Getting 15 characters after search phrase
I have data that looks like this:

Code:
2002  140  40800.0060  GPS 20  C1  25477810.2305
2002  140  41100.0060  GPS 20  C1  25298056.0453

I need to get data after certain pattern.. for example if i search for C1
it should return

Code:
25477810.2305
25298056.0453

To achieve this, it should:

1) In the best scenario, if possible, it would start after the space/spaces that come after the search word, print the characters, and stop when space is found again

2) if that is not possible, other way would be to return 15 characters after the search pattern(after = the pattern itself would be excluded).

I tried with grep and sed, but could not get the results i wanted..

Thank you in advance!

rngtest

RNGTEST(1)						      General Commands Manual							RNGTEST(1)

NAME

       rngtest - Check the randomness of data using FIPS 140-2 tests

SYNOPSIS

       rngtest [-c n | --blockcount=n] [-b n | --blockstats=n] [-t n | --timedstats=n] [-p | --pipe] [-?] [--help] [-V] [--version]

DESCRIPTION

       rngtest works on blocks of 20000 bits at a time, using the FIPS 140-2 (errata of 2001-10-10) tests to verify the randomness of the block of
       data.

       It takes input from stdin, and outputs statistics to stderr, optionally echoing blocks that passed the FIPS tests to stdout (when operating
       in pipe mode).  Errors are sent to stderr.

       At  startup,  rngtest will throw away the first 32 bits of data when operating in pipe mode.  It will use the next 32 bits of data to boot-
       strap the FIPS tests (even when not operating in pipe mode).  These bits are not tested for randomness.

       Statistics are dumped to stderr when the program exits.

OPTIONS

       -p, --pipe
	      Enable pipe mode.  All data blocks that pass the FIPS tests are echoed to stdout, and rngtest operates in silent mode.

       -c n, --blockcount=n (default: 0)
	      Exit after processing n input blocks, if n is not zero.

       -b n, --blockstats=n (default: 0)
	      Dump statistics every n blocks, if n is not zero.

       -t n, --timedstats=n (default: 0)
	      Dump statistics every n secods, if n is not zero.

       -?, --help
	      Give a short summary of all program options.

       -V, --version
	      Print program version

STATISTICS

       rngtest will dump statistics to stderr when it exits, and when told to by blockstats or timedstats.

       FIPS 140-2 successes and FIPS 140-2 failures counts the number of 20000-bit blocks either accepted or rejected by  the  FIPS  140-2  tests.
       The  other  statistics  show  a	breakdown of the FIPS 140-2 failures by FIPS 140-2 test.  See the FIPS 140-2 document for more information
       (note that these tests are defined on FIPS 140-1 and FIPS  140-2  errata  of  2001-10-10.  They	were  removed  in  FIPS  140-2	errata	of
       2002-12-03).

       The speed statistics are taken for every 20000-bit block trasferred or processed.

EXIT STATUS

       0 if no errors happen, and no blocks fail the FIPS tests.

       1 if no errors happen, but at least one block fails the FIPS tests.

       10 if there are problems with the parameters.

       11 if an input/output error happens.

       12 if an operating system or resource starvation error happens.
