# Linux swatch Command [ Linux Command Manual](#) The Linux swatch command is used for system monitoring. swatch can be used to monitor system log files and execute specified actions when specific events are found. The events monitored by swatch and the corresponding actions are stored in swatch's configuration file. The default configuration file is `.swatchrc` in the user's home directory. However, in Red Hat Linux, there is no `.swatchrc` configuration file in the default user home directory. You can copy the `/usr/doc/swatch-2.2/config_files/swatchrc.personal` file to the user's home directory as `.swatchrc`, and then modify `.swatchrc` to specify the events to monitor and the actions to execute. ### Syntax swatch [-r ] **Parameter Description**: * -A The delimiter for actions in the configuration file, default is comma. * -c Specify the configuration file instead of using the default configuration file. * -f Check the specified log file, and will not continue monitoring that log file after checking. * -I Specify the delimiter for input records, default is newline character. * -P Specify the delimiter for events in the configuration file, default is comma. * -r Restart at the specified time. * -t Check the specified log file, and will monitor subsequent records added to the log file. ### Example Start system monitoring # swatch [ Linux Command Manual](#)
