                               GREP.EFI (UEFIX64)
                                 RELEASE NOTES
                           version_number=4.01.1.0001

OVERVIEW

  grepx64.efi is an UEFI shell application that allows user to search for a string or 
  a series of strings from a file and write the value to a new file and set them to 
  environment variables.

  Use "..." for more than one string to search, for example: "system part number".

  If the strings being searched are found, environment variables: GREPVALUE1, GREPVALUE2 
  & etc will be generated to keep the value. The value is the number of characters found 
  after the searched string where the length is being defined by the user through the 
  <value length> argument.Use wildcard '*' as value length to get the entire line where 
  it will stop when \n or EOF found.
  
  Environment variable: GREPCOUNT will also be generated to keep the numbers of found.

  -line is an optional flag to grep the value from the start of the line where the patterns found. 

USAGE

    Syntax:  grepx64.efi <file to search> <strings to search> <file to write> <value length> [-line]
