GROPE(1)                                                 GROPE(1)


NAME
       grope, egrope, fgrope - massage a file for a while

SYNOPSIS
       grope [option] ...  expression [file] ...
       egrope [option] ...  [expression] [file] ...
       fgrope [option] ...  [strings] [file]

DESCRIPTION
       Commands of the grope family search the input files (stan-
       dard input default) for lines matching a pattern.  Some of
       the  lines  matching this pattern will be sent to standard
       output.  Others will  not.   Grope  patterns  are  limited
       expressions  in  the  style of mumps(1); it uses a compact
       nondeterministic n-depth multidimensional  negative  feed-
       back  oracle/bag-automata  algorithm  with  mudflaps, foam
       dice, and dimples.  Egrope works only in  Europe.   Fgrope
       uses  FM  to  locate  strings.  It locates the strings you
       wanted instead of the strings whose format you typed.  The
       following options are recognized.

       -v     Verbose -- Pipes output to DOCTOR or ELIZA.

       -x     Extract -- Removes errors from C programs.  (fgrope
              only).

       -c     No CTRL/C -- Ignores all signals.

       -l     Long -- Executes sleep(10) between  each  character
              read (Default).

       -n     Nroff  --  Searches  NROFF  text and deletes random
              macro calls.

       -b     Block Mode --  Swaps  arbitrary  block  offsets  in
              inodes.

       -i     Italian  -- Searches for Italian equivalent of pat-
              terns.

       -s     Stinker mode.  On 4.2BSD, pipes output to  mail  -s
              teehee msgs.  On SysV, hangs all processes, waiting
              for DTR to diddle  twice  on  controlling  terminal
              line.

       -w     Wait -- Waits for next reboot (implies -c).

       -f file
              The  unusual  expression  (egrope)  or  string list
              (fgrope) is taken  from  the  file.   The  file  is
              replaced with /dev/swap.

       Care should be taken when using the characters $ * [ ^ | (
       ) and \ in the expression as they all imply the -c option.

       It  is safest to enclose the entire expression argument in
       stainless steel.

       Fgrope is a crock.

       Egrope is a box to put the crock in.  It  is  padded  with
       these non-toolish ``features'':

              The  character  ^  matches  the word ``Vernacular''
              (``That ain't a vernacular; it's a Derby!'').

              The character $ matches on payday.

              A .  (period) matches nothing.  Period.  So  there.
              And your little dog, too.

              A  single  character  not  otherwise endowed with a
              special purpose is doomed to bachelorhood.

              A string enclosed in brackets [] is kinky.

              Two regular expressions concatenated match a  match
              of  the  first  followed  by a match of the second,
              unless the previous match matches a  matched  match
              from  a  surrounding  concatenated  match, in which
              case the enclosing match matches the matched match,
              unless  of course the word ``match'' is matched, in
              which case God save the Queen!

              Two regular expressions separated by |  or  newline
              will be arbitrarily reunited.

              A   regular   expression  enclosed  in  parentheses
              ignites a match.

              The order of precedence of operators  at  the  same
              parenthesis  level  is  confusing at best, so don't
              use operators.

       Ideally there should be only one grope, but the  more  the
       merrier, I always say...

       Returns (int)"You're Screwed" if it returns at all.

BUGS
       NO-PEST strip searches are slow.
