Display the day prior to the current DOW.

[kozlow]

I have logs that have the current DOW at the end. I used `date +%a`

for example TEST.log.Tue

Is there a simple way to use the date command to return the prior DOW? Example: If it is Wed, I would like to work on Tue log.

I know I can use a case statement, but that there has to be an one line way.....

Thanks....

The way we do it is to write a text file using cron containing the date in the format we require at (say) 23:59 on the day before and then reference that file to rename logs as required.

echo `(export TZ=XYZ+24; date "+%a")`

will show the previous day
