i am running jdbc and getting following data. if I run this on SQL\> prompt

```
--backupid "2129214415_30120163393540,2129214415_30120163432904" --spoolpath /system1/1_backup

```

but on logstash output it becomes

```
command: "--backupid \"2129214415_30120163393540,2129214415_30120163432904\" --spoolpath /system1/1_backup"

```

how do I parse this and get 2129214415\_30120163393540

I try this but it does not work

```
grok {
             tag_on_failure => ["grok_parse_failed"]
             match => {"command" => "--backupid \\"%{GREEDYDATA:myid},%{GREEDYDATA:myid2}\\" }
}

```

I even try with different \ combination to esacpe that backslash and "

it works on grok debugger when I try

this works

The actual value of the command field is `--backupid "2129214415_30120163393540,2129214415_30120163432904" --spoolpath /system1/1_backup"`. There are no backslashes in it, those are just being used as escapes for the double quotes inside the string. Try

```
match => { "command" => '--backupid "%{DATA:myid1},%{DATA:myid2}"' }

```
