April 12, 1995 ATRUN 8

### NAME

atrun - run jobs queued for later execution

### SYNOPSIS

atrun [-l load_avg] [-d]

### DESCRIPTION

atrun runs jobs queued by at(1). Root's crontab(5) must contain the line: `

    */10     *       *       *       *       root    /usr/libexec/atrun

`

so that atrun(8) gets called every ten minutes.

At every invocation, every job in lowercase queues whose starting time has passed is started. A maximum of one batch job (denoted by uppercase queues) is started each time atrun is invoked.

### OPTIONS

-l load_avg
  Specifies a limiting load factor, over which batch jobs should not be run, instead of the compiled-in value of 1.5.

-d
  Debug; print error messages to standard error instead of using syslog(3).

### WARNINGS

For atrun to work, you have to start up a cron(8) daemon.

### FILES
