Hi,

I'm using in Ubuntu the command "import capture.png" to save a screen capture to the file capture.png, but I need that every time that I run this command, the filename will be updated include the date and time , for example:

capture2013-11-14-2200.png or something like this

I try to with the command "import capture$date(%Y-%m%d)" but doesn't work.

Could you give me the command to dynamic generate the filename including datetime stamp?

Thanks in advance

Thanks, but your command generate a file named "capture$(date +%Y-%m-%d-%H%M).png"

I see that between date and + there are a space, I try with and without space with the same results

I'm using Ubuntu 10.04 LTS

Which shell are you using?
If it doesn't understand $(date +%Y-%m-%d-%H%M), try `date +%Y-%m-%d-%H%M`

The standard for Ubuntu, I think that is bash.

The other option is including the character ' ?

bash understands $(), what was the exact command you used?
Where do you want to include the character ' ?
You can include it literally by enclosing it in "'", otherwise $() and `` would both be disabled inside ''

import capture$(date +%Y-%m-%d-%H%M).png

won't produce a file called

capture$(date +%Y-%m-%d-%H%M).png

Can you please copy/paste the exact command you are running.
