Delete first line from file and more....
Hello, I have to deal with several files that will be named something like this:
E00001.TXT, E00002.TXT etc.
Each file will have a alpha character on the first position of the first line which I want to place in a variable, then delete the entire line leaving the remainder of text. This new file I want to be named the original filename prefixed by the character I previously extracted so the new file might be RE00001.TXT. Usually, out of habit I call tcl scripts to do file manipulation but I wanted to know if there was a fairly starighforward way to do this all in my Unix script (ksh). I don't know much about sed or awk so if you give examples with that and don't mind providing a brief description of what does what that would be helpful. Could the grep command provide all the functionality I'm asking for?
TIA

lcp_crtpollist
LCP_CRTPOLLIST(8) User Manuals LCP_CRTPOLLIST(8)
NAME
lcp_crtpollist - create an Intel(R) TXT policy list
SYNOPSIS
lcp_crtpollist COMMAND [OPTION]
DESCRIPTION
lcp_crtpollist is used to create an Intel(R) TXT policy list.
OPTIONS
--create
Create an TXT policy list. The following options are available:
--out file policy list file
[--ver version] version
[file]... policy element files
--sigh Sign an TXT policy list.
--pub key-file PEM file of public key
--out file policy list file
[--priv key-file] PEM file of private key
[--rev rev-ctr] revocation counter value
[--nosig] don't add SigBlock
--addsig
--sig file file containing signature (big-endian)
--out file policy list file
--show file
policy list file
--help Print out the help message.
--verbose
Enable verbose output; can be specified with any command.
EXAMPLES
Create policy list:
Assuming there have been two element file mle.elt and pconf.elt generated by lcp_crtpolelt(8) The following example can create an unsigned
policy list:
lcp_crtpollist --create --out list-unsig.lst mle.elt pconf.elt
Sign policy list:
Unsigned policy list can be signed by the command lcp_crtpollist(8) or openssl(1). The openssl(1) signing is supported for cases where the
signing environment is separate from the policy creation environment and the software allowed to run there is strictly controlled and
already supports openssl(1).
The following example uses openssl(1) to sign the list:
1 openssl rsa -pubout -in privkey.pem -out pubkey.pem
2 cp list-unsig.lst list-sig.lst
3 lcp_crtpollist --sigh --pub pubkey.pem --nosig --out list-sig.lst
4 openssl genrsa -out privkey.pem 2048
5 openssl dgst -sha1 -sign privkey.pem -out list.sig list-sig.lst
6 lcp_crtpollist --addsig --sig list.sig --out list-sig.lst
lcp_crtpollist can also be used to sigh a policy list. The following example are intended to be mutually exclusive with the preceding exam-
ple.
1 openssl genrsa -out privkey.pem 2048
2 openssl rsa -pubout -in privkey.pem -out pubkey.pem
3 cp list-unsig.lst list-sig.lst
4 lcp_crtpollist --sign --pub pubkey.pem --priv privkey.pem --out list-sig.lst
