How to use Linux swatch commands

Swatch can be used to monitor system records and perform specified actions when a specific event is detected. The events monitored by swatch and the actions of the corresponding events are stored in the swatch configuration file. The default configuration file is. swatchrc under the root directory. However, in Red Hat Linux, the default root directory does not exist. in the swatchrc configuration file, you can set/usr/doc/swatch-2.2/config_files/swatchrc. copy the personal file to. swatchrc, and then modify. the event to be monitored and the action to be executed by swatchrc.

Syntax
