The command "ip rule restore < ${path-to-ip_rules-dat}" is used to restore IP rules from a file called "ip_rules.dat" or any other file specified by the variable "path-to-ip_rules-dat".
Explanation:
- "ip rule" is a command in the Linux network configuration tool called "ip". It is used for manipulating the routing policy database and IP rules.
- "restore" is an argument of the "ip rule" command. It tells the command to restore IP rules from a file.
- "<" is a shell redirection operator that redirects the content of the file specified (in this case, "ip_rules.dat") as the input for the command.
- "${path-to-ip_rules-dat}" is a variable that holds the path to the file "ip_rules.dat". The actual path should be provided when running this command.
Overall, this command reads the content of the "ip_rules.dat" file or any specified file and uses it to restore IP rules using the "ip rule" command.
