention because it

<P>Applix Words requires the X Window System (see Figure 14.6). The Applixware

computer's memory to run comfortably. Once installed, run Applix Words with the following:

emacs. To start learning, select the Help menu, and then pull down the Tutorial menu item
(you also can hold down the Alt key, then press h, followed by the t key).

Spell Checking Your Documents
</A></H3>
<P>Misspelled words in your documents can be embarrassing, especially if other people
read your text. Correct spelling is an important part of writing and word processing. Just
as
</P>
<A NAME="PAGENUM-226"><P>Page 226</P></A>
<P>errors in syntax can cause programming errors, spelling errors can cause problems
in miscommunication, and loss of a potential job, customer, or the respect of a supervisor.
</P>
<P>Fortunately, your Linux distribution comes with the ispell spelling checker, so you
won't have to suffer the embarrassment of misspelling! This section shows you how to
correct documents and fix your spelling errors.
</P>
<H4><A NAME="ch14_ 13">
Correcting Documents with the ispell Command
</A></H4>
<P>The ispell command, found under the /usr/bin directory, is an interactive spelling
program you can use alone or with your text editor to correct spelling mistakes. Several
editors included with your Linux distribution, such as emacs and pico, are set up to
automatically use this program for spell checking, but using
ispell by itself is easy. For example, to check the spelling of the file
myfile.txt, use
</P>
<!-- CODE SNIP //-->
<PRE>
# ispell myfile.txt
</PRE>
<!-- END CODE SNIP //-->
<P>The ispell program loads the text, and then displays the first found error in context,
along with a single or several suggested replacements:

</PRE>
<!-- END CODE //-->
<P>Correct the spelling by either typing 0, the number of the suggested replacement word,
or R, to replace the word by retyping it. Look up other words with
L, the lookup command, which searches the system dictionary, called words, located under the
/usr/dict directory. If you use the I, or insert command, ispell creates a personal dictionary in your
home directory, using .ispell_english as a filename.
</P>
<P>You also can specify multiple documents on the ispell command line:
</P>
<!-- CODE SNIP //-->
<PRE>
# ispell *.txt
</PRE>
<!-- END CODE SNIP //-->
<P>This command line causes ispell to load each file ending in
.txt for spell checking. If you'd prefer to use ispell as the more traditional UNIX spell command, which reads a
document then prints out a list of suspected words, use
ispell's -l, or list option, on the command line:
