This app provides a custom splunk command "base10convert" which converts decimal(i.e. base 10) number to any base.
Pass any decimal field(e.g. jobid) and desired base(e.g. 8) to base10convert command and it will return a new field(e.g. jobid_base_8).
Syntax:
...| base10convert jobid 8|table jobid jobid_base_8
...| base10convert jobid 36|table jobid jobid_base_36
