<div>
There is a few ways you can do this. Let's say the variable that contains your grepped data is called result. You can determine the length of result like this:<br />
<br />

<pre><code class="code-1 nolinks" id="code-20-36906484-1"><span>user@VMMINT01 ~/tmp $ result=&quot;this is the result&quot;</span>
<span>user@VMMINT01 ~/tmp $ echo $result</span>
<span>this is the result</span>
<span>user@VMMINT01 ~/tmp $ expr length &quot;$result&quot;</span>
<span>18</span>
<span>user@VMMINT01 ~/tmp $ echo ${#result}</span>
<span>18</span>
</code></pre>
</div>


<div>
Or assign the lengt to a variable:<br />
<br />

<pre><code class="code-1 nolinks" id="code-20-36906498-1"><span>user@VMMINT01 ~/tmp $ result_len=`expr length &quot;$result&quot;`</span>
<span>user@VMMINT01 ~/tmp $ echo $result_len</span>
<span>18</span>
</code></pre>
</div>


<div>
I tried the above suggestion, but it is printing the wrong count/length.<br />
&nbsp;There are only 3 filenames in the file but it is showing 5.<br />

</div>


<div>
Are you working in Perl or some shell scripting language like KSH, SH, CSH?<br />
<br />
For most scripting languages you could do something like:<br />
<br />
$length=`echo $var | wc -l`<br />
(count lines)<br />
<br />
$length=`echo $var | wc -c`<br />
(count characters)<br />

</div>


<div>
Hi<br />
<br />
Below is the script I am using.. I want to get the count into a variable so that I can populate that into an email subject showing the count of file names<br />
<br />
#!/bin/bash<br />
<br />
&nbsp;i=$(egrep -v &quot;^$|[/]$&quot; /usr/home/Test/Files/test_<wbr />`date +%Y%m%d`_mhl.txt);<br />
echo &quot;$i&quot;\n;<br />
$length ='echo $i|wc -l';<br />
<br />

</div>


<div>
Try it this way:<br />
&nbsp;
<pre><code class="code-1 nolinks" id="code-8224288"><span>i=$(egrep -v &quot;^$|[/]$&quot; /usr/home/Test/Files/test_`date +%Y%m%d`_mhl.txt);</span>
<span>echo &quot;$i&quot;;</span>
<span>length=$(echo $i|wc -l);</span>
<span>echo $length;</span>
</code></pre>
</div>


<div>
Above one is giving the count of file it is grepping instead of count of Filenames within the file.<br />
<br />
So right now it is grepping &quot;1&quot; file to read &nbsp;so the output is 1.
</div>

Hi,<br />
I am grepping Data from log file and assigning it to a Variable. Now I need to know length or count of that Variable. Can anyone let me know how??<br />
<br />
I mentioned Count because I am grepping the filenames into Var . For example when we print that Variable data would be:<br />
<br />
FILE1<br />
FILE2<br />
FILE3..<br />
<br />

Length of Variable in Shell

The term 'shell' refers to a general class of text-based command interpreters most often associated with the UNIX and Linux operating systems. Popular shells include Bourne, Debian Almquist (dash), Korn (ksh), Bourne Again (bash) and the C shell family (csh). Some view the DOS 'cmd' prompt as a minimal shell of sorts. It is also possible to install Cygwin on Windows and emulate a full Unix environment with complete shell capabilities. Terminal emulators, such as xterm, GNOME Terminal and OS X Terminal, can be used to access shell.
