Hello All

I have file which contain sample data like below -

test.txt

I want to write a regX which would print only those line which contain patteren like xxx or aaa bbb etc.

When ever the same character repeated atleast 3 times that line should print

Here the output should :

Any suggestion ?

g2p-sk

g2p-sk(1)							   USER COMMANDS							 g2p-sk(1)

NAME

       g2p-sk - phonetic transcription for Slovak

SYNOPSIS

       g2p-sk [--color] [--dl debug level] [--help] [--stats] [--ofile <file_name>] [<input file>]

DESCRIPTION

       The phonetic transcription is essential for some linguistic or speech recognition applications. Depending on the language either rule based
       or statistical approach is being used. g2p-sk implements the rule based approach but in the future it may be replaced by statistical one.

       Each input word consisting of the sequence of graphemes is transcribed in to the sequence of phones in the SAMPA coding. If no  input  file
       is  specified,  the  standard  input  is expected. If input file is used then the output is written in to the file as well. The filename is
       input filename with the extension "_trans.txt".

       The input output code page is ISO 8859-2. To use it with different CP use some CP converter and pipes. For example to have input and output
       in  UTF-8  use  (for interactive use): filterm UTF8-iso2 iso2-UTF8 g2p-sk or (for batch processing) iconv -f UTF-8 -t ISO_8859-2 | g2p-sk |
       iconv -f ISO_8859-2 -t UTF-8

       Performance of the phonetic transcription depend on the morphematic segmentation. To improve the quality of the morphematic segmentation is
       possible to replace the small version of the simple morphematic dictionary in the /usr/share/g2p_sk/Exceptions/morfemy.ddat with the better
       one.  The syllabic segmentation is as important as morphematic one. The syllabic segmentation is provided by sylseg-sk package.

       The design of the g2p-sk is language dependent. To use it for another language the all rules need to be rewritten.

OPTIONS

       --color
	      Enable color output.

       --dl 1..5
	      Set the debug level. Control the amount of displayed information The debug level 0 displays nothing. The maximum	level  5  displays
	      full debugging report. The default debug level is 1.

       --help Display a short help text

       --ofile <file_name>
	      Write output also in to given file.

       --stats
	      Count and display statistic for each phone

EXAMPLES

       Use standard input and debug level 3:
	      g2p-sk --dl 3

       Process all the from file aaa.txt:
	      g2p-sk aaa.txt

EXIT STATUS

       g2p-sk returns a zero if it succeeds to process all the input words
