Filenames based on the date

How do I create a filename based on the date?

i.e.

I'd like to run 'date' from the prompt, and create a file based upon that.

for example, create a file with the prefix 'test-' which would create a file with a name like:

test-Fri Nov 18 16:38:50 GMT 2005.txt

Thanks.

Code:

$ touch "test-`date`.txt"

You might want something like this for easier sorting:

Code:

touch "test-`date +%Y%m%d`"

You'll live to regret creating filenames with spaces on Linux systems.

How about:

Code:

touch $( echo "test-$( date )" | sed 's/ //g' )

No more spaces.

Or better still:

Code:

touch $( echo "test-$( date )" | sed -e 's/ //g' -e 's/\://g' )

No more spaces, no more colons.

edit: blindcoder's is good too. Nice and short.
