So I need to convert a date to a different format. With a bash pipeline, I'm taking the date from the last console login, and pulling the relevant bits out with awk, like so:
last $USER | grep console | head -1 | awk '{print $4, $5}'
Which outputs: Aug 08
($4=Aug $5=08, in this case.)
Now, I want to take 'Aug 08' and put it into a date command to change the format to a numerical date.
Which would look something like this:
date -j -f %b\ %d Aug\ 08 +%m-%d
Outputs: 08-08
The question I have is, how do I add that to my pipeline and use the awk variables $4 and $5 where 'Aug 08' is in that date command?
