Every now and then it would be nice to have a print statement for javascript. Alert is ok, but if you want the contents of an array, it can be time consuming.
function debugln($line) {
// make a div with id="debug_area"
var debugit = document.getElementById("debug_area");
debugit.appendChild(document.createTextNode($line));
debugit.appendChild(document.createElement("br"));
}
function myonload() {
this.debugln("test message");
this.debugln("this message is on another line");
}

Find is a great utility which we use all the time, here is how to find a file
find . -name "file.c" -print
suppose you want to zip up a set of files
find directory_a directory_b file_a -print | zip -@
if there is a directory with thousands of entries, find will blow out, and you need to use xargs:
find . -name "*.cpp" -print | xargs grep -e "some text"
If you have subversion, and you do a search files, and not the .svn files, use:
find . -name .svn -prune -o -type f -print | xargs grep -e "some text"
