Ok. That's good to know. I suppose the end of line anchor ($) will work, then.

This seems to work on a tiny test file.

Code:
grep -e '^[^#]*$' testhash.txt

EDIT:

This is my file contents:
Code:
line1 has some text
line2 is a second line
li#e3 has a hash!
line4 the above line had a hash!
line# has a hash too
line6 - ^ had a hash.. bad line?
#ine7 hashline
line8 lastly the last line
#

line11 single hash and a blank line above

And this is the output:
Code:
line1 has some text
line2 is a second line
line4 the above line had a hash!
line6 - ^ had a hash.. bad line?
line8 lastly the last line

line11 single hash and a blank line above

						     TCG Software Stack Developer's Reference

NAME

       Tspi_Hash_GetHashValue - get the current hash value of a hash object

SYNOPSIS

       #include <tss/platform.h>
       #include <tss/tcpa_defines.h>
       #include <tss/tcpa_typedef.h>
       #include <tss/tcpa_struct.h>
       #include <tss/tss_typedef.h>
       #include <tss/tss_structs.h>
       #include <tss/tspi.h>

       TSS_RESULT Tspi_Hash_GetHashValue(TSS_HHASH hHash, UINT32* pulHashValueLength, BYTE** prgbHashValue);

DESCRIPTION

       Tspi_Hash_GetHashValue gets the hash value of a hash object. Tspi_Context_FreeMemory must be used to clean up after this function, as memo-
       ry is allocated for the prgbHashValue data.

PARAMETERS

   hHash
       The handle to the hash object instance whose hash value should be signed.

   pulHashValueLength
       Receives the length of the hash value data returned at the parameter prgbHashValue.

   prgbHashValue
       Receives a pointer to the hash value data.

RETURN CODES

       Tspi_Hash_GetHashValue returns TSS_SUCCESS on success, otherwise one of the following values is returned:

       TSS_E_INVALID_HANDLE
	      hHash is not a valid handle.

       TSS_E_INTERNAL_ERROR
	      An internal SW error has been detected.

       TSS_E_BAD_PARAMETER
	      One or more parameters is bad.

       TSS_E_HASH_INVALID_LENGTH
	      Hash length is inconsistent with hash algorithm.

       TSS_E_HASH_NO_DATA
	      Hash object has no internal hash value.

CONFORMING TO
