I don't quite understand what you want. The format of a line in a
crontab file is as follows. There are five columns that specify the
time to run the job at:
Minutes Hours Day of Month Month Day of week
59 23 * * * /path/to/script
Would run /path/to/script every day at 11:59 pm. If what you want to
do is only run it on tuesday,
59 23 * * 2 /path/to/script
The utility to install crontabs is called crontab. The format of
entries is defined in the crontab(5) man page. 'man 5 crontab' will
allow you to read that.
