Hi
I am trouble parsing through a file with spaces in the filename. I need to grab "supportIDPS/SCM/windows_install/file groups/dds.fgl" and then do a md5sum on it. I am using sh.
Any help is appreciated.
Here is an example of the input file:

Hi,
I grep for a pattern in a list of files.
"grep -i -l $pattern *.datx*"
it may give me n number of files.
say for eg, it gives me 2 files.

I am using the following code to read filename from the directory:
for i in ` ls $inputDir | grep $partialName*.csv`
do
echo $i

But the echo is giving me the following:

Any ideas anyone? I... (2 Replies)

Hi,
I am searching for a file named "Backup.txt" but I don't know in which directory it is.
Can someone tell me, how I can search recursiv in all directories and subdirectories?

I need to construct a command that finds directories which contains more than n matches of a certain filename.
E.g. I have many directories at different locations and want to find all directories that has 2 or more .dat-files.
I thought of using find and maybe the exec parameter to issue an... (5 Replies)

I want to read in a file, and plot the data in matlab. However, I do not like hardwiring filenames into my codes, so I always give the user the option to specify what the filename is. I am pretty inexperienced with matlab, so I have no... (0 Replies)
Hi Guys,
I have the following input.
test_junk_file__20120210092009.txt
latest_file__20120210092009.txt
side_load_junk_file__20120210092009.txt
I need to exclude the timestamp part from the file.
so, the output should be as follows.

DESCRIPTION
TPM Quote Tools is a collection of programs that provide support for TPM based attestation using the TPM quote operation.
A TPM contains a set of Platform Configuration Registers (PCRs). In a well configured machine, some of these registers are set to known
values during the boot up process or at other times. For example, a PCR might contain the hash of a boot loader in memory before it is
run.
The TPM quote operation is used to authoritatively verify the contents of a TPM's Platform Configuration Registers (PCRs). During provi-
sioning, a composite hash of a selected set of PCRs is computed. The TPM quote operation produces a composite hash that can be compared
with the one computed while provisioning.
To use the TPM quote operation, keys must be generated. During provisioning, an Attestation Identity Key (AIK) is generated for each TPM,
and the public part of the key is made available to entities that validate quotes.
The TPM quote operation returns signed data and a signature. The data that is signed contains the PCRs selected for the operation, the
composite hash for the selected PCRs, and a nonce provided as input, and used to prevent replay attacks. At provisioning time, the data
that is signed is stored, not just the composite hash. The signature is discarded.
An entity that wishes to evaluate a machine generates a nonce, and sends it along with the set of PCR used to generate the composite PCR
hash at provisioning time. For this use of the TPM quote operation, the signed data is ignored, and the signature returned is used to val-
idate the state of the TPM's PCRs. Given the signature, the evaluating entity replaces the nonce in the signed data generated at provi-
sioning time, and checks to see if the signature is valid for the data. If so, this check ensures the selected PCRs contain values that
match the ones measured during provisioning.
A typical scenario for an enterprise using these tools follows. The tools expect AIKs to be referenced via one enterprise-wide Universally
Unique Identifier (UUID). The program tpm_mkuuid creates one.
For each machine being checked, an AIK is created using tpm_mkaik. The key blob produced is bound to the UUID on its machine using
tpm_loadkey. The public key associated with the AIK is sent to the entities that verify quotes. Finally, the expected PCR composite hash
is obtained using tpm_getpcrhash. When the expected PCR values change, a new hash can be generated with tpm_updatepcrhash.
The program to obtain a quote, and thus measure the current state of the PCRs is tpm_getquote. The program that verifies the quote
describes the same PCR composite hash as was measured initially is tpm_verifyquote.
