Recursive Find from Command Line
Probably a dozen times a day I need to search any given project for specific code keywords. Most of the time it's within a specific project but then there are times where I don't remember which directory or project the specific text is -- from my blog to my many Mozilla projects, I have code all over my local machine and it's oftentimes difficult to find something I need.
Most of the time I need to open my text editor and have it do the hard work of what I'm looking for but that's probably not efficient -- a more efficient tool would come from command line and thanks to CommandLineFu.com, I found the perfect command:
# Search all ".js" files for "debounce"
# Spits out file path, line number, and snippet where string appears
find . -name "*.js" -exec grep -in -H "debounce" {} \;
The command above searches files recursively to find the desired string, outputting the source file and the text which the string occurs in!
![9 Mind-Blowing WebGL Demos]()
As much as developers now loathe Flash, we're still playing a bit of catch up to natively duplicate the animation capabilities that Adobe's old technology provided us. Of course we have canvas, an awesome technology, one which I highlighted 9 mind-blowing demos. Another technology available...
![Create a Sheen Logo Effect with CSS]()
I was inspired when I first saw Addy Osmani's original ShineTime blog post. The hover sheen effect is simple but awesome. When I started my blog redesign, I really wanted to use a sheen effect with my logo. Using two HTML elements and...
![Drag and Drop MooTools File Uploads]()
Honesty hour confession: file uploading within the web browser sucks. It just does. Like the ugly SELECT element, the file input is almost unstylable and looks different on different platforms. Add to those criticism the fact that we're all used to drag and drop operations...
![HTML5 Input Types Alternative]()
As you may know, HTML5 has introduced several new input types: number, date, color, range, etc. The question is: should you
start using these controls or not? As much as I want to say "Yes", I think they are not yet ready for any real life...
Recently I’m using:
I think grep also has an option to filter on file extension too and I use it sometimes, but I don’t know it by heart.
The output on this looks pretty must the same as with the functionality already built into grep using the
-rand--includeflags. I also tend to add the-nflag to output the line numbers as well. I believe this should line be equivalent.https://vivekragunathan.wordpress.com/more-resources/cmd-line-sucks/

grepThe find trick was one I learned at university in the 1990s, when most greps didn’t have the recursive flag. My vague recollection is that GNU grep introducing -r gave much of the competition a bit of a kick up the arse, and now it’s fairly common, but the find trick is still useful on older or more obscure Unix platforms…
Pretty sure you have a typo in there. “*.[js]” means “*.j” or “*.s”, which is likely to find nothing.
Good point — left some testing in there. Updated!

Oh, you were filtering for JavaScript files only. That’s as easy as
:-)
Wasn’t able to execute this through the command line:
