(?=,) is a positive lookahead, which requires the following character at that point to be a comma, but doesn't capture it as part of the match. If that's too scary, you could also just put the comma back in as part of the replacement, with:<br />
<br />
Find:<br />

<pre><code id="code-20-40434500-1">(,.*?,.*?),</code></pre>
Replace:<br />

<pre><code id="code-20-40434500-2">$1unique,</code></pre>

I have this regex working within VI which replaces the 3rd occurrence of ',' with 'Unique,' 
<pre><code id="code-10-28554745-1">s/,.\{-},.\{-}\zs,/Unique,</code></pre>
<br />
I can't seem to get it to work within Sublime Text Editor. I have tried the following regex, but it doesn't replace the 3rd comma, it instead captures it and places it into my replacement string.<br />
<br />
Sample Data: echo &quot;clientRequests#300#raw,$E<wbr />POCH_TIME,<wbr />$_importEx<wbr />ternalEmai<wbr />lData,proj<wbr />_ott,ottco<wbr />re<br />
Regex Find: (,.*?,.*?,)<br />
Replace Str: $1Unique<br />
<br />
I want to find the 3rd comma so I can append to the name $_importExternalEmailData so the result is $_importExternalEmailDataU<wbr />nique. Right now it will put 'Unique' after the 3rd comma.

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.

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.

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.
