Re: Excluding files with grep

[DarkRick]

Hello,

First, thanks for the answers, these were really useful. Second, I think
that it doesn't work in a windows system with Unix Utils because the Unix
Utils are limited, and doesn't have some parameters, then, when I try to use
the sentence "grep -rHc '[[:print:]]' mydirecotry | grep ':0$'" it shows no
answer.

So, and i try to call "grep -rHc '[[:print:]]' mydirecotry" and it shows
this answer:
Error: Invalid option -H

And when I use "grep ':0$' ." it shows this answer:
File .\filename.ext:
Error: Line too long (file may be binary) - search aborted

So, and when I display the Unix Utils Grep Help. it shows:
Turbo GREP  Version 1.2  Copyright (c) 1987, 1989 Borland International
Syntax:  GREP [-rlcnvidzuwo] searchstring file[s]

Options are one or more option characters preceeded by "-", and optionally
followed by "+" (turn option on), or "-" (turn it off).  The default is "+".
   -r+  Regular expression search       -l-  File names only
   -c-  match Count only                -n-  Line numbers
   -v-  Non-matching lines only         -i-  Ignore case
   -d-  Search subdirectories           -z-  Verbose
   -u-  Update default options          -w-  Word search
   -o-  UNIX output format                   Default set: [0-9A-Z_]

A regular expression is one or more occurrences of:  One or more characters
optionally enclosed in quotes.  The following symbols are treated specially:
   ^  start of line             $  end of line
   .  any character             \  quote next character
   *  match zero or more        +  match one or more

   [aeiou0-9]   match a, e, i, o, u, and 0 thru 9
   [^aeiou0-9]  match anything but a, e, i, o, u, and 0 thru 9

Thank you a lot again...
