This command takes a 1280x1024 p picture from the webcam.

If prefer it smaller, try changing the -s parameter: qqvga is the tiniest, vga is 640x480, svga is 800x600 and so on.

Get your smile on and press enter! :)

Show all available colors on your terminal.

Using perl and tput, show all the colors with numbers that your actual $TERM can handle.

If want to remove the numbers at beginning of new line, it should be something like this:

perl -E 'say `tput setb $_`," "x `tput cols`, `tput sgr0` for 0 .. (`tput colors` - 1)'

List all symbolic links in current directory that matches regexp

Perl alternative to list symlinks with a clumsy regexp filter: place the regex instead of he example 'libxml' and end it with a wildchar to see the results (previous cd on dir).

Is it possible change the '-l' test for '-d' and it will search for directories. [Same applies for -x and -X. See $(perldoc -f -x) for more tests].

I use it quite often when dealing with shared libraries...
