<p>The program reads either standard input or a list of files and
|
|||
|
|
generates one or more of the following statistics: newline count,
|
|||
|
|
word count, and byte count. If a list of files is provided, both
|
|||
|
|
individual file and total statistics follow.</p>

|
|||
|
|
<p>Sample execution of wc:</p>
|
|||
|
|
<pre> wc file1.txt file2.txt</pre>
|
|||
|
|
<p>will output:</p>
|
|||
|
|
<pre>
|
|||
|
|
40 149 947 file1.txt<br>
|
|||
|
|
2294 16638 97724 file2.txt<br>
|
|||
|
|
2334 16787 98671 total</pre>
|
|||
|
|
|
|||
|
|

|
|||
|
|
<code>file1.txt</code> has 40 newlines while bar has 2294 newlines-
|
|||
|
|
resulting in a total
|
|||
|
|
of 2334 newlines. The second column indicates the number of words in each
|
|||
|
|
text file showing that there are 149 words in <code>file1.txt</code>
|
|||
|
|
and 16638 words in
|
|||
|
|
<code>file2.txt</code> – giving a total of 16787 words. The last
|
|||
|
|
column indicates the
|
|||
|
|
number of characters in each text file, meaning that the file
|
|||
|
|
<code>file1.txt</code> has
|
|||
|
|
947 characters while bar has 97724 characters – 98671 characters all
