    GREP(I)                      5/15/74                      GREP(I)

    NAME
         grep - search a file for a pattern

    SYNOPSIS
         grep [ -v ] [ -b ] [ -c ] [ -n ] expression [ file ] ...

    DESCRIPTION
         Grep  searches  the input files (standard input default) for
         lines matching the regular expression.  Normally, each  line
         found  is  copied to the standard output.  If the -v flag is
         used, all lines but those matching are printed.  If  the  -c
         flag is used, only a count of matching lines is printed.  If
         the -n flag is used, each line is preceded its relative line
         number  in  the  file.  If the -b flag is used, each line is
         preceded by the block number on which it was found.  This is
         sometimes  useful in locating disk block numbers by context.

         In all cases the file name is shown if there  is  more  than
         one input file.

         For a complete description of the regular expression, see ed
         (I).  Care should be taken when using the characters $ * [ ^
         | ( ) and \ in the regular expression as they are also mean-
         ingful to the Shell.  It is generally necessary  to  enclose
         the entire expression argument in quotes.

         cated.
