Splunk Search

How to compare multiple files by diff command in search?

I have a question about diff command in search.

Of course though, a diff command compares two files,
I want to compare multiple files.
For example, when three configuration files (a.conf, b.conf, c.conf) were put into an indexer,
I want to compare those files at one search like below.

  1. Compare a.conf with b.conf
  2. Compare a.conf with c.conf
  3. Displays the each differences

Can we loop the command by reading the list file?
Any idea anyone?

Thank you.

The presentation is not the best, but this does what you want:

index=_internal | head 3 | appendpipe [diff pos1=1 pos2=2 | eval diff = _raw]  | appendpipe [diff pos1=1 pos2=3 | eval diff= _raw] | stats values(diff)

From the class

s=a OR s=b |stats count values(source) BY _raw, lineNum |search (count=1 source!=a) OR (count=2 source!=a)
