Get today’s date and use it in filename

rated 0 times [ 13] [ 0] / answers: 1 / hits: 31940 / 2 Years ago, tue, august 2, 2022, 3:43:12

Using the command-line, I want to create a log file with today's date in the name (for example, today is 05/17/2011, so the filename would have to be log051711).

I know how to create the file (touch filename), but I don't know how to get today's date. I have looked at the manual for date, but it seems that I can't really format its output?

Any help would be appreciated.

You can format the output using the '+FORMAT' parameter, e.g.

touch "log$(date +'%m%d%y')"

See the manpage for what sequences you can use in FORMAT.
