NAME

     grep - search a file for a pattern



SYNOPSIS

     grep [ -v ] [ -l ] [ -n ] expression [input] [output]



DESCRIPTION

     Grep will search the input file (standard input default) for

     each line containing the regular expression.  Normally, each

     line found is printed on the output  file  (standard  output

     default).   If  the  -v  flag  is  used, all lines but those

     matching are printed.  If the -l flag  is  used,  each  line

     printed  is  preceded by its line number.  If the -n flag is

     used, no lines are printed, but the  number  of  lines  that

     would  normally have been printed is reported.  If interrupt

     is hit, the number of lines searched is printed.



     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.  (Precede them by \)

     truncated.
