Searching for multiple patterns in files
I have a situation where I need to search for multiple strings (error messages) such as 'aborted' 'file not found' etc in directory having logs. I have put all the error messages in a text file and using the command.
Code:
grep -f <textfile> <filetobegrepped>

I'm doing this thru a script where I have a loop which will get the file name to be grepped and search for the messages. If ound I need to display the file which contains the pattern.
During exeuction I have the error as follows:
Code:
Usage: grep -hblcnsviw pattern file

Can somebody help what could be wrong here..

This is the piece of code
Code:
for FILE in *; do
   if [ -d $FILE ]
   then
      echo "This is a directory. Search not required"
   else
      grep -f messages.txt $FILE
      if [ $? = 0 ]
      then
         echo "Please check $FILE for errors" >> errorrep
      fi
   fi
done

err_print_errors_fp

ERR_print_errors(3)						      OpenSSL						       ERR_print_errors(3)

NAME

       ERR_print_errors, ERR_print_errors_fp - print error messages

SYNOPSIS

	#include <openssl/err.h>

	void ERR_print_errors(BIO *bp);
	void ERR_print_errors_fp(FILE *fp);

DESCRIPTION

       ERR_print_errors() is a convenience function that prints the error strings for all errors that OpenSSL has recorded to bp, thus emptying
       the error queue.

       ERR_print_errors_fp() is the same, except that the output goes to a FILE.

       The error strings will have the following format:

	[pid]:error:[error code]:[library name]:[function name]:[reason string]:[file name]:[line]:[optional text message]

       error code is an 8 digit hexadecimal number. library name, function name and reason string are ASCII text, as is optional text message if
       one was set for the respective error code.

       If there is no text string registered for the given error code, the error string will contain the numeric code.

RETURN VALUES

       ERR_print_errors() and ERR_print_errors_fp() return no values.

SEE ALSO

       err(3), ERR_error_string(3), ERR_get_error(3), ERR_load_crypto_strings(3), SSL_load_error_strings(3)

HISTORY

       ERR_print_errors() and ERR_print_errors_fp() are available in all versions of SSLeay and OpenSSL.
