Can I issue a "_bump" from the command line?

[Lowell]

I'd like to script a _bump call after replacing the favicon.ico. (This is something I do after each splunk install or upgrade.) Is there an quick way to do this?

Preferably, is there are way to do this without requiring splunkweb to be running?

For anyone following along at home. Here's a shell script I wrote to do increment the version number from the command line.

Here's the contents of do_bump.sh:

#!/bin/bash
# Default splunk home if not already set
SPLUNK_HOME=${SPLUNK_HOME-/opt/splunk}

bump=`cat $SPLUNK_HOME/var/run/splunk/push-version.txt`
echo "Current version: $bump"
let bump++
echo -n $bump > $SPLUNK_HOME/var/run/splunk/push-version.txt
echo "New version:  $bump    (Restart splunkweb?)"

Since I ended up here, x-posting -- if anyone wants to do this with Javascript, it's far easier and doesn't require a splunkweb restart:

This value is read directly from a text file. If you read the file, increment the value, write it back, then start/restart splunkweb you will get the desired effect.

You may not need to do this as the install/upgrade should already be breaking the users cache as each version is included in the cache breaking mechanism.

It looks like push-version.txt is the file you are talking about. I've added an answer with a simple script to do increment this value. Thanks for leading me in the right direction. (BTW, I think I often forget to replace the "favicon.ico" until after I've started splunk after an upgrade, so I'll add this logic to my "post-install" script and that should make sure the right icon gets seen by the users.)
