And to further narrow it down to what the OP asked for: `stat –printf=’%s’ -f .`

Note for non-U.S. folks: the input date is in M/D/Y format. (I’d edit the answer to use something like ”12/31/2012” as an example to make this more apparent, but the edit queue is currently full.)

`[ ”$c” != ”” ]` is `false` for completely empty files which is contrary to what I’d expect.

Reading from the Codex page linked to, I think the value of ’field’ in the tax_query array should be ’term_id’ rather than ’id’: ”Possible values are ’term_id’, ’name’ and ’slug’. Default value is ’term_id’.” I’m guessing ’id’ only works because it causes a fall-back to the default.

I would highly recommend Daniel’s much simpler solution over the one currently selected as correct:

$user = get_userdata( $user_id );
if ( $user == false ) {
    //user id does not exist
} else {
    //user id exists
}

I have the exact same problem with the exact same scanner (but I’m running 64-bit Ubuntu w/Linux 3.13.0-45). Sometimes instead of error -110 the logs show the device as being identified correctly, but immediately followed by ”string descriptor 0 read error: -32”. On very rare occasions it just works (no errors when plugged in, identified correctly and scanning works).-110 apparently means not enough power, which is doubly funny because the damn thing has its own power source, and surely a desktop PSU has more power than a laptop…

This looks slightly more straightforward than thebodzio’s method, so I’m picking this as answering my original query for ”easiest”. For some reason both Colorify and Colorize have been translated as ”Väritä” in my (Finnish) locale, so it would’ve been difficult to realize it’s actually two different functions. They’re not particularly easy to tell apart in English either…

Brilliant, this seems to work exactly as I wanted! And it seems to work for non-greyscale originals as well. Thank you!

I have an image I wish to colorize using a picked color. What is the handiest/easiest way to do this in GIMP?

I’ve tried my best by checking the palette for my picked color’s HSV, then using it as starting point to find corresponding HSL values for the Colorize window. But this seems absurdly difficult and imprecise. I don’t do much image processing, but I repeatedly come across this specific problem, so there must be a better way that I just don’t know about.

I believe the correct way, as per the Desktop Application Autostart Specification, is to create user-specific configuration overriding the system default.

1. cd ~/.config/autostart
2. cp /etc/xdg/autostart/bluetooth-applet* .
3. echo ”Hidden=true” | tee -a bluetooth-applet*
