How do I remove control characters from a shell script command-line argument<br />
<br />
A shell script is automatically invoked with a total of 9 command-line arguments. One argument is being received with an angled bracket embedded in the text - example follows:<br />
<br />
Firewall PIX port 3 denied access &gt;&nbsp;MAC unknown<br />
<br />
Angled bracket is being processed as a redirect character and a file named &quot;MAC unknown&quot; is created<br />
<br />
So, how do I remove angled bracket from command-line argument???<br />

Shell scripting

A scripting language is a programming language that supports scripts, programs written for a special run-time environment that automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripting languages are often interpreted (rather than compiled). Primitives are usually the elementary tasks or API calls, and the language allows them to be combined into more complex programs. Environments that can be automated through scripting include software applications, web pages within a web browser, the shells of operating systems (OS), embedded systems, as well as numerous games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language.

Scripting Languages

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.
