Delete line if date=today

Hi,

I'm trying to write a script that looks at a file, and if the date (dd/mm/yyyy) equals today's date, then delete the line.
I've tried passed the date into sed, but no success.

Any help would be much appreciated.

Use grep:

Code:
grep -v "$(date +%d/%m/%Y)" file

[...]
The `/' in the format of your variable, most likely, is messing your command up.

Try:
(escaping the /)

Code:
today=`date "+%d\/%m\/%Y"`
sed /$today/d file
