what about awk?

my_command | awk '{ print $2 }'

<div>
But if you prefer &quot;sed&quot;:<br />
<br />
my_command | sed -n 's@^/dev/sdf *@@p'
</div>


But if you prefer "sed":

my_command | sed -n 's@^/dev/sdf *@@p'

<div>
Thank you! saved me so many hours :)

<div>
in perl, it would be:<br />

<pre><code id="code-20-41023279-1">my_command | perl -ne 'if (m{^/dev/sdf\s+(\S+)}) { print $1 }'</code></pre>
</div>


in perl, it would be:


my_command | perl -ne 'if (m{^/dev/sdf\s+(\S+)}) { print $1 }'

<div>
<div class="content wysiwyg-content">
I would like to extract the volume id which is associated with the location /dev/sdf<br />
<br />
My script outputs the following:<br />
<br />
/dev/sdf &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; vol-606f548d<br />
/dev/sdb &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;vol-5e6c89b2<br />
/dev/sda1 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vol-046c89e8<br />
<br />
I would like to pipe it to sed or perl to extract this ouput:<br />
<br />
vol-606f548d<br />
<br />
I got as far as this:<br />
<br />
my_command | sed -n '/sdf/p'<br />
<br />
but this gives me the whole line:<br />
/dev/sdf &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vol-606f548d<br />
<br />
Thanks,<br />

Perl is a high-level, general-purpose, interpreted, dynamic programming languages with over 25 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large-scale development projects.  Perl gained widespread popularity as a Common Gateway Interface (CGI) scripting language, in part due to its regular expression and string parsing abilities. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications.

Perl

Development in most programming languages is done with an editor or integrated development environment (IDE). Dev Tools covers issues with the use of that software, rather than the actual programming being written. XCode, Visual Studio and Eclipse are some of the more popular development tools.
