Take a screenshot from commandline

@iafonov Thanks for the link!!!
BTW, I have to check, but it seems like the lib use the interface Xvfb, but I don't know if it could be used against a running X server. I wanted to take a screenshot of what is currently at the display :0.
Do you know if this is possible? Thanks in advance.

@vinitcool76 Well, I'll say 'scrot' is another tool to do it (as 'xwd'), but I don't really see how is better.
I used 'import' because I have already installed 'ImageMagick' and have a lot of interesting options, but I guess I could use 'scrot' as well.
I don't see that 'scrot' have a 'display' option, so I guess I should export first the 'DISPLAY=:0' variable to be able of taking the screenshot through ssh.

@vinitcool76 I haven't said that there is a problem with 'scrot' taking screenshots on remote systems, just that it's probably that it need to export the DISPLAY variable to be able to access to the X server.
That's normal behavior. I mean, any app (command line or not) to access to an object of the graphical session (for example, the current aspect of the desktop) need to know the DISPLAY where is running.
'import' has a option to specify that variable, instead of export it to your shell environment, but it's just a handy utility. That's what I was saying.
About the 'delay' option, I also think that is a handy feature, and 'import' has it as well. Among others useful features.
But both tools are valid tools for the task. It's good to know them all and decide which one use based on what you really need or you like the most.
Thanks for your comments. Cheers.
