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 | }

grep

GREP(1) 						      General Commands Manual							   GREP(1)

NAME

       grep - search a file for lines containing a given pattern

SYNOPSIS

       grep [-elnsv] pattern [file] ...

OPTIONS

       -e     -e pattern is the same as pattern

       -c     Print a count of lines matched

       -i     Ignore case

       -l     Print file names, no lines

       -n     Print line numbers

       -s     Status only, no printed output

       -v     Select lines that do not match

EXAMPLES

       grep mouse file	   # Find lines in file containing mouse

       grep [0-9] file	   # Print lines containing a digit

DESCRIPTION

       Grep  searches  one  or	more  files (by default, stdin) and selects out all the lines that match the pattern.  All the regular expressions
       accepted by ed and mined are allowed.  In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or  1
       occurrences,  and  |  can  be used between two regular expressions to mean either one of them.  Parentheses can be used for grouping.  If a
       match is found, exit status 0 is returned.  If no match is found, exit status 1 is returned.  If an error is detected,  exit  status  2	is
       returned.
