Greetings & Happy New Years To All!
A client of mine FTP'ed their files up to the server and it all ended up being in UPPERCASE when it all should be in lowercase. Is there a builtin command or a script anyone knows of that will automagically convert all files to lowercase?
Please advise asap... (4 Replies)
It will only accept one argument where it should be upper or lowercase. if user choose to convert filnames to upper case than it should convert to upper or vice versa. if no action taken by the user then should not do anything
any of the files in the current directory. (5 Replies)
Hey, I've just started learning shell script today.
How would I write a bash script file that changes file names from uppercase to lowercase in that directory, the program should warn the user and NOT overwrite the existing file if it's already in lowercase?
for example in a directory i... (1 Reply)
Inside a script I have 2 variables COMP=cy and PT=t. further down the same script I require at the same line to call those 2 variables the first time uppercase and after lowercase ${COMP}${PT}ACE,${COMP}${PT}ace. Can somebody help me
Thanks in advance

hi,
i need to write a bash script that does two things.
the program will take from the command line a file name, which is a C code, and an integer, which is the size of my indentation
i would then have to indent every nested code by the number of columns provided by the user in the... (1 Reply)
I just started to learn unix...
and i needed to make a basic script.
i need to
1. read a file (.txt)
2. count the words of EVERY sentece
3. sentences with odd number of words need to be converted into lowercase
sentences with even number of words need to be converted into uppercase

1) Write a shell script to convert an input file to all upper case. Name your shell script toupper.sh.
Hint: tr ' ' ' ' will convert all lower case letters to upper case
To use your script, try the following command:

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.
