Where it's at

[Langstracht]

I think I must be missing something real simple, and real basic, but my problem is, if you will, "converting" terminal commands so as to have them run later with "at".

I think maybe the problem is that at is running in a different directory than the one terminal is using. However, anything that would tell me where (ls, pwd) don't run in at either.

Can anyone straighten me out here? Please and thank you.

NAME

at, batch, atq, atrm - queue, examine or delete jobs for later execution SYNOPSIS

at [-V] [-q queue] [-f file] [-mldbv] TIME
at -c job [job...]
atq [-V] [-q queue]
atrm [-V] job [job...]
batch [-V] [-q queue] [-f file] [-mv] [TIME] DESCRIPTION

at and batch read commands from standard input or a specified file which are to be executed at a later time, using the shell set by the user's environment variable SHELL, the user's login shell, or ultimately /bin/sh. at executes commands at a specified time. atq lists the user's pending jobs, unless the user is the superuser; in that case, everybody's jobs are listed. The format of the output lines (one for each job) is: Job number, date, hour, job class. atrm deletes jobs, identified by their job number. batch executes commands when system load levels permit; in other words, when the load average drops below 0.8, or the value specified in the invocation of atrun. At allows fairly complex time specifications, extending the POSIX.2 standard. It accepts times of the form HH:MM to run a job at a specific time of day. (If that time is already past, the next day is assumed.) You may also specify midnight, noon, or teatime (4pm) and you can have a time-of-day suffixed with AM or PM for running in the morning or the evening. You can also say what day the job will be run, by giving a date in the form month-name day with an optional year, or giving a date of the form MMDDYY or MM/DD/YY or DD.MM.YY. The specification of a date must follow the specification of the time of day. You can also give times like now + count time-units, where the time-units can be minutes, hours, days, or weeks and you can tell at to run the job today by suffixing the time with today and to run the job tomorrow by suffixing the time with tomorrow.
For example, to run a job at 4pm three days from now, you would do at 4pm + 3 days, to run a job at 10:00am on July 31, you would do at 10am Jul 31 and to run a job at 1am tomorrow, you would do at 1am tomorrow.
/usr/share/doc/at-3.1.8/timespec contains the exact definition of the time specification.
For both at and batch, commands are read from standard input or the file specified with the -f option and executed. The working directory, the environment (except for the variables TERM, DISPLAY and _) and the umask are retained from the time of invocation. An at - or batch - command invoked from a su (http://linux.about.com/library/cmd/blcmdl1_su.htm)(1) shell will retain the current userid. The user will be mailed standard error and standard output from his commands, if any. Mail will be sent using the command /usr/sbin/sendmail. If at is executed from a su (http://linux.about.com/library/cmd/blcmdl1_su.htm)(1) shell, the owner of the login shell will receive the mail.
The superuser may use these commands in any case. For other users, permission to use at is determined by the files /etc/at.allow and /etc/at.deny.
If the file /etc/at.allow exists, only usernames mentioned in it are allowed to use at.
If /etc/at.allow does not exist, /etc/at.deny is checked, every username not mentioned in it is then allowed to use at.
If neither exists, only the superuser is allowed use of at.
An empty /etc/at.deny means that every user is allowed use these commands, this is the default configuration.

Thanks for the immediate response.

As it is I have already read the manual page a number of times ... and was/am no further ahead.

A simple "use blah/blah/filename" instead of the terminal command (just) "filename" would be much appreciated.

Thank you.
