Remove some text with shell scripts?

I wanted to get some help on how I can use cygwin, which has bash to shell script the following:

I have a txt file that contains the following:

action "action1"

  reset

  type xformbin

  http-method-limited POST

  http-method-limited2 POST

exit



action "action2"

  reset

  admin-state disabled

  type results

  http-method-limited POST

  http-method-limited2 POST

exit



action "action3"

  reset

  admin-state disabled

  type setvar

  http-method-limited POST

  http-method-limited2 POST

exit

I was hoping a shell script could be written to remove the block where admin-state = disabled?

So, I'm hoping I can iterate through the txt file and if admin-state = disabled, remove everything between "action" and "exit" from that particular block.

I would expect the following final results from the sample text:

action "action1"

  reset

  type xformbin

  http-method-limited POST

  http-method-limited2 POST

exit

Thank you.

sed '/disabled/,/exit/ d' infile? Maybe write the output to another location until you're confident it's doing what you want. I'm leery of jumping straight to -i.

So you want the whole block ignored if it has 'disabled' in the middle, but printed if it does not.

sed -n '

  /action/,/exit/ {

  /action/ { x; d; }

  H;

  /exit/ { x;

    /disabled/ d;

    p;         d;

  }

}' x

This will do nothing unless in a block from action to exit. In those -

If a line has action, store it and delete the pattern space to trigger the next read.

Otherwise append the line to the stored hold space.

If the line had exit,

swap the hold space into the pattern space

if the collected pattern has disabled, delete it to trigger reading the next record;

if not, print it, then delete it to trigger reading the next record.

The output:

$: sed -n '

  /action/,/exit/ {

    /action/ { x; d; }

    H;

    /exit/ { x;

      /disabled/ d;

      p;         d;

    }

  }' infile

action "action2"

reset

admin-state enabled

type xform

http-method GET

http-method-limited POST

http-method-limited2 POST exit

Hope that helps.
