Question:
Is the command “at” available for me to use? When i issued an at command, i got the following message:
Can’t open /var/run/atd.pid to signal atd. No atd running?
Answer:
To keep servers running as fast as possible, we no longer offer atd service. While Atd is not a large drain on system resources we try to keep as few non-critical processes running as possible. We do offer crond. Cron can replicate (and goes beyond) most of atd’s functionality.
You can edit your crontab with the command :
crontab -e
from inside of ssh.
