Recursive grep
This tip is for grepping a pattern even in the sub-directories of a particular directory in addition to the files in the current directory.
Since grep -R <> <> is not available on all flavors, this can be really helpful.
The command is as follows :-
find <path> -name <filenamepattern> | xargs grep <searchstring>
The arguments are self-explanatory.
The output of find will be xarg'ed to the input of grep
and these will be searched for searchstring.
