Sorry, there's a typo...<br />
<br />
Should be:<br />
<br />
<br />
if [ `uname -n | grep 'test'` ]<br />
&nbsp; then<br />
&nbsp; &nbsp; var=test<br />
else<br />
&nbsp; &nbsp; var=<br />
fi
</div>


Sorry, there's a typo...

Should be:


if [ `uname -n | grep 'test'` ]
  then
    var=test
else
    var=
fi

I use tcsh. Do this code apply for it?<br />
<br />
And what is fi at the end?<br />
<br />
Thanks,

Hi,<br />
I have an application running on Unix. I want to write a shell script that will detect whether I am on test machine or not.<br />
<br />
The test machine name includes the word test in it. (i.e. myapplicationtest-00-abc)<br />
<br />
The production machine does not include it. (i.e. myapplication-00-abc)<br />
<br />
So depending on the machine type, I want to assign the value test to a variable. Then I will use this variable in my following commands.<br />
<br />
Sudo code<br />

<pre><code id="code-10-27346234-1">$machineName = uname -n;
 
if ($machineName includes 'test')
{
$var=test
}
else{
$var=''
}

rsync -avz --delete /opt/mydir1/mydir2 root@myapplication$var-00-abc:/opt/mydir1/mydir2</code></pre>

How to check &quot;if matches&quot; statement for a string in shell script in UNIX?

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.

Unix OS

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.

Shell Scripting

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.
