|
||
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.
|
||
|
||
<h3>How to use</h3>
|
||
Sample execution of wc:
|
||
|
||
<pre>
|
||
wc file1.txt file2.txt
|
||
</pre>
|
||
|
||
will output:
|
||
|
||
<pre>
|
||
40 149 947 file1.txt
|
||
2294 16638 97724 file2.txt
|
||
2334 16787 98671 total
|
||
</pre>
|
||
|
||
The first column is the count of newlines, meaning that the text file
|
||
<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.<br>
|
||
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 in all.<br>
|
||
|
||
