Reformat ini string

I have a text file which contain one line.

2019-06-19 09:00 Login successfully [ Section 1] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 2] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 3] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 4] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 5] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 6] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN Program Terminated...

I have tried awk but it prints only the last section:

awk '{for(i=1;i<=NF;i++) {if ($i == "Section") beginning=i; if($i== "OPEN") ending=i }; for (j=beginning;j<=ending;j++) printf $j" ";printf "\n"   }'

Section 6] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN

How do I reformat to this pattern?

This command works in a more general case (for example, if don't have Param1, Param2 but actual identifiers) and matches your expected output more precisely:

sed 's/ \(Login successfully\|Program Terminated...\)//g; s/\[ /[/g; s/\(\[\|[Ss]tate\)/\n\1/g; s/\([A-Z][A-Za-z0-9]* :\)/\n\1/g'

How it works:

The command has 4 separate expressions separated by ;:

  1. s/ \(Login successfully\|Program Terminated...\)//g - removes unneeded Login successfully and Program Terminated... with a space before them
  2. s/\[ /[/g - removes space after [
  3. s/\(\[\|[Ss]tate\)/\n\1/g - adds a newline before State or state
  4. s/\([A-Z][A-Za-z0-9]* :\)/\n\1/g - adds a newline before "Params", where its name consists of uppercase letter ([A-Z]) and then any ASCII letter or digit ([A-Za-z0-9])

Example:

$ STRING="2019-06-19 09:00 Login successfully [ Section 1] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 2] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 3] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 4] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 5] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 6] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN Program Terminated..."
$ echo $STRING | sed 's/ \(Login successfully\|Program Terminated...\)//g; s/\[ /[/g; s/\(\[\|[Ss]tate\)/\n\1/g; s/\([A-Z][A-Za-z0-9]* :\)/\n\1/g'

Replace [<space> with [ and add a newline before [, Param and State strings:

$ sed 's/\[ /[/g; s/\(\[\|Param\|State\)/\n\1/g' <<<'2019-06-19 09:00 Login successfully [ Section 1] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 2] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 3] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 4] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 5] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN [ Section 6] Param1 : xxxx Param2 : xxxx Param3 : xxxx Param4 : xxxx State: OPEN Program Terminated...'
