I have a requirement as mentioned below.
I have to access the last column from the table, shown below, of data (obtained from the remote node), using an Ansible playbook.

I have to use the content of the last column in a conditional statement to draw some conclusions based on it.

For example, the paths which are specified in the last but one column, corrsponding to the blade ID mentioned in column 1

  1. are in working condition if the value/content in the last (i.e.,Path state) column is either Active or Blocked
  2. are in non-working condition if the value/content in the last (i.e.,Path state) column is Inactive

I have tried a playbook like this.

---
# The objective of this playbook is to use this command "sudo dsc-show-sctp-assoc"
# and check the status of Check the status of SCTP Associations.
- name: Playbook for Checking the status of SCTP Associations
  hosts: all  
  become: true
  tasks:
  - name: Getting SCTP Association status details and saving them to a text file
    shell: dsc-show-sctp-assoc | tee sctp.txt  # "dsc-show-sctp-assoc" is used to get the tabular data from the remote node

  - name: IDNETIYING THE PASS AND FAIL CASES
    shell: cat sctp.txt | awk -F "|" {if ($NF=="Inactive") print $0, " ", '===>', "FAIL"; else print $0, " ", "====>","PASS";}'
  register: pass_fail_cases

  - name: PRINTING THE PASS AND FAIL CASES
    debug: 
      msg: "{{pass_fail_cases.stdout_lines }}"
...

The expected output is shown below

I guess that the conditional statement (if condition) of AWK command is not working as expected and hence everything is resulted as "PASS".

I tried it multiple ways. But none of them gave me the expected output.

Can someone please help to let me know where I am going wrong?

PS: I tried using AWK command here. Please suggest me the other approcahes that I can follow to get the expected output, if any

ansible awk

Following awk should work for you:

awk -F '|' '!NF {main=0} !main; /^-{3}/ {main=1; next} main {print $0, "===>", ($NF ~ /Inactive/ ? "\"FAIL\"" : "\"PASS\"")}' sctp.txt

Or to make it readable:

awk -F '|' '
!NF {main=0}
!main
/^-{3}/ {main=1; next}
main {
   print $0, "===>", ($NF ~ /Inactive/ ? "\"FAIL\"" : "\"PASS\"")
}' sctp.txt

This solutions uses a flag called main to indicate when your main body of report starts. Initially main is zero, when we encounter ----- line then we set main=1. Last block adds PASS or FAIL when main==1 depending on value of $NF.

With your shown samples only, please try following awk code.

awk '
!NF{ print; found="" }
(/^(PROGRESS|[[:space:]]+|Blade|Id|-{6}\+)|^This table was generated:/ && !found){
  if(/^-{6}\+/){ found=1 }
  print
  next
}
found{
  print $0, "===>", ($NF ~ /Inactive/ ? "\"FAIL\"":"\"PASS\"")
}
'  Input_file

OR in case you want to use it as a one-liner to use it in ansible playbook try following one-liner then:

awk '!NF{print;found=""} (/^(PROGRESS|[[:space:]]+|Blade|Id|-{6}\+)|^This table was generated:/ && !found){if(/^-{6}\+/){found=1};print;next} found{print $0, "===>", ($NF ~ /Inactive/ ? "\"FAIL\"":"\"PASS\"")}' Input_file

Explanation: Adding detailed explanation for above.

awk '                          ##Starting awk program from here.
!NF{ print; found="" }         ##If NF is NULL then print that line and Nullify found here.
(/^(PROGRESS|[[:space:]]+|Blade|Id|-{6}\+)|^This table was generated:/ && !found){  ##Checking conditions if line starts from PROGRESS OR spaces OR Blade OR Id OR 6 dashes then do following.
  if(/^-{6}\+/){ found=1 }  ##Checking if line starts from 6 dashes then set found to 1.
  print                        ##Printing line here.
  next                         ##next will skip all further statements from here.
}
found{                         ##Checking condition if found is NOT NULL.
  print $0, "===>", ($NF ~ /Inactive/ ? "\"FAIL\"":"\"PASS\"") ##Then printing current line followed by either Fail or Pass based on last field as per OP request.
}

By the way, in your code you have:

shell: cat sctp.txt | awk -F "|" {if ($NF=="Inactive") print $0, " ", '===>', "FAIL"; else print $0, " ", "====>","PASS";}'

idk why you're swapping back and forth between singe and double quotes like that but - don't. A valid syntax for what that line is trying to do would be:

shell: cat sctp.txt | awk -F "|" '{if ($NF=="Inactive") print $0, " ", "===>", "FAIL"; else print $0, " ", "====>","PASS";}'

which could be improved to (but still won't work, I'm just showing valid syntax, not correcting semantics):

shell: awk -F '|' '{print $0, " ", "===>", ($NF=="Inactive" ? "FAIL" : "PASS")}' sctp.txt

         "PASSFAIL", 5^(!_<NF), 4*!+_) "\"")' FS='[|] Inactive[ \t]*$'     \_=1 


######### # or preferably, not hard-coding in the "1" :

mawk 'BEGIN { FS = "[|][ \t]+Inactive[ \t]*$"
