appropriate privileges is able to display information about all jobs.
-f job-file Read in the commands contained in job-file instead of using standard input.
-l [job-id ...] List the jobs specified. If no job-id s are given, all jobs are listed.
-m Send mail to the invoking user after the job has run, announcing its comple-
tion. Unless redirected elsewhere within the job, standard output and stan-
dard error produced by the job are automatically mailed to the user as well.
-q queue Submit the specified job to the queue indicated (see queuedefs (4)). Queues
a,
b, and d through y can be used.
at uses queue a by default. batch always
uses queue
b. All queues except b
require a time or a -t specification.
at -qb is equivalent to batch. When used with the
-l option, limit the
search to that particular queue.
-r job-id ... Remove the jobs specified by each job-id .
-t spectime Define the absolute time to start the job.
spectime A date and time in the format:
[[CC]YY]MMDDhhmm[.ss]
where the decimal digit pairs are as follows:
CC The first two digits of the year (
19, 20).
YY The second two digits of the year (69−99, 00−68
). See
WARNINGS.
MM The month of the year (
01−12).
DD The day of the month (01−31).
hh The hour of the day (00−23).
mm The minute of the hour (00−59).
ss The second of the minute (00−61).
If both CC and YY are omitted, the default is the current year.
If CC is omitted and YY is in the range
69−99, CC defaults to
19.
Otherwise,
CC defaults to 20.
The range for ss provides for two leap seconds. If ss is
60 or 61,
and the resulting time, as affected by the TZ environment variable,
does not refer to a leap second, the time is set to the whole minute
following mm.
If ss is omitted, it defaults to
00.
time [date ] Define the base time for starting the job.
time A time specified as one, two, or four digits. One- and two-digit
numbers represent hours; four digits represent hours and minutes.
Alternately, time can be specified as two numbers separated by a
colon (:), a single quote (’), the letter h (h), a period (.), or a
comma (,). Spaces may be present between the separator and
digits representing minutes. If defined in langinfo (5), special time
unit characters can be used.
am or pm can be appended to indicate morning or afternoon. Other-
wise, a 24-hour clock is understood. For example, 0815, 8:15,
8’15, 8h15, 8.15, and 8,15 are read as 15 minutes after eight
in the morning. The suffixes zulu and utc can be used to specify
Coordinated Universal Time (UTC), equivalent to Greenwich Mean
Time (GMT).
The special names
midnight, noon, and now are also recognized.
date A day of the week (fully spelled out or abbreviated) or a date con-
sisting of a day, a month, and optionally a year. The day and year
fields must be numeric, and the month can be either fully spelled
out, abbreviated, or numeric. The fields in the date string are
separated by punctuation marks such as slash (
/), hyphen (-),
period (.), and comma (,). If defined in langinfo (5), special date
