Best Alternative to Search Text strings in directory
Hi All,

We have a file "Customers.lst". It contains list of all the Customers.

There is directory which has number of text files and each file containing name of defaulter customers.

We want to search for all the customers available in "Customers.lst" file against the list of files containing the name of default customers and then
print the Default customer name and the file in which it is available.

Currently we are reading Customers.lst file line by line and then doing grep in the directory.
Code:
for customername in `cat ${customerlistfile}`
do
   cd $dir
   echo "Searching for $customername in the $dir" >> $mainlog
   find . -name "*"|xargs grep -il $customername |sed 's/.*/'"${customername}"', &/' >> $mainout
done

Is there a better way to do this operation or any suggestions on the above command to make it faster.

REgards,
Arun M

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

SEE ALSO

       lcp_crtpol2(8), lcp_crtpolelt(8), lcp_crtpollist(8), openssl(1).
