I'm not sure why you would want to use 'grep' on a string - a string is typically a single line, and grep is used to find matches in one or more files.
If the string is very long, say 32000 characters or so, you could take the string and echo it or cat it thru grep, but again, if there is a match, the entire string would be print anyway.

Grep is a command line application that is used to search a file or files and extract data from it/them according to a pattern or filter if you prefer. Grep stands for global regular-expression.
