Hi Gurus,
I want to run some jobs from monday to thursday and some only on friday. can you please help me for this command.

I put like this:

30 00 1-4 * * /home/oracle/test.sh

45 01 5 * * /home/oracle/test1.sh

but this is not working. why is it so?

Can any one let me know some sites which tell in detail about crons in linux??

Thanks in advance
