The command to edit the cron jobs for the current user is "crontab -e". This command specifically opens the current user's crontab configuration file in the default text editor set on the system. The crontab is a Unix/Linux utility that allows users to schedule tasks to run automatically at specified intervals. By using "crontab -e", users can easily add, remove, or modify scheduled tasks directly.

The other commands provided do not serve the same purpose. The "at -e" command is used for editing jobs scheduled with the 'at' command, which allows users to run tasks at a specific time but does not manage recurring tasks like cron jobs. The "atrm -e" command is intended for removing jobs scheduled with 'at', but does not allow editing of cron jobs. Finally, "systemd-edit" is not directly related to cron jobs; it is used for editing systemd unit files, which manage services in Linux systems. Thus, "crontab -e" is the correct command for editing individual user scheduled tasks in cron.
