try on your machine

The given command performs logging by sending a message to the system logger with a specified priority level.

Here is a breakdown of the command:

echo ${log_entry}: This part echoes the value stored in the variable log_entry. ${log_entry} is a placeholder which represents the actual value of the variable.
|: This is a pipe symbol that is used to redirect the output of the previous command as input to the next command.
logger: This command is used to send messages to the system logger.
--priority ${user-warning}: This specifies the priority level at which the log message should be recorded. ${user-warning} represents the value of a variable called user-warning, which would be holding a priority level, such as warning.

In summary, the command takes the value stored in the log_entry variable, pipes it to the logger command, and records it in the system log with the priority level specified by the user-warning variable.
