From the man page for GNU find:

Quote:

-print0
True; print the full file name on the standard output, followed by a null character (instead of the newline character that `-print' uses). This allows file names that contain newlines or other types of white space to be correctly interpreted by programs that process the find output. This option corresponds to the `-0' option of xargs.

From the man page for GNU xargs:

Quote:

--null, -0
Input items are terminated by a null character instead of by whitespace, and the quotes and backslash are not special (every character is taken literally). Disables the end of file string, which is treated like any other argument. Useful when input items might contain white space, quote marks, or backslashes. The GNU find -print0 option produces input suitable for this mode.

Combining the two:

Code:

find . -type f | xargs chksum

Or, much much simpler, and works across all platforms:

Code:

find . -type f -exec chksum {} \;

cksum

cksum(1)						      General Commands Manual							  cksum(1)

NAME

       cksum - print file checksum and sizes

SYNOPSIS

       [file ...]

DESCRIPTION

       The command calculates and prints to standard output a checksum for each named file, the number of octets in the file and the filename.

       uses  a	portable  algorithm  based on a 32-bit Cyclic Redundancy Check.  This algorithm finds a broader spectrum of errors than the 16-bit
       algorithms used by (see sum(1)).  The CRC is the sum of the following expressions, where x is each byte of the file.

	      + x^8 + x^7 + x^5 + x^4 + x^2 + x^1 + x^0 x26 + x23 + x22 + x16 + x12 + x11 + x10 + x7 + x5 + x4 + x2 + x1 + x0

       The results of the calculation are truncated to a 32-bit value.	The number of bytes in the file is also printed.

       Standard input is used if no file names are given.

       is typically used to verify data integrity when copying files between systems.

EXTERNAL INFLUENCES

   Environment Variables
       determines the locale to use for the locale categories when both and the corresponding environment variable (beginning with do not  specify
       a locale.  If is not set or is set to the empty string, a default of "C" (see lang(5)) is used.

       determines  the	locale	for  interpretation of sequences of bytes of text data as characters (e.g., single- verses multibyte characters in
       arguments and input files).

       determines the language in which messages are displayed.

       If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are  set  to	"C".   See
       environ(5).

RETURN VALUE

       Upon completion, returns one of the following values:

	      All files were processed successfully.

	      One or more files could not be read or another error occurred.

       If an inaccessible file is encountered, continues processing any remaining files, but the final exit status is affected.
