Remove some text with shell scripts?
0
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.
