What application is responding to PrintScreen? Possibly Openbox?

lucmove · 05-05-2021, 03:32 PM

I use Openbox and I have this command in my ~/.config/openbox/lxde-rc.xml file:

Code:

<!-- Keybinding for PrintScreen Key -->
<keybind key="Print">
  <action name="Execute">
    <execute>scrot -e 'mv $f /home/data/scrot/'</execute>
  </action>
</keybind>

I press PrintScreen and the new screenshot materializes at /home/data/scrot/ as expected. The file name is 2021-05-05-172530_1920x1080_scrot.png.

But an exact copy of the screenshot is also saved to ~/Pictures and the file name is 2021-05-05--1620246330_1920x1080_scrot.png.

Questions:

1) The first file name is obviously made up of the date, time and screen resolution. I can tell because it matches the current date and time exactly. What does '1620246330' in the second file name mean though?

2) How can I find out what application is writing the second file? I really have no idea.

TIA

That would be epoch time. Enter 15:30, about the time that you posted.

Code:

#!/usr/bin/bash

col1=$(tput setaf 2)
col2=$(tput setaf 3)
clr=$(tput sgr0)

message="Enter time-date with format:
12:34 | apr 10 12:34 | apr 10 12:34 2021 | Sat apr 10 12:34 2021

Enter date/time:> "

while :; do
    read -p "${message}" clock_time

    Time_sec=$(date -d "$clock_time" +"%s")

    echo -e ""$col1"\nEpoch time is: "$col2""$Time_sec"\n"$clr""
done

Code:

man scrot
...
-e, --exec APP
              Exec APP on the saved image.

Code:

<execute>scrot -e 'mv $f /home/data/scrot/'</execute>

Your first comment is about the epoch time, and yes, it's correct.
I don't understand your second comment.

You can use xev to view the output of "Print Sceen." That could cast some light on what happens when you press that key.

Be forewarned, the output of pressing a single key is more voluminous than one might expect.

That much is clear and unambiguous.

What that other file is and where it came from, who knows? Sleepwalking on the keyboard?
Does it happen every time you take a screenshot? That you end up with two files? Show us.

Yes, every time. Of course it is every time. That should be obvious.

Show us the filenames for both files, preferably at least 3 pairs.
