How to order servers realization some operation automatically regularly once in month ?
For example first or of last day of month to record file on disc or to write information to database.

crack open vi and type in:
01 0 1 tar cf /bak /home/users/me
and save it as say, my_crontab.txt

then at the command line just type in:
crontab -u userName /path/to/my_crontab.txt

and once a month, cron will exec the command in your tab file.

If you want more info, troll some of the various *nix boards like bsd.org or what have you, they all have crontab in the dist.
