date - Shell Programming and Scripting

It might vary by the system's version of date, but something like the following might work:

Code:

export my_date=$(date +'%w') 

if [[ $my_date = '0' ]] || [[ $my_date = '6' ]] 
then
...
fi

or

Code:

export my_date=$(date +'%u') 

if [[ $my_date = '6' ]] || [[ $my_date = '7' ]] 
then
...
fi

Note, that the above varies by ksh93's version of date. But you'd really only want this to run once a day, no? What is there to block the job if it's already running/been run that day...?
