Shell script to copy particular file from directories recursively

I have directory path in which there are several sub directories. In all these sub dir there will be one env.cnf file. I want to copy this env.cnf file from
each sub dir's and place them in destination path by creating same filename as sub dir_env.cnf.

After copying env.cnf files from source to destination dir, I have to run few unix commands(grep) on each files and print the grep command o/p in result files in output dir.

I have seen that we can use the below command to do the recursive file copy part but don't know how to process grep command on each files

Code:
 
find /src_path/to/ -iname '*.cnf' -exec cp {} /new/directory/ \;

Ex:
path : /tmp/config/ has 3 sub dir's
Code:
SubA ---- has env.cnf
SubB ---- has env.cnf
SubC ---- has env.cnf
.
.
.

after running the script, it should place the env.cnf file in input dir in /tmp/Config/input as name:
Code:
SubA_env.cnf
SubB_env.cnf
SubC_env.cnf
.
.
.

now run the same script again on each files present in the input dir to perform grep command and put the output in output dir in /tmp/Config/output/
Code:
SubA_env.txt
SubB_env.txt
SubC_env.txt

ManyThanks,

SPKAC(1)							      OpenSSL								  SPKAC(1)

NAME
spkac - SPKAC printing and generating utility SYNOPSIS
openssl spkac [-in filename] [-out filename] [-key keyfile] [-passin arg] [-challenge string] [-pubkey] [-spkac spkacname] [-spksect section] [-noout] [-verify] [-engine id] DESCRIPTION
The spkac command processes Netscape signed public key and challenge (SPKAC) files. It can print out their contents, verify the signature and produce its own SPKACs from a supplied private key. COMMAND OPTIONS
-in filename This specifies the input filename to read from or standard input if this option is not specified. Ignored if the -key option is used. -out filename specifies the output filename to write to or standard output by default. -key keyfile create an SPKAC file using the private key in keyfile. The -in, -noout, -spksect and -verify options are ignored if present. -passin password the input file password source. For more information about the format of arg see the PASS PHRASE ARGUMENTS section in openssl(1). -challenge string specifies the challenge string if an SPKAC is being created. -spkac spkacname allows an alternative name form the variable containing the SPKAC. The default is "SPKAC". This option affects both generated and input SPKAC files. -spksect section allows an alternative name form the section containing the SPKAC. The default is the default section. -noout don't output the text version of the SPKAC (not used if an SPKAC is being created). -pubkey output the public key of an SPKAC (not used if an SPKAC is being created). -verify verifies the digital signature on the supplied SPKAC. -engine id specifying an engine (by its unique id string) will cause spkac to attempt to obtain a functional reference to the specified engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms. EXAMPLES
Print out the contents of an SPKAC: openssl spkac -in spkac.cnf Verify the signature of an SPKAC: openssl spkac -in spkac.cnf -noout -verify Create an SPKAC using the challenge string "hello": openssl spkac -key key.pem -challenge hello -out spkac.cnf Example of an SPKAC, (long lines split up for clarity): SPKAC=MIG5MGUwXDANBgkqhkiG9w0BAQEFAANLADBIAkEA1cCoq2Wa3Ixs47uI7F PVwHVIPDx5yso105Y6zpozam135a8R0CpoRvkkigIyXfcCjiVi5oWk+6FfPaD03u PFoQIDAQABFgVoZWxsbzANBgkqhkiG9w0BAQQFAANBAFpQtY/FojdwkJh1bEIYuc 2EeM2KHTWPEepWYeawvHD0gQ3DngSC75YCWnnDdq+NQ3F+X4deMx9AaEglZtULwV 4= NOTES
A created SPKAC with suitable DN components appended can be fed into the ca utility. SPKACs are typically generated by Netscape when a form is submitted containing the KEYGEN tag as part of the certificate enrollment process. The challenge string permits a primitive form of proof of possession of private key. By checking the SPKAC signature and a random challenge string some guarantee is given that the user knows the private key corresponding to the public key being certified. This is important in some applications. Without this it is possible for a previous SPKAC to be used in a "replay attack". SEE ALSO
