Hi, I need help.
I have to write this homework...

"Write program xgrep, which will print files containing/not containing given string. Rules for file search should be same as for command find. Program should search both text and binary files."

can you help me please?

Something tells me you haven't really had a crack at this yourself.

People around here don't tend to be keen to do other peoples' homework, it's only fair to tell you, but if you have a shot and have specific questions, then fine.

You haven't really given enough information to take this any further. For one thing, I strongly suspect you've posted it in the wrong place; the way to do this using a shell script would arguably be a near-one-liner calling grep - an existing program which'll be installed nearly everywhere a shell is installed, and which does what the specification asks for and then some.
