hi need help managing the alias list in a shell program ( C++ )

Shell program manages the alias list.

( | )

The first option deletes a previously defined alias. The second option defines an alias for another command.

For example, the command NEWNAME mymove deletes the alias for mymove

,the command NEWNAME mycopy cp defines mycopy as the alias for the cp command. If an alias for a command already exists, then the new alias replaces the old alias. The maximum number of aliases in the alias list should be set to 10 as the default.
