Splunk TA for bash_history. For some background, see Duane's Blog Post.

Sourcetypes: bash_history

Inputs:  YES
Index-time config: YES	
Search-time config: YES	

In addition to the Splunk setup requirements, you will also need to:

• (as root) mkdir -m 1777 /var/log/bashhist
• Put contents of etc/profile.d into your real /etc/profile.d so it runs for everyone

Or do whatever you have to do on your OS. MacOS for example does not by default call /etc/profile.d scripts. You're kinda on your own, or submit a PR :)
