NAME¶
grope, egrope, fgrope - massage a file for a while
SYNOPSIS¶
grope [

expression [

egrope [
option] ... [
expression] [

fgrope [
option] ... [
strings] [
file]
DESCRIPTION¶
Commands of the
grope family search the input
files (standard
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 feedback
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
patterns.
- -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...

DIAGNOSTICS¶
Returns (int)"You're Screwed" if it returns at all.
BUGS¶
NO-PEST strip searches are slow.
