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


     grep - search a file for a pattern


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


     Grep will search the input files  (standard  input  default)

     for  each line containing the regular expression.  Normally,

     each line found is printed on the standard output.   If  the

     -v  flag  is used, all lines but those matching are printed.

     If the -c flag is used, each line printed is preceded by its

     line number If the -n flag is used, each line is preceded by

     the name of the input file and its relative line  number  in

     that 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.  If

     interrupt is hit, the file and line number last searched  is


     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

     meaningful  to  the  Shell.   It  is  generally necessary to

     enclose the entire expression argument in quotes.
