I don't think you can have a swiss army knife solution to a wild card problem. Please decently describe the data conents / structure in all cases, for every case, in detail. Are above the only three cases, or are there more? Is that pipe symbol enclosed in spaces or not always? Could it be used as a field separator? WIll the more-than-four-line data always be using braces to enclose the last field? One level of braces only?

You seem to want to print sth. like

Code:

server1 drwxr-xr-x
server2 drwxr-xr-x

in the "good cases". What should be the output in the "FAILED" cases? What in the multiline case?

You could use sth. like this to get the full records to operate upon:

Code:

awk -F\| '
function RDREST()       {getline X; $0 = $0 " | " X
                        }
/{$/    {while (! /}/) RDREST()
        }
NF < 4  {RDREST()
        }
1
' file
server1 | CHANGED | rc=0 >> | drwxr-xr-x. 8 root root 77 Apr 18  2018 /directory1
server2 | CHANGED | rc=0 >> | drwxr-xr-x. 7 root root 120 Feb 14  2019 /directory2
server3 | FAILED | rc=2 >> | ls: /director3: No such file or directorynon-zero return code
server5 | FAILED | rc=2 >> | ls: cannot access /sirectory3: No such file or directorynon-zero return code
server4 | UNREACHABLE! => { |     "changed": false, |     "msg": "Data could not be sent to remote host \"server4\". Make sure this host can be reached over ssh: ", |     "unreachable": true | }

say I'm doing awk 'NR==534' Is there a way to display 534 535 536 537? without appending to a variable? per line? maybe an easier way with a different command? My first impression was NR==534-537 but that would be too easy :P

case(n) 						       Tcl Built-In Commands							   case(n)

__________________________________________________________________________________________________________________________________________________

NAME

       case - Evaluate one of several scripts, depending on a given value

SYNOPSIS

       case string ?in? patList body ?patList body ...?

       case string ?in? {patList body ?patList body ...?}
_________________________________________________________________

DESCRIPTION

       Note:  the  case  command  is  obsolete	and  is  supported only for backward compatibility.  At some point in the future it may be removed
       entirely.  You should use the switch command instead.

       The case command matches string against each of the patList arguments in order.	Each patList argument is a list of one or  more  patterns.
       If  any	of  these patterns matches string then case evaluates the following body argument by passing it recursively to the Tcl interpreter
       and returns the result of that evaluation.  Each patList argument consists of a single pattern or list of patterns.  Each pattern may  con-
       tain  any of the wild-cards described under string match.  If a patList argument is default, the corresponding body will be evaluated if no
       patList matches string.	If no patList argument matches string and no default is given, then the case command returns an empty string.

       Two syntaxes are provided for the patList and body arguments.  The first uses a separate argument for each of the  patterns  and  commands;
       this  form  is convenient if substitutions are desired on some of the patterns or commands.  The second form places all of the patterns and
       commands together into a single argument; the argument must have proper list structure, with the elements of the list  being  the  patterns
       and commands.  The second form makes it easy to construct multi-line case commands, since the braces around the whole list make it unneces-
       sary to include a backslash at the end of each line.  Since the patList arguments are in braces in the second form, no command or  variable
       substitutions are performed on them;  this makes the behavior of the second form different than the first form in some cases.
