//Global means that an entire file is searched.  
//Regular Expression means that a regular expression string is used to establish a search pattern.  
//Print means that the command will display its findings.  
//Simply put, grep searches an entire file for the pattern you want and displays its findings.  
//  
//The use syntax is different from the traditional Unix syntax, I prefer a syntax similar to  
//csc, the C\# compiler.

// grep \[/h|/H\] - Usage Help  
//  
// grep \[/c\] \[/i\] \[/l\] \[/n\] \[/r\] /E:reg\_exp /F:files

// /c - print a count of matching lines for each input file;  
// /i - ignore case in pattern;  
// /l - print just files (scanning will stop on first match);  
// /n - prefix each line of output with line number;  
// /r - recursive search in subdirectories;  
//  
// /E:reg\_exp - the Regular Expression used as search pattern. The Regular Expression can be delimited by  
// quotes like "..." and '...' if you want to include in it leading or trailing blanks;  
//  
// /F:files - the list of input files. The files can be separated by commas as in /F:file1,file2,file3  
//and wildcards can be used for their specification as in /F:\*file?.txt;
