at is usually for non-regular, one-time-only jobs while cron is usually for regular, perpetual jobs ...
at samples:
cron samples:
however, you can also get a job to go regularly with an at command by adding something like this in your script ...
... and a "one-time" job in cron ... (will only run when all time conditions are met) ...
btw, it would be best if you get into checking the man pages while you're just starting ... see "man at" and "man crontab" ...

console
console(7D) Devices console(7D)NAME
console - STREAMS-based console interface
SYNOPSIS
/dev/console
DESCRIPTION
The file /dev/console refers to the system console device. /dev/console should be used for interactive purposes only. Use of /dev/console
for logging purposes is discouraged; syslog(3C) or msglog(7D) should be used instead.
The identity of this device depends on the EEPROM or NVRAM settings in effect at the most recent system reboot; by default, it is the
``workstation console'' device consisting of the workstation keyboard and frame buffer acting in concert to emulate an ASCII terminal (see
wscons(7D)).
Regardless of the system configuration, the console device provides asynchronous serial driver semantics so that, in conjunction with the
STREAMS line discipline module ldterm(7M), it supports the termio(7I) terminal interface.
SEE ALSO syslog(3C), termios(3C), ldterm(7M), termio(7I), msglog(7D), wscons(7D)NOTES
In contrast to pre-SunOS 5.0 releases, it is no longer possible to redirect I/O intended for /dev/console to some other device. Instead,
redirection now applies to the workstation console device using a revised programming interface (see wscons(7D)). Since the system console
is normally configured to be the work station console, the overall effect is largely unchanged from previous releases.
See wscons(7D) for detailed descriptions of control sequence syntax, ANSI control functions, control character functions and escape
sequence functions.
