PERL FIND AND REPLACE 
In UNIX environment, the
 following combination of perl
 and find will serch for a
 particular file and replace
 the occurence of a particular
 string with another string in
 that file. This will also
 work for multiple files and
 directories.  The find
 command finds the file and
 the perl script replaces
 old string with the new one.
 
 
 At the command prompt give
 this command:
 
 # perl -pi -e  's//' `find . -name ""`
 
 NB: Perl should be in the
 path and the general regular
 expression rules apply while
 using special  characters
 for eg  / or .
