UNIX for Dummies Questions & Answers

Hello,

How can I set up events to be executed at a certain time? And do I need some kind of privilege such as being in cron group?

You create cron entries or use the "at" command. On most systems both of these things are protected because they can be exploited - ie., hacked.

try
man at

man cron

Good Afternoon. You have many tricks in unix to play with. most simple one is the sleep command.if you know that you will run the command after 15 minutes,say echo "$LOGNAME". (sleep 900; echo $LOGNAME) > $LOGNAME.log &. If you dont like a sleep type, then you could use either at or cron command. you need to have the permission to run this. you may just check out the permission by just typing "at" and if does not give any bad remark then you fine.

at now +11 minute <command.list

in the command.list you could write down any thing you like to be done.

cron is more robust and you could run and rerun the commands. you have to make a file with and then run that as an argument with crontab. crontab mylist.

thanks.
