This command, atrm ${10}, is used to remove a scheduled job from the "at" queue in a Unix-like system.

Here's a breakdown of the command:

• atrm: This is the command itself, used to remove scheduled jobs from the "at" queue.
• ${10}: This is a parameter or argument to the atrm command. The use of ${10} implies that the value passed as the 10th argument to the script or command will be used here.

In Unix-like systems, the at command is used to schedule one-time commands or scripts to be executed at a specific time in the future. When a job is scheduled using at, it gets added to a queue managed by the system. The atrm command allows the removal of jobs from this queue before they are executed.

In this specific case, the command is trying to remove the scheduled job corresponding to the 10th argument passed to the script or command where this line of code is located. The value of ${10} will be substituted with the actual 10th argument when the command is executed.

For example, if you run a script with the command ./myscript.sh arg1 arg2 arg3 ... arg10, where arg10 is the value you want to remove from the "at" queue, then the command atrm ${10} will remove the corresponding job.
