What's the full list of command line needed by app scripts (in /opt/splunk/etc/apps/Splunk_TA_nix/bin)? We have to deploy the app in server with minimal OS packages installation.
To some extent the list of required command line applications depends on what you enable in the *NIX app. For example, if your environment does not provide "top" then you don't have to enable the top-calling scripted input.
For a list of available scripted inputs you can take a look inside the app. The scripts are located in ...unix.tar.gz/unix-4.6-133346.spl/unix/bin/, usually the name of the script is synonymous with the command line application called. When in doubt, take a look inside the scripts.
