[sed] Finding and sticking the pattern to the beginning of successive lines up to the next pattern
I have a file like below.

Code:
2018.07.01, Sunday
09:27 some text 123456789 0 21 0.06 0.07 0.00
2018.07.02, Monday
09:31 some text 123456789 1 41 0.26 0.32 0.00
09:39 some text 456789012 1 0.07 0.09 0.09
09:45 some text 932469494 1 55 0.29 0.36 0.00
16:49 some text 123456789 0 48 0.12 0.15 0.00
20:13 some text 123456789 0 46 0.12 0.15 0.00

I want the sed command to find the pattern YYYY.MM.DD, Day of week (Y-year, M-month, D-Day, e.g. 2018.07.01, Sunday) and:

  1. to copy the pattern to the buffer
  2. to remove the pattern from the given line and then
  3. to past the pattern into the line below so that you get the effect below


Code:
2018.07.01, Sunday 9:27 am some text 123456789 0 21 0.06 0.07 0.00
2018.07.02, Monday 9:31 some text 123456789 1 41 0.26 0.32 0.00
2018.07.02, Monday 09:39 some text 456789012 1 0.07 0.09 0.09
2018.07.02, Monday 9:45 some text 932469494 1 55 0,29 0,36 0,00
2018.07.02, Monday 16:49 some text 123456789 0 48 0.12 0.15 0.00
2018.07.02, Monday 20:13 some text 123456789 0 46 0.12 0.15 0.00

I will be grateful for constructive answers.

pkeyparam

PKEYPARAM(1SSL) 						      OpenSSL							   PKEYPARAM(1SSL)

NAME

       openssl-pkeyparam, pkeyparam - public key algorithm parameter processing tool

SYNOPSIS

       openssl pkeyparam [-help] [-in filename] [-out filename] [-text] [-noout] [-engine id] [-check]

DESCRIPTION

       The pkeyparam command processes public key algorithm parameters.  They can be checked for correctness and their components printed out.

OPTIONS

       -help
	   Print out a usage message.

       -in filename
	   This specifies the input filename to read parameters from or standard input if this option is not specified.

       -out filename
	   This specifies the output filename to write parameters to or standard output if this option is not specified.

       -text
	   Prints out the parameters in plain text in addition to the encoded version.

       -noout
	   Do not output the encoded version of the parameters.

       -engine id
	   Specifying an engine (by its unique id string) will cause pkeyparam to attempt to obtain a functional reference to the specified
	   engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms.

       -check
	   This option checks the correctness of parameters.

EXAMPLE

       Print out text version of parameters:

	openssl pkeyparam -in param.pem -text

NOTES

       There are no -inform or -outform options for this command because only PEM format is supported because the key type is determined by the
       PEM headers.
