I want to print between the range two patterns if a particular pattern is present in between the two patterns. I am new to Unix. Any help would be greatly appreciated.
e.g.
Pattern1
Bombay
Calcutta
Delhi
Pattern2

Hello everyone. I'm new to the boards, I hope I can get and possibly give some help through these forums.
I need some help.
I have two CSV files, let's call them File A and File B.
This is the structure for File A:
ID, VAR1, VAR2, VAR3 - VAR50 (where the VAR 1-VAR50 are either 0 or 1)

Hi;
For sure there's an easy answer to this one that I am not finding..
I first set a variable, say
b1a:] max=5
then I want to use max to set the range for a for loop like so (it should run for i in 1:5)
b1a:] for i in {1..$max}; do echo $i; done
{1..5}
I would like the output... (2 Replies)
Dear all,
I have a file lik below: n of row=420, n of letters in each row=100000 like below: there is no space between the letters.
what I want is: the 75000th letter to the 85000th letter in each row.
how to do that? thanks a lot!

The following is part of a larger project and sed is (right now) a given. I am working on a recursive Korn shell function to "peel off" XML tags from a larger text. Just for context i will show the complete function (not working right now) here:

hi all,
Say i have a range like 0 - 1000 and i need to split into diffrent files the lines which are within a specific fixed sub-range. I can achieve this manually but is not scalable if the range increase.
E.g
cat file1.txt
Response time 2 ms
Response time 15 ms
Response time 101... (12 Replies)
Hi. I have a large data file. the first column has unique identifiers. I have approximately 5 of these files and they have varying number of columns in their rows. I need to extract ~300 of the rows in to a separate file. I'm not looking for something that would do all 5 files at once, but... (7 Replies)

In my Linux system ephemeral port range is showing different ranges as follows

cat /etc/sysctl.conf | grep net.ipv4.ip_local_port_range
net.ipv4.ip_local_port_range = 9000 65500

TPM Quote Tools

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.
