Rep:
To what process does this window belong to ?
Dear LQ,xprop. Sometimes, it prints WM_COMMAND and I can figure out what process a window belongs to, but sometimes WM_COMMAND isn't printed (tried with libreoffice and firefox).

Hi.

...So let's assume you know a window-id, e.g. 0x1600045, and want to find, what's the process owning it.
Code:
xkill -id 0x1600045

Just a quick search example:
linux window process info if I had my laptop I'd try it and see, you're on Debian-KDE?
Add: some process managers (like
top for example or GUI ones) have a lot of extra tweaks...

I found the solution given in the question itself (using _NET_WM_PID )

Thank you pan64 I saw your post and link. The stackexchange link
mentioned that the author didn't want to rely on
_NET_WM_PID
though, because he thinks some apps might not set.
It's always interesting to see the many ways you can implement the
solution based on the same data. Here's what I came up with :
Code:
alias wid='xprop | (pid=$(command grep PID); echo ${pid##*=}) | xargs ps'
usage :
Code:
ychaouche#ychaouche-PC 10:31:11 ~ $ wid <click>
PID TTY STAT TIME COMMAND
9531 ? Sl 0:26 /usr/bin/xchat
ychaouche#ychaouche-PC 10:31:16 ~ $

I shouldn't need that xargs, what do you guys think of
Code:
ps $(xprop | (pid=$(command grep PID); echo ${pid##*=}))
