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!
![7 Essential JavaScript Functions]()
I remember the early days of JavaScript where you needed a simple function for just about everything because the browser vendors implemented features differently, and not just edge features, basic features, like addEventListener and attachEvent. Times have changed but there are still a few functions each developer should...
![Camera and Video Control with HTML5]()
Client-side APIs on mobile and desktop devices are quickly providing the same APIs. Of course our mobile devices got access to some of these APIs first, but those APIs are slowly making their way to the desktop. One of those APIs is the getUserMedia API...
![Create Spinning, Fading Icons with CSS3 and MooTools]()
A goal of my latest blog redesign was to practice what I preached a bit more; add a bit more subtle flair. One of the ways I accomplished that was by using CSS3 animations to change the display of my profile icons (RSS, GitHub, etc.) I...
![CSS Filters]()
CSS filter support recently landed within WebKit nightlies. CSS filters provide a method for modifying the rendering of a basic DOM element, image, or video. CSS filters allow for blurring, warping, and modifying the color intensity of elements. Let's have...
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:
