POHow to do this in PowerShell? Or : what language to use for file and string manipulation?

copied!<p>What language should I use for file and string manipulation?</p> <p>This might seem objective, but really isn't I think. There's lot to say about this. For example I can see clearly that for most usages Perl would be a more obvious candidate than Java. I need to do this quite often and at this time I use C# for it, but I would like a more scriptlike language to do this. </p> <p>I can imagine Perl would be a candidate for it, but I would like to do it in <a href="http://en.wikipedia.org/wiki/Windows_PowerShell" rel="nofollow noreferrer">PowerShell</a> since PowerShell can access the .NET library (easy). Or is Python a better candidate for it? If I have to learn a new language, Python is certainly one on my list, rather than Perl.</p> <p>What I want to do for example, is to read a file, make some changes and save it again. E.g.: open it, number all lines (say with 3 digits) and close it. Any example, in any language, would be welcome, but the shorter the better. It is utility scripting I'm after here, not OO, TDDeveloped, unit-tested stuff of course. </p> <p>What I would very much like to see is something as (<a href="http://en.wikipedia.org/wiki/Pseudocode" rel="nofollow noreferrer">pseudocode</a> here): </p> <pre><code>open foobar.as f foreach line in f.lines line.addBefore(currenIteratorCounter.format('ddd') + '. ') close f </code></pre> <p>So: </p> <pre><code>bar.txt Frank Zappa Cowboy Henk Tom Waits numberLines bar.txt bar.txt 001. Frank Zappa 002. Cowboy Henk 003. Tom Waits </code></pre> <p>UPDATE: </p> <p>The Perl and Python examples here are great, and definitely in the line of what I was hoping and expecting. But aren't there any PowerShell guys out there?</p>
