my_grep

This is a very useful little UNIX tool, I wrote for win32, very very long time ago, the code may be dreadful but it'll be ok, grep is a matching tool that permit to filter many things very quickly, like a listing for example, if you have a list of 10000 element but you only want to see the one which contains truc, it's easy with grep, you just grep with "truc" as argument and it's done

my_grep allow 4 arguments

-h   will print the filename of the matching file

-n   will print the number of the line read in the input stream

-i   will make my_grep to be case-insensitive

-v   will match everything that doesn't match with the pattern you give (reverse mode)

For more details about it, type "man grep" in google
