Monitor Splunk Enterprise files and directories with the CLI
On Splunk Enterprise installations, you can monitor files and directories using the command line interface (CLI). To use the CLI, navigate to the
$SPLUNK_HOME/bin/ directory from a command prompt or shell, and use the
splunk command in that directory.
The CLI has built-in help. Access the main CLI help by typing
splunk help. Individual commands have their own help pages as well. Access that help by typing
splunk help <command>.
