UNIX for Dummies Questions & Answers

I have two sets of tapes for each week days.

Mon_Set_A ____________Tue_Set_B
Tue_Set_A ____________ Tue_Set_B
Wed_Set_A ___________ Wed_Set_B
Thr_Set_A ____________ Thr_Set_B
Fri_Set_A _____________ Fri_Set_B


I have script that does cold backup of database and then back up to tape.

It will be much simpler problem if I only work with one set of tape backup but I have to rotate the tape every other week. For an example, 1st week I use tape backup Set_A and 2nd week backup Set_B, and so on.

There are search result using "Perderabo's date calculator" with "weekselector" that has command

0 0 * * 1 /usr/local/bin/weekselector odd && command1
0 0 * * 1 /usr/local/bin/weekselector even && command2


But I guess above crontab command is not competible in linux environment.


I'm wondering if there are any other way to resolve my issue.

thank you

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.
