A couple simple command lines I particularly like

$ find ./src -name '*.java' -exec grep -Hn Foo {} \;

- print the file name, line number, and line from any file with 
extension .java in the subdir src which contains the string Foo.

$ find ./src -name '*.java' -exec sed -e "s/Foo/Bar/g" -i.bak {} \;

- replace all occurances of Foo with Bar in any file with extension 
.java in the subdir src; make a backup of the original file with 
extension .bak if changes are made.
